oBeaver — A Beaver That Runs LLMs on Your Machine 🦫
Hi there! I'm the creator of oBeaver. This project started from a pretty simple desire: I wanted to run large language models on my own computer. No data sent to the cloud. No API keys. No per-call charges. I'm guessing you've had the same thought. There are already great tools out there — Ollama being the most prominent. But in my day-to-day work, I spend a lot of time in the ONNX ecosystem — the cross-platform reach of ONNX Runtime, its native NPU support, the turnkey experience of Microsoft Foundry Local. It kept nagging at me: the ONNX ecosystem deserves a more complete local inference toolkit. That's how oBeaver was born. Here are the links if you want to jump straight in: GitHub: https://github.com/microsoft/obeaver Docs: https://microsoft.github.io/obeaver Up and Running in Three Minutes Getting started with oBeaver is dead simple. You need Python 3.12+, then it's clone, install, chat: git clone https://github.com/microsoft/obeaver.git cd obeaver pip install -e . # Initialize the model directory (auto-creates ort/, foundrylocal/, cache_dir/ sub-folders) obeaver init # Make sure everything looks good obeaver check If you're on macOS or Windows, install Foundry Local and you're one command away from chatting with a model: obeaver run phi-4-mini The first run downloads the model automatically — give it a minute. After that, it's instant. On Linux, or if you want to use models from Hugging Face, the ORT engine has you covered: # Convert Qwen3-0.6B from Hugging Face to ONNX format obeaver convert Qwen/Qwen3-0.6B # Run it with the ORT engine obeaver run --engine ort ./models/ort/Qwen3-0.6B_ONNX_INT4_CPU Want to turn your model into an HTTP service? One line: obeaver serve Phi-4-mini Then point any OpenAI-compatible client at it — just change one base_url and your existing code works as-is: from openai import OpenAI client = OpenAI(base_url="http://127.0.0.1:18000/v1", api_key="unused") response = client.chat.completions.create( model="Phi-4-mini", messages=[{"role": "user", "content": "What is the capital of France?"}], stream=True, ) for chunk in response: print(chunk.choices[0].delta.content or "", end="", flush=True) LangChain, LlamaIndex, Microsoft Agent Framework, CrewAI — anything that speaks the OpenAI protocol plugs right in. This was a non-negotiable design principle from day one: local inference shouldn't be an island; it should fit seamlessly into your existing dev workflow. "Why Not Just Use Ollama?" I get this question a lot, and it deserves a straight answer. Ollama is a fantastic project. It pioneered the "one command to run a model" experience and made local LLM inference accessible to everyone. If all you need is a quick way to chat with a model locally, Ollama is still a wonderful choice. oBeaver itself draws heavy inspiration from it. But Ollama and oBeaver take different technical paths. Ollama is built on llama.cpp and uses the GGUF model format. oBeaver is built on ONNX Runtime and uses the ONNX model format. Behind these two formats are two very different philosophies. GGUF: Grab and Go GGUF's strength is ultimate portability. One file bundles everything — weights, tokenizer, metadata. Hugging Face is packed with pre-quantized GGUF models ready to download and run. Quantization options are rich (Q2_K through Q8_0), and the community is incredibly active. For individual developers, this "grab and go" experience is hard to beat. ONNX: Convert Once, Accelerate Everywhere ONNX shines in a different dimension. As a cross-platform industrial standard, ONNX Runtime has something called Execution Providers — the same ONNX model, without any changes, can run on CPU, GPU, and even NPU. This matters more than it might seem at first glance. With chips like Intel Core Ultra, Qualcomm Snapdragon X, and Apple Neural Engine becoming mainstream, NPUs are quickly becoming standard hardware in AI PCs. ONNX Runtime already supports NPU acceleration natively, while the GGUF ecosystem doesn't have this capability yet. This means ONNX naturally adapts to a far wider range of devices — from servers to laptops, from desktops to edge devices, even phones and IoT endpoints. The ONNX model you run on CPU today can be accelerated on an NPU-equipped machine tomorrow — no re-conversion, no code changes, just switch the Execution Provider. ONNX does have a higher barrier to entry — models need to be converted first. But oBeaver's built-in obeaver convert command, powered by Microsoft's Olive toolkit, reduces that to a single line. Another project worth mentioning is oMLX, which also explores local inference in the ONNX ecosystem, but focuses specifically on Apple Silicon. oBeaver aims to be more comprehensive — spanning macOS, Windows, and Linux, covering text chat, embeddings, and vision-language scenarios. Here's a quick comparison of all three: Ollama oMLX oBeaver Model format GGUF ONNX ONNX Inference backend llama.cpp ONNX Runtime Foundry Local + ORT GenAI Platforms macOS/Linux/Windows macOS macOS/Windows/Linux NPU acceleration ❌ ❌ ✅ Embedding models ✅ ✅ ✅ VL models ✅ ✅ ✅ Function Calling ✅ ✅ ✅ Docker deployment ✅ ✅ ✅ I'm not saying oBeaver is better than Ollama. They serve different needs. But if your work involves the ONNX ecosystem, NPU acceleration, or a combination of embedding and multimodal capabilities, oBeaver offers a path that Ollama doesn't currently cover. Why a "Dual Engine"? This is oBeaver's most distinctive design decision, and the one I spent the most time thinking about. oBeaver has two inference engines under the hood: Foundry Local and ONNX Runtime GenAI (ORT). Why not just pick one? Because reality is messier than ideals. Foundry Local is Microsoft's local inference runtime, and the experience is lovely — pass a catalog alias like Phi-4-mini, and it auto-downloads, loads, and runs the model with smart hardware scheduling (NPU > GPU > CPU). But it has two clear limitations: first, the model catalog is still small, mostly centered around Microsoft's Phi family; second, it only supports macOS and Windows — Linux users are left out. ONNX Runtime GenAI fills exactly those gaps. It supports macOS, Windows, and Linux — all three platforms. And with obeaver convert, you can transform almost any model on Hugging Face into ONNX format, giving you a much wider model selection. Right now, oBeaver can already run models from Phi, Qwen, Gemma, GLM, and other SLM families through the ORT engine. On top of that, the ORT engine powers capabilities that Foundry Local simply can't do: Embedding models — The ORT engine includes a dedicated embedding engine supporting Qwen3-Embedding and EmbeddingGemma, perfect for local RAG pipelines: # Start the embedding service obeaver serve-embed ./models/Qwen3-Embedding-0.6B from openai import OpenAI client = OpenAI(base_url="http://127.0.0.1:18001/v1", api_key="unused") response = client.embeddings.create( model="Qwen3-Embedding-0.6B", input=["Hello, world!", "Embeddings are useful."], ) for item in response.data: print(f"index={item.index} dim={len(item.embedding)}") Vision-Language models (VL) — When the ORT engine detects vision.onnx in a model directory, it automatically switches to VL mode. Currently supported: Qwen-2.5-VL-3B and Qwen-3-VL-2B. You can send images alongside text for multimodal understanding: obeaver serve ./models/Qwen3-VL-2B-Instruct_VL_ONNX_INT4_CPU Converting a VL model is just one command too: obeaver convert Qwen/Qwen2.5-VL-3B-Instruct --type vl So the dual engine isn't redundancy — it's the optimal choice given reality: Foundry Local covers only macOS/Windows; ORT GenAI covers all platforms. Foundry Local has fewer models but zero friction; ORT GenAI has more models and more flexibility. oBeaver automatically picks the right engine for your platform and task — Foundry Local by default on macOS/Windows, ORT on Linux, auto-switching to ORT for embedding or VL workloads. You can always override with --engine ort. In short: Foundry Local handles the "just works" path, ORT handles the "I need more" path. Together, they give oBeaver an answer for every platform and every scenario. Cloud-Native? Of Course oBeaver isn't just a local toy. Deployment was baked into the design from the start. The architecture is cleanly layered: CLI (Typer) → FastAPI Server → pluggable inference engines. We ship a Docker image supporting both linux/amd64 and linux/arm64 (Apple Silicon included): # Build the image docker buildx build --platform=linux/amd64 \ -f docker/Dockerfile.cpu -t obeaver-cpu . # Start the API server docker run -d --rm -p 18000:18000 \ -v /path/to/models:/models \ obeaver-cpu serve -m /models -E ort --host 0.0.0.0 --port 18000 Local dev, CI/CD pipelines, headless servers, Kubernetes clusters — it all works. Combined with the OpenAI-compatible API, you can develop against oBeaver locally and switch to a cloud endpoint in production by changing a single URL. Not a single line of application code needs to change. Not Just a CLI — There's a Dashboard Too So far everything I've shown has been terminal commands. But sometimes you just want a visual interface — especially when you're evaluating models, comparing performance, or showing a demo. oBeaver ships with a built-in web dashboard. One command to launch: obeaver dashboard # Foundry Local engine (macOS/Windows) obeaver dashboard -e ort # ORT engine (scans local ONNX models) Open http://127.0.0.1:1573/ and you'll see something like this: It's a real-time monitoring and chat interface rolled into one. Here's what you get: Model Selector — Switch between your cached models on the fly. If a model supports NPU acceleration, it's marked with a ⚡ badge. With Foundry Local, you'll see the models from your local catalog: With the ORT engine, it scans your model directory for all available ONNX models: Chat + Live Benchmarking — Send messages and get streaming responses, with real-time performance stats right in the interface — TTFT (Time to First Token), tokens per second, total token count. This makes it incredibly easy to benchmark different models side by side: System Monitoring — Real-time memory gauges for CPU, GPU, NPU, and process memory. A system info bar shows the current model, engine type, platform, and health status at a glance. Inference Parameters — Adjust temperature, top-p, top-k, and max tokens with built-in presets, all without restarting the server. VL Mode — When you load a Vision-Language model in the ORT dashboard, the interface automatically switches to a dedicated VL mode where you can provide an image URL alongside your text prompt: And more — Conversation history with save/load, system prompt configuration, live server logs showing every request with method/path/status/timing, and export to JSON or Markdown. The dashboard isn't a separate product — it's just obeaver dashboard. Everything runs locally, nothing phones home. It's particularly useful when you want to quickly evaluate how a model performs on your hardware before committing to it in your application. Being Honest: CPU Only for Now oBeaver is currently in Tech Preview, and I want to be upfront about this — it only supports CPU inference right now. This is a deliberate, stage-by-stage choice. We wanted to make sure the entire toolchain — model conversion, inference, API serving, Docker deployment — is rock solid on CPU first. Almost every machine has a CPU; it's the best baseline for validating the complete workflow. But GPU and NPU support are coming soon. They're at the very top of the roadmap. ONNX Runtime already ships mature CUDA (GPU) and QNN/OpenVINO (NPU) Execution Providers. Foundry Local already has NPU > GPU > CPU auto-scheduling built in. What oBeaver needs to do is integrate these into its engine selection logic and model conversion pipeline — and that work is actively underway. Ultimately, one of the key reasons oBeaver chose the ONNX path is the NPU future. The AI PC era is arriving, and when NPUs become standard hardware, ONNX will be the ecosystem most ready for it. Acknowledgements oBeaver is inspired by and builds upon the ideas from the following excellent projects: Project Description Ollama Run large language models locally with a simple CLI OMLX Run large language models on Apple Silicon, ONNX-based vLLM High-throughput and memory-efficient inference engine for LLMs Foundry Local Microsoft's local model inference runtime with NPU/GPU/CPU acceleration ONNX Runtime GenAI Generative AI extensions for ONNX Runtime Olive Microsoft's model optimization toolkit for ONNX Runtime I Need Your Feedback That's the tour. But oBeaver is still in its early days, and there's so much room to improve. As the creator of this project, what I fear most isn't criticism — it's silence. So I genuinely hope you'll give it a try and let me know what you think: Which models do you most want to run? How urgent is GPU / NPU acceleration for your use case? What do you think of the dual-engine design — does it add value, or does it add complexity? In your real-world projects, what's the biggest pain point with local inference? What else does the Docker story need? Helm Charts? Compose files? GitHub Issues, PRs, or just reaching out on social media — any form of feedback is deeply appreciated. The name oBeaver comes from the beaver — nature's most remarkable engineer. Beavers build dams stick by stick, creating the environment they need to thrive. I hope oBeaver can help you do the same: build your local AI infrastructure, one piece at a time, on your own hardware. Build local. Dam the cloud. 🦫 GitHub: https://github.com/microsoft/obeaver Docs: https://microsoft.github.io/obeaver If you find oBeaver useful, a ⭐ on GitHub means the world to us!Building an Offline AI Interview Coach with Foundry Local, RAG, and SQLite
How to build a 100% offline, AI-powered interview preparation tool using Microsoft Foundry Local, Retrieval-Augmented Generation, and nothing but JavaScript. Foundry Local 100% Offline RAG + TF-IDF JavaScript / Node.js Contents Introduction What is RAG and Why Offline? Architecture Overview Setting Up Foundry Local Building the RAG Pipeline The Chat Engine Dual Interfaces: Web & CLI Testing Adapting for Your Own Use Case What I Learned Getting Started Introduction Imagine preparing for a job interview with an AI assistant that knows your CV inside and out, understands the job you're applying for, and generates tailored questions, all without ever sending your data to the cloud. That's exactly what Interview Doctor does. Interview Doctor's web UI, a polished, dark-themed interface running entirely on your local machine. In this post, I'll walk you through how I built an interview prep tool as a fully offline JavaScript application using: Foundry Local — Microsoft's on-device AI runtime SQLite — for storing document chunks and TF-IDF vectors RAG (Retrieval-Augmented Generation) — to ground the AI in your actual documents Express.js — for the web server Node.js built-in test runner — for testing with zero extra dependencies No cloud. No API keys. No internet required. Everything runs on your machine. What is RAG and Why Does It Matter? Retrieval-Augmented Generation (RAG) is a pattern that makes AI models dramatically more useful for domain-specific tasks. Instead of relying solely on what a model learned during training (which can be outdated or generic), RAG: Retrieves relevant chunks from your own documents Augments the model's prompt with those chunks as context Generates a response grounded in your actual data For Interview Doctor, this means the AI doesn't just ask generic interview questions, it asks questions specific to your CV, your experience, and the specific job you're applying for. Why Offline RAG? Privacy is the obvious benefit, your CV and job applications never leave your device. But there's more: No API costs — run as many queries as you want No rate limits — iterate rapidly during your prep Works anywhere — on a plane, in a café with bad Wi-Fi, anywhere Consistent performance — no cold starts, no API latency Architecture Overview Complete architecture showing all components and data flow. The application has two interfaces (CLI and Web) that share the same core engine: Document Ingestion — PDFs and markdown files are chunked and indexed Vector Store — SQLite stores chunks with TF-IDF vectors Retrieval — queries are matched against stored chunks using cosine similarity Generation — relevant chunks are injected into the prompt sent to the local LLM Step 1: Setting Up Foundry Local First, install Foundry Local: # Windows winget install Microsoft.FoundryLocal # macOS brew install microsoft/foundrylocal/foundrylocal The JavaScript SDK handles everything else — starting the service, downloading the model, and connecting: import { FoundryLocalManager } from "foundry-local-sdk"; import { OpenAI } from "openai"; const manager = new FoundryLocalManager(); const modelInfo = await manager.init("phi-3.5-mini"); // Foundry Local exposes an OpenAI-compatible API const openai = new OpenAI({ baseURL: manager.endpoint, // Dynamic port, discovered by SDK apiKey: manager.apiKey, }); ⚠️ Key Insight Foundry Local uses a dynamic port never hardcode localhost:5272 . Always use manager.endpoint which is discovered by the SDK at runtime. Step 2: Building the RAG Pipeline Document Chunking Documents are split into overlapping chunks of ~200 tokens. The overlap ensures important context isn't lost at chunk boundaries: export function chunkText(text, maxTokens = 200, overlapTokens = 25) { const words = text.split(/\s+/).filter(Boolean); if (words.length <= maxTokens) return [text.trim()]; const chunks = []; let start = 0; while (start < words.length) { const end = Math.min(start + maxTokens, words.length); chunks.push(words.slice(start, end).join(" ")); if (end >= words.length) break; start = end - overlapTokens; } return chunks; } Why 200 tokens with 25-token overlap? Small chunks keep retrieved context compact for the model's limited context window. Overlap prevents information loss at boundaries. And it's all pure string operations, no dependencies needed. TF-IDF Vectors Instead of using a separate embedding model (which would consume precious memory alongside the LLM), we use TF-IDF, a classic information retrieval technique: export function termFrequency(text) { const tf = new Map(); const tokens = text .toLowerCase() .replace(/[^a-z0-9\-']/g, " ") .split(/\s+/) .filter((t) => t.length > 1); for (const t of tokens) { tf.set(t, (tf.get(t) || 0) + 1); } return tf; } export function cosineSimilarity(a, b) { let dot = 0, normA = 0, normB = 0; for (const [term, freq] of a) { normA += freq * freq; if (b.has(term)) dot += freq * b.get(term); } for (const [, freq] of b) normB += freq * freq; if (normA === 0 || normB === 0) return 0; return dot / (Math.sqrt(normA) * Math.sqrt(normB)); } Each document chunk becomes a sparse vector of word frequencies. At query time, we compute cosine similarity between the query vector and all stored chunk vectors to find the most relevant matches. SQLite as a Vector Store Chunks and their TF-IDF vectors are stored in SQLite using sql.js (pure JavaScript — no native compilation needed): export class VectorStore { // Created via: const store = await VectorStore.create(dbPath) insert(docId, title, category, chunkIndex, content) { const tf = termFrequency(content); const tfJson = JSON.stringify([...tf]); this.db.run( "INSERT INTO chunks (...) VALUES (?, ?, ?, ?, ?, ?)", [docId, title, category, chunkIndex, content, tfJson] ); this.save(); } search(query, topK = 5) { const queryTf = termFrequency(query); // Score each chunk by cosine similarity, return top-K } } 💡 Why SQLite for Vectors? For a CV plus a few job descriptions (dozens of chunks), brute-force cosine similarity over SQLite rows is near-instant (~1ms). No need for Pinecone, Qdrant, or Chroma — just a single .db file on disk. Step 3: The RAG Chat Engine The chat engine ties retrieval and generation together: async *queryStream(userMessage, history = []) { // 1. Retrieve relevant CV/JD chunks const chunks = this.retrieve(userMessage); const context = this._buildContext(chunks); // 2. Build the prompt with retrieved context const messages = [ { role: "system", content: SYSTEM_PROMPT }, { role: "system", content: `Retrieved context:\n\n${context}` }, ...history, { role: "user", content: userMessage }, ]; // 3. Stream from the local model const stream = await this.openai.chat.completions.create({ model: this.modelId, messages, temperature: 0.3, stream: true, }); // 4. Yield chunks as they arrive for await (const chunk of stream) { const content = chunk.choices[0]?.delta?.content; if (content) yield { type: "text", data: content }; } } The flow is straightforward: vectorize the query, retrieve with cosine similarity, build a prompt with context, and stream from the local LLM. The temperature: 0.3 keeps responses focused — important for interview preparation where consistency matters. Step 4: Dual Interfaces — Web & CLI Web UI The web frontend is a single HTML file with inline CSS and JavaScript — no build step, no framework, no React or Vue. It communicates with the Express backend via REST and SSE: File upload via multipart/form-data Streaming chat via Server-Sent Events (SSE) Quick-action buttons for common follow-up queries (coaching tips, gap analysis, mock interview) The setup form with job title, seniority level, and a pasted job description — ready to generate tailored interview questions. CLI The CLI provides the same experience in the terminal with ANSI-coloured output: npm run cli It walks you through uploading your CV, entering the job details, and then generates streaming questions. Follow-up questions work interactively. Both interfaces share the same ChatEngine class, they're thin layers over identical logic. Edge Mode For constrained devices, toggle Edge mode to use a compact system prompt that fits within smaller context windows: Edge mode activated, uses a minimal prompt for devices with limited resources. Step 5: Testing Tests use the Node.js built-in test runner, no Jest, no Mocha, no extra dependencies: import { describe, it } from "node:test"; import assert from "node:assert/strict"; describe("chunkText", () => { it("returns single chunk for short text", () => { const chunks = chunkText("short text", 200, 25); assert.equal(chunks.length, 1); }); it("maintains overlap between chunks", () => { // Verifies overlapping tokens between consecutive chunks }); }); npm test Tests cover the chunker, vector store, config, prompts, and server API contract, all without needing Foundry Local running. Adapting for Your Own Use Case Interview Doctor is a pattern, not just a product. You can adapt it for any domain: What to Change How Domain documents Replace files in docs/ with your content System prompt Edit src/prompts.js Chunk sizes Adjust config.chunkSize and config.chunkOverlap Model Change config.model — run foundry model list UI Modify public/index.html — it's a single file Ideas for Adaptation Customer support bot — ingest your product docs and FAQs Code review assistant — ingest coding standards and best practices Study guide — ingest textbooks and lecture notes Compliance checker — ingest regulatory documents Onboarding assistant — ingest company handbooks and processes What I Learned Offline AI is production-ready. Foundry Local + small models like Phi-3.5 Mini are genuinely useful for focused tasks. You don't need vector databases for small collections. SQLite + TF-IDF is fast, simple, and has zero infrastructure overhead. RAG quality depends on chunking. Getting chunk sizes right for your use case is more impactful than the retrieval algorithm. The OpenAI-compatible API is a game-changer. Switching from cloud to local was mostly just changing the baseURL . Dual interfaces are easy when you share the engine. The CLI and Web UI are thin layers over the same ChatEngine class. ⚡ Performance Notes On a typical laptop (no GPU): ingestion takes under 1 second for ~20 documents, retrieval is ~1ms, and the first LLM token arrives in 2-5 seconds. Foundry Local automatically selects the best model variant for your hardware (CUDA GPU, NPU, or CPU).

A hands-on guide to building real-world AI automation with Foundry Local, the Microsoft Agent Framework, and PyBullet. No cloud subscription, no API keys, no internet required. Why Developers Should Care About Offline AI Imagine telling a robot arm to "pick up the cube" and watching it execute the command in a physics simulator, all powered by a language model running on your laptop. No API calls leave your machine. No token costs accumulate. No internet connection is needed. That is what this project delivers, and every piece of it is open source and ready for you to fork, extend, and experiment with. Most AI demos today lean on cloud endpoints. That works for prototypes, but it introduces latency, ongoing costs, and data privacy concerns. For robotics and industrial automation, those trade-offs are unacceptable. You need inference that runs where the hardware is: on the factory floor, in the lab, or on your development machine. Foundry Local gives you an OpenAI-compatible endpoint running entirely on-device. Pair it with a multi-agent orchestration framework and a physics engine, and you have a complete pipeline that translates natural language into validated, safe robot actions. This post walks through how we built it, why the architecture works, and how you can start experimenting with your own offline AI simulators today. Architecture The system uses four specialised agents orchestrated by the Microsoft Agent Framework: Agent What It Does Speed PlannerAgent Sends user command to Foundry Local LLM → JSON action plan 4–45 s SafetyAgent Validates against workspace bounds + schema < 1 ms ExecutorAgent Dispatches actions to PyBullet (IK, gripper) < 2 s NarratorAgent Template summary (LLM opt-in via env var) < 1 ms User (text / voice) │ ▼ ┌──────────────┐ │ Orchestrator │ └──────┬───────┘ │ ┌────┴────┐ ▼ ▼ Planner Narrator │ ▼ Safety │ ▼ Executor │ ▼ PyBullet Setting Up Foundry Local from foundry_local import FoundryLocalManager import openai manager = FoundryLocalManager("qwen2.5-coder-0.5b") client = openai.OpenAI( base_url=manager.endpoint, api_key=manager.api_key, ) resp = client.chat.completions.create( model=manager.get_model_info("qwen2.5-coder-0.5b").id, messages=[{"role": "user", "content": "pick up the cube"}], max_tokens=128, stream=True, ) from foundry_local import FoundryLocalManager import openai manager = FoundryLocalManager("qwen2.5-coder-0.5b") client = openai.OpenAI( base_url=manager.endpoint, api_key=manager.api_key, ) resp = client.chat.completions.create( model=manager.get_model_info("qwen2.5-coder-0.5b").id, messages=[{"role": "user", "content": "pick up the cube"}], max_tokens=128, stream=True, ) The SDK auto-selects the best hardware backend (CUDA GPU → QNN NPU → CPU). No configuration needed. How the LLM Drives the Simulator Understanding the interaction between the language model and the physics simulator is central to the project. The two never communicate directly. Instead, a structured JSON contract forms the bridge between natural language and physical motion. From Words to JSON When a user says “pick up the cube”, the PlannerAgent sends the command to the Foundry Local LLM alongside a compact system prompt. The prompt lists every permitted tool and shows the expected JSON format. The LLM responds with a structured plan: { "type": "plan", "actions": [ {"tool": "describe_scene", "args": {}}, {"tool": "pick", "args": {"object": "cube_1"}} ] } The planner parses this response, validates it against the action schema, and retries once if the JSON is malformed. This constrained output format is what makes small models (0.5B parameters) viable: the response space is narrow enough that even a compact model can produce correct JSON reliably. From JSON to Motion Once the SafetyAgent approves the plan, the ExecutorAgent maps each action to concrete PyBullet calls: move_ee(target_xyz) : The target position in Cartesian coordinates is passed to PyBullet's inverse kinematics solver, which computes the seven joint angles needed to place the end-effector at that position. The robot then interpolates smoothly from its current joint state to the target, stepping the physics simulation at each increment. pick(object) : This triggers a multi-step grasp sequence. The controller looks up the object's position in the scene, moves the end-effector above the object, descends to grasp height, closes the gripper fingers with a configurable force, and lifts. At every step, PyBullet resolves contact forces and friction so that the object behaves realistically. place(target_xyz) : The reverse of a pick. The robot carries the grasped object to the target coordinates and opens the gripper, allowing the physics engine to drop the object naturally. describe_scene() : Rather than moving the robot, this action queries the simulation state and returns the position, orientation, and name of every object on the table, along with the current end-effector pose. The Abstraction Boundary The critical design choice is that the LLM knows nothing about joint angles, inverse kinematics, or physics. It operates purely at the level of high-level tool calls ( pick , move_ee ). The ActionExecutor translates those tool calls into the low-level API that PyBullet provides. This separation means the LLM prompt stays simple, the safety layer can validate plans without understanding kinematics, and the executor can be swapped out without retraining or re-prompting the model. Voice Input Pipeline Voice commands follow three stages: Browser capture: MediaRecorder captures audio, client-side resamples to 16 kHz mono WAV Server transcription: Foundry Local Whisper (ONNX, cached after first load) with automatic 30 s chunking Command execution: transcribed text goes through the same Planner → Safety → Executor pipeline The mic button (🎤) only appears when a Whisper model is cached or loaded. Whisper models are filtered out of the LLM dropdown.

Launch the web UI python -m src.app --web --no-gui # → http://localhost:8080 Once the server starts, open your browser and try these commands in the chat box: "pick up the cube": the robot grasps the blue cube and lifts it "describe the scene": returns every object's name and position "move to 0.3 0.2 0.5": sends the end-effector to specific coordinates "reset": returns the arm to its neutral pose If you have a microphone connected, hold the mic button and speak your command instead of typing. Voice input uses a local Whisper model, so your audio never leaves the machine. Experiment and Build Your Own The project is deliberately simple so that you can modify it quickly. Here are some ideas to get started. Add a new robot action The robot currently understands seven tools. Adding an eighth takes four steps: Define the schema in TOOL_SCHEMAS ( src/brain/action_schema.py ). Write a _do_<tool> handler in src/executor/action_executor.py . Register it in ActionExecutor._dispatch . Add a test in tests/test_executor.py . For example, you could add a rotate_ee tool that spins the end-effector to a given roll/pitch/yaw without changing position. Add a new agent Every agent follows the same pattern: an async run(context) method that reads from and writes to a shared dictionary. Create a new file in src/agents/ , register it in orchestrator.py , and the pipeline will call it in sequence. Ideas for new agents: VisionAgent: analyse a camera frame to detect objects and update the scene state before planning. CostEstimatorAgent: predict how many simulation steps an action plan will take and warn the user if it is expensive. ExplanationAgent: generate a step-by-step natural language walkthrough of the plan before execution, allowing the user to approve or reject it. Swap the LLM python -m src.app --web --model phi-4-mini Or use the model dropdown in the web UI; no restart is needed. Try different models and compare accuracy against inference speed. Smaller models are faster but may produce malformed JSON more often. Larger models are more accurate but slower. The retry logic in the planner compensates for occasional failures, so even a small model works well in practice. Swap the simulator PyBullet is one option, but the architecture does not depend on it. You could replace the simulation layer with: MuJoCo: a high-fidelity physics engine popular in reinforcement learning research. Isaac Sim: NVIDIA's GPU-accelerated robotics simulator with photorealistic rendering. Gazebo: the standard ROS simulator, useful if you plan to move to real hardware through ROS 2. The only requirement is that your replacement implements the same interface as PandaRobot and GraspController . Build something completely different The pattern at the heart of this project (LLM produces structured JSON, safety layer validates, executor dispatches to a domain-specific engine) is not limited to robotics. You could apply the same architecture to: Home automation: "turn off the kitchen lights and set the thermostat to 19 degrees" translated into MQTT or Zigbee commands. Game AI: natural language control of characters in a game engine, with the safety agent preventing invalid moves. CAD automation: voice-driven 3D modelling where the LLM generates geometry commands for OpenSCAD or FreeCAD. Lab instrumentation: controlling scientific equipment (pumps, stages, spectrometers) via natural language, with the safety agent enforcing hardware limits. From Simulator to Real Robot One of the most common questions about projects like this is whether it could control a real robot. The answer is yes, and the architecture is designed to make that transition straightforward. What Stays the Same The entire upper half of the pipeline is hardware-agnostic: The LLM planner generates the same JSON action plans regardless of whether the target is simulated or physical. It has no knowledge of the underlying hardware. The safety agent validates workspace bounds and tool schemas. For a real robot, you would tighten the bounds to match the physical workspace and add checks for obstacle clearance using sensor data. The orchestrator coordinates agents in the same sequence. No changes are needed. The narrator reports what happened. It works with any result data the executor returns. What Changes The only component that must be replaced is the executor layer, specifically the PandaRobot class and the GraspController . In simulation, these call PyBullet's inverse kinematics solver and step the physics engine. On a real robot, they would instead call the hardware driver. For a Franka Emika Panda (the same robot modelled in the simulation), the replacement options include: libfranka: Franka's C++ real-time control library, which accepts joint position or torque commands at 1 kHz. ROS 2 with MoveIt: A robotics middleware stack that provides motion planning, collision avoidance, and hardware abstraction. The move_ee action would become a MoveIt goal, and the framework would handle trajectory planning and execution. Franka ROS 2 driver: Combines libfranka with ROS 2 for a drop-in replacement of the simulation controller. The ActionExecutor._dispatch method maps tool names to handler functions. Replacing _do_move_ee , _do_pick , and _do_place with calls to a real robot driver is the only code change required. Key Considerations for Real Hardware Safety: A simulated robot cannot cause physical harm; a real robot can. The safety agent would need to incorporate real-time collision checking against sensor data (point clouds from depth cameras, for example) rather than relying solely on static workspace bounds. Perception: In simulation, object positions are known exactly. On a real robot, you would need a perception system (cameras with object detection or fiducial markers) to locate objects before grasping. Calibration: The simulated robot's coordinate frame matches the URDF model perfectly. A real robot requires hand-eye calibration to align camera coordinates with the robot's base frame. Latency: Real actuators have physical response times. The executor would need to wait for motion completion signals from the hardware rather than stepping a simulation loop. Gripper feedback: In PyBullet, grasp success is determined by contact forces. A real gripper would provide force or torque feedback to confirm whether an object has been securely grasped. The Simulation as a Development Tool This is precisely why simulation-first development is valuable. You can iterate on the LLM prompts, agent logic, and command pipeline without risk to hardware. Once the pipeline reliably produces correct action plans in simulation, moving to a real robot is a matter of swapping the lowest layer of the stack. Key Takeaways for Developers On-device AI is production-ready. Foundry Local serves models through a standard OpenAI-compatible API. If your code already uses the OpenAI SDK, switching to local inference is a one-line change to base_url . Small models are surprisingly capable. A 0.5B parameter model produces valid JSON action plans in under 5 seconds. For constrained output schemas, you do not need a 70B model. Multi-agent pipelines are more reliable than monolithic prompts. Splitting planning, validation, execution, and narration across four agents makes each one simpler to test, debug, and replace. Simulation is the safest way to iterate. You can refine LLM prompts, agent logic, and tool schemas without risking real hardware. When the pipeline is reliable, swapping the executor for a real robot driver is the only change needed. The pattern generalises beyond robotics. Structured JSON output from an LLM, validated by a safety layer, dispatched to a domain-specific engine: that pattern works for home automation, game AI, CAD, lab equipment, and any other domain where you need safe, structured control. You can start building today. The entire project runs on a standard laptop with no GPU, no cloud account, and no API keys. Clone the repository, run the setup script, and you will have a working voice-controlled robot simulator in under five minutes. Ready to start building? Clone the repository, try the commands, and then start experimenting. Fork it, add your own agents, swap in a different simulator, or apply the pattern to an entirely different domain.

From “waiting” to “instant”- without sending data away AI is everywhere, but speed, privacy, and reliability are critical. Users expect instant answers without compromise. On-device AI makes that possible: fast, private and available, even when the network isn’t - empowering apps to deliver seamless experiences. Imagine an intelligent assistant that works in seconds, without sending a text to the cloud. This approach brings speed and data control to the places that need it most; while still letting you tap into cloud power when it makes sense. Windows AI Foundry: A Local Home for Models Windows AI Foundry is a developer toolkit that makes it simple to run AI models directly on Windows devices. It uses ONNX Runtime under the hood and can leverage CPU, GPU (via DirectML), or NPU acceleration, without requiring you to manage those details. The principle is straightforward: Keep the model and the data on the same device. Inference becomes faster, and data stays local by default unless you explicitly choose to use the cloud. Foundry Local Foundry Local is the engine that powers this experience. Think of it as local AI runtime - fast, private, and easy to integrate into an app. Why Adopt On‑Device AI? Faster, more responsive apps: Local inference often reduces perceived latency and improves user experience. Privacy‑first by design: Keep sensitive data on the device; avoid cloud round trips unless the user opts in. Offline capability: An app can provide AI features even without a network connection. Cost control: Reduce cloud compute and data costs for common, high‑volume tasks. This approach is especially useful in regulated industries, field‑work tools, and any app where users expect quick, on‑device responses. Hybrid Pattern for Real Apps On-device AI doesn’t replace the cloud, it complements it. Here’s how: Standalone On‑Device: Quick, private actions like document summarization, local search, and offline assistants. Cloud‑Enhanced (Optional): Large-context models, up-to-date knowledge, or heavy multimodal workloads. Design an app to keep data local by default and surface cloud options transparently with user consent and clear disclosures. Windows AI Foundry supports hybrid workflows: Use Foundry Local for real-time inference. Sync with Azure AI services for model updates, telemetry, and advanced analytics. Implement fallback strategies for resource-intensive scenarios. Application Workflow Code Example using Foundry Local: 1. Only On-Device: Tries Foundry Local first, falls back to ONNX if foundry_runtime.check_foundry_available(): # Use on-device Foundry Local models try: answer = foundry_runtime.run_inference(question, context) return answer, source="Foundry Local (On-Device)" except Exception as e: logger.warning(f"Foundry failed: {e}, trying ONNX...") if onnx_model.is_loaded(): # Fallback to local BERT ONNX model try: answer = bert_model.get_answer(question, context) return answer, source="BERT ONNX (On-Device)" except Exception as e: logger.warning(f"ONNX failed: {e}") return "Error: No local AI available" 2. Hybrid approach: On-device first, cloud as last resort def get_answer(question, context): """ Priority order: 1. Foundry Local (best: advanced + private) 2. ONNX Runtime (good: fast + private) 3. Cloud API (fallback: requires internet, less private) # in case of Hybrid approach, based on real-time scenario """ if foundry_runtime.check_foundry_available(): # Use on-device Foundry Local models try: answer = foundry_runtime.run_inference(question, context) return answer, source="Foundry Local (On-Device)" except Exception as e: logger.warning(f"Foundry failed: {e}, trying ONNX...") if onnx_model.is_loaded(): # Fallback to local BERT ONNX model try: answer = bert_model.get_answer(question, context) return answer, source="BERT ONNX (On-Device)" except Exception as e: logger.warning(f"ONNX failed: {e}, trying cloud...") # Last resort: Cloud API (requires internet) if network_available(): try: import requests response = requests.post( '{BASE_URL_AI_CHAT_COMPLETION}', headers={'Authorization': f'Bearer {API_KEY}'}, json={ 'model': '{MODEL_NAME}', 'messages': [{ 'role': 'user', 'content': f'Context: {context}\n\nQuestion: {question}' }] }, timeout=10 ) answer = response.json()['choices'][0]['message']['content'] return answer, source="Cloud API (Online)" except Exception as e: return "Error: No AI runtime available", source="Failed" else: return "Error: No internet and no local AI available", source="Offline" Demo Project Output: Foundry Local answering context-based questions offline : The Foundry Local engine ran the Phi-4-mini model offline and retrieved context-based data. : The Foundry Local engine ran the Phi-4-mini model offline and mentioned that there is no answer. Practical Use Cases Privacy-First Reading Assistant: Summarize documents locally without sending text to the cloud. Healthcare Apps: Analyze medical data on-device for compliance.

Introduction Are you tired of watching your AI application costs spiral out of control every time your user base grows? As AI Engineers and Developers, we've all felt the pain of cloud-dependent LLM deployments. Every API call adds up, latency becomes a bottleneck in real-time applications, and sensitive data must leave your infrastructure to get processed. Meanwhile, your users demand faster responses, better privacy, and more reliable service. What if there was a way to run powerful language models directly on your users' devices or your local infrastructure? Enter the world of Edge AI deployment with Microsoft's Foundry Local a game-changing approach that brings enterprise-grade LLM capabilities to local hardware while maintaining full OpenAI API compatibility. The Edge AI for Beginners https://aka.ms/edgeai-for-beginners curriculum provides AI Engineers and Developers with comprehensive, hands-on training to master local LLM deployment. This isn't just another theoretical course, it's a practical guide that will transform how you think about AI infrastructure, combining cutting-edge local deployment techniques with production-ready implementation patterns. In this post, we'll explore why Edge AI deployment represents the future of AI applications, dive deep into Foundry Local's capabilities across multiple frameworks, and show you exactly how to implement local LLM solutions that deliver both technical excellence and significant business value. Why Edge AI Deployment Changes Everything for Developers The shift from cloud-dependent to edge-deployed AI represents more than just a technical evolution, it's a fundamental reimagining of how we build intelligent applications. As AI Engineers, we're witnessing a transformation that addresses the most pressing challenges in modern AI deployment while opening up entirely new possibilities for innovation. Consider the current state of cloud-based LLM deployment. Every user interaction requires a round-trip to external servers, introducing latency that can kill user experience in real-time applications. Costs scale linearly (or worse) with usage, making successful applications expensive to operate. Sensitive data must traverse networks and live temporarily in external systems, creating compliance nightmares for enterprise applications. Edge AI deployment fundamentally changes this equation. By running models locally, we achieve several critical advantages: Data Sovereignty and Privacy Protection: Your sensitive data never leaves your infrastructure. For healthcare applications processing patient records, financial services handling transactions, or enterprise tools managing proprietary information, this represents a quantum leap in security posture. You maintain complete control over data flow, meeting even the strictest compliance requirements without architectural compromises. Real-Time Performance at Scale: Local inference eliminates network latency entirely. Instead of 200-500ms round-trips to cloud APIs, you get sub-10ms response times. This enables entirely new categories of applications—real-time code completion, interactive AI tutoring systems, voice assistants that respond instantly, and IoT devices that make intelligent decisions without connectivity. Predictable Cost Structure: Transform variable API costs into fixed infrastructure investments. Instead of paying per-token for potentially unlimited usage, you invest in local hardware that serves unlimited requests. This makes ROI calculations straightforward and removes the fear of viral success destroying your margins. Offline Capabilities and Resilience: Local deployment means your AI features work even when connectivity fails. Mobile applications can provide intelligent features in areas with poor network coverage. Critical systems maintain AI capabilities during network outages. Edge devices in remote locations operate autonomously. The technical implications extend beyond these obvious benefits. Local deployment enables new architectural patterns: AI-powered applications that work entirely client-side, edge computing nodes that make intelligent routing decisions, and distributed systems where intelligence lives close to data sources. Foundry Local: Multi-Framework Edge AI Deployment Made Simple Microsoft's Foundry Local https://www.foundrylocal.ai represents a breakthrough in local AI deployment, designed specifically for developers who need production-ready edge AI solutions. Unlike single-framework tools, Foundry Local provides a unified platform that works seamlessly across multiple programming languages and deployment scenarios while maintaining full compatibility with existing OpenAI-based workflows. The platform's approach to multi-framework support means you're not locked into a single technology stack. Whether you're building TypeScript applications, Python ML pipelines, Rust systems programming projects, or .NET enterprise applications, Foundry Local provides native SDKs and consistent APIs that integrate naturally with your existing codebase. Enterprise-Grade Model Catalog: Foundry Local comes with a curated selection of production-ready models optimized for edge deployment. The `phi-3.5-mini` model delivers impressive performance in a compact footprint, perfect for resource-constrained environments. For applications requiring more sophisticated reasoning, `qwen2.5-0.5b` provides enhanced capabilities while maintaining efficiency. When you need maximum capability and have sufficient hardware resources, `gpt-oss-20b` offers state-of-the-art performance with full local control. Intelligent Hardware Optimization: One of Foundry Local's most powerful features is its automatic hardware detection and optimization. The platform automatically identifies your available compute resources, NVIDIA CUDA GPUs, AMD GPUs, Intel NPUs, Qualcomm Snapdragon NPUs, or CPU-only environments and downloads the most appropriate model variant. This means the same application code delivers optimal performance across diverse hardware configurations without manual intervention. ONNX Runtime Acceleration: Under the hood, Foundry Local leverages Microsoft's ONNX Runtime for maximum performance. This provides significant advantages over generic inference engines, delivering optimized execution paths for different hardware architectures while maintaining model accuracy and compatibility. OpenAI SDK Compatibility: Perhaps most importantly for developers, Foundry Local maintains complete API compatibility with the OpenAI SDK. This means existing applications can migrate to local inference by changing only the endpoint configuration—no rewriting of application logic, no learning new APIs, no disruption to existing workflows. The platform handles the complex aspects of local AI deployment automatically: model downloading, hardware-specific optimization, memory management, and inference scheduling. This allows developers to focus on building intelligent applications rather than managing AI infrastructure. Framework-Agnostic Benefits: Foundry Local's multi-framework approach delivers consistent benefits regardless of your technology choices. Whether you're working in a Node.js microservices architecture, a Python data science environment, a Rust embedded system, or a C# enterprise application, you get the same advantages: reduced latency, eliminated API costs, enhanced privacy, and offline capabilities. This universal compatibility means teams can adopt edge AI deployment incrementally, starting with pilot projects in their preferred language and expanding across their technology stack as they see results. The learning curve is minimal because the API patterns remain familiar while the underlying infrastructure transforms to local deployment. Implementing Edge AI: From Code to Production Moving from cloud APIs to local AI deployment requires understanding the implementation patterns that make edge AI both powerful and practical. Let's explore how Foundry Local's SDKs enable seamless integration across different development environments, with real-world code examples that you can adapt for your production systems. Python Implementation for Data Science and ML Pipelines Python developers will find Foundry Local's integration particularly natural, especially in data science and machine learning contexts where local processing is often preferred for security and performance reasons. import openai from foundry_local import FoundryLocalManager # Initialize with automatic hardware optimization alias = "phi-3.5-mini" manager = FoundryLocalManager(alias) This simple initialization handles a remarkable amount of complexity automatically. The `FoundryLocalManager` detects your hardware configuration, downloads the most appropriate model variant for your system, and starts the local inference service. Behind the scenes, it's making intelligent decisions about memory allocation, selecting optimal execution providers, and preparing the model for efficient inference. # Configure OpenAI client for local deployment client = openai.OpenAI( base_url=manager.endpoint, api_key=manager.api_key # Not required for local, but maintains API compatibility ) # Production-ready inference with streaming def analyze_document(content: str): stream = client.chat.completions.create( model=manager.get_model_info(alias).id, messages=[{ "role": "system", "content": "You are an expert document analyzer. Provide structured analysis." }, { "role": "user", "content": f"Analyze this document: {content}" }], stream=True, temperature=0.7 ) result = "" for chunk in stream: if chunk.choices[0].delta.content: content_piece = chunk.choices[0].delta.content result += content_piece yield content_piece # Enable real-time UI updates return result Key implementation benefits here: • Automatic model management: The `FoundryLocalManager` handles model lifecycle, memory optimization, and hardware-specific acceleration without manual configuration. • Streaming interface compatibility: Maintains the familiar OpenAI streaming API while processing locally, enabling real-time user interfaces with zero latency overhead. • Production error handling: The manager includes built-in retry logic, graceful degradation, and resource management for reliable production deployment. JavaScript/TypeScript Implementation for Web Applications JavaScript and TypeScript developers can integrate local AI capabilities directly into web applications, enabling entirely new categories of client-side intelligent features. import { OpenAI } from "openai"; import { FoundryLocalManager } from "foundry-local-sdk"; class LocalAIService { constructor() { this.foundryManager = null; this.openaiClient = null; this.isInitialized = false; } async initialize(modelAlias = "phi-3.5-mini") { this.foundryManager = new FoundryLocalManager(); const modelInfo = await this.foundryManager.init(modelAlias); this.openaiClient = new OpenAI({ baseURL: this.foundryManager.endpoint, apiKey: this.foundryManager.apiKey, }); this.isInitialized = true; return modelInfo; } The initialization pattern establishes local AI capabilities with full error handling and resource management. This enables web applications to provide AI features without external API dependencies. async generateCodeCompletion(codeContext, userPrompt) { if (!this.isInitialized) { throw new Error("LocalAI service not initialized"); } try { const completion = await this.openaiClient.chat.completions.create({ model: this.foundryManager.getModelInfo().id, messages: [ { role: "system", content: "You are a code completion assistant. Provide accurate, efficient code suggestions." }, { role: "user", content: `Context: ${codeContext}\n\nComplete: ${userPrompt}` } ], max_tokens: 150, temperature: 0.2 }); return completion.choices[0].message.content; } catch (error) { console.error("Local AI completion failed:", error); throw new Error("Code completion unavailable"); } } } Implementation advantages for web applications • Zero-dependency AI features: Applications work entirely offline once models are downloaded, enabling AI capabilities in disconnected environments. • Instant response times: Eliminate network latency for real-time features like code completion, content generation, or intelligent search. • Client-side privacy: Sensitive code or content never leaves the user's device, meeting strict security requirements for enterprise development tools. Cross-Platform Production Deployment Patterns Both Python and JavaScript implementations share common production deployment patterns that make Foundry Local particularly suitable for enterprise applications: Automatic Hardware Optimization: The platform automatically detects and utilizes available acceleration hardware. On systems with NVIDIA GPUs, it leverages CUDA acceleration. On newer Intel systems, it uses NPU acceleration. On ARM-based systems like Apple Silicon or Qualcomm Snapdragon, it optimizes for those architectures. This means the same application code delivers optimal performance across diverse deployment environments. Graceful Resource Management: Foundry Local includes sophisticated memory management and resource allocation. Models are loaded efficiently, memory is recycled properly, and concurrent requests are handled intelligently to maintain system stability under load. Production Monitoring Integration: The platform provides comprehensive metrics and logging that integrate naturally with existing monitoring systems, enabling production observability for AI workloads running at the edge. These implementation patterns demonstrate how Foundry Local transforms edge AI from an experimental concept into a practical, production-ready deployment strategy that works consistently across different technology stacks and hardware environments. Measuring Success: Technical Performance and Business Impact The transition to edge AI deployment delivers measurable improvements across both technical and business metrics. Understanding these impacts helps justify the architectural shift and demonstrates the concrete value of local LLM deployment in production environments. Technical Performance Gains Latency Elimination: The most immediately visible benefit is the dramatic reduction in response times. Cloud API calls typically require 200-800ms round-trips, depending on geographic location and network conditions. Local inference with Foundry Local reduces this to sub-10ms response times—a 95-99% improvement that fundamentally changes user experience possibilities. Consider a code completion feature: cloud-based completion feels sluggish and interrupts developer flow, while local completion provides instant suggestions that enhance productivity. The same applies to real-time chat applications, interactive AI tutoring systems, and any application where response latency directly impacts usability. Automatic Hardware Utilization: Foundry Local's intelligent hardware detection and optimization delivers significant performance improvements without manual configuration. On systems with NVIDIA RTX 4000 series GPUs, inference speeds can be 10-50x faster than CPU-only processing. On newer Intel systems with NPUs, the platform automatically leverages neural processing units for efficient AI workloads. Apple Silicon systems benefit from Metal Performance Shaders optimization, delivering excellent performance per watt. ONNX Runtime Optimization: Microsoft's ONNX Runtime provides substantial performance advantages over generic inference engines. In benchmark testing, ONNX Runtime consistently delivers 2-5x performance improvements compared to standard PyTorch or TensorFlow inference, while maintaining full model accuracy and compatibility. Scalability Characteristics: Local deployment transforms scaling economics entirely. Instead of linear cost scaling with usage, you get horizontal scaling through hardware deployment. A single modern GPU can handle hundreds of concurrent inference requests, making per-request costs approach zero for high-volume applications. Business Impact Analysis Cost Structure Transformation: The financial implications of local deployment are profound. Consider an application processing 1 million tokens daily through OpenAI's API—this represents $20-60 in daily costs depending on the model. Over a year, this becomes $7,300-21,900 in recurring expenses. A comparable local deployment might require a $2,000-5,000 hardware investment with no ongoing API costs. For high-volume applications, the savings become dramatic. Applications processing 100 million tokens monthly face $60,000-180,000 annual API costs. Local deployment with appropriate hardware infrastructure could reduce this to electricity and maintenance costs—typically under $10,000 annually for equivalent processing capacity. Enhanced Privacy and Compliance: Local deployment eliminates data sovereignty concerns entirely. Healthcare applications processing patient records, financial services handling transaction data, and enterprise tools managing proprietary information can deploy AI capabilities without data leaving their infrastructure. This simplifies compliance with GDPR, HIPAA, SOX, and other regulatory frameworks while reducing legal and security risks. Operational Resilience: Local deployment provides significant business continuity advantages. Applications continue functioning during network outages, API service disruptions, or third-party provider issues. For mission-critical systems, this resilience can prevent costly downtime and maintain user productivity during external service failures. Development Velocity: Local deployment accelerates development cycles by eliminating API rate limits, usage quotas, and external dependencies during development and testing. Developers can iterate freely, run comprehensive test suites, and experiment with AI features without cost concerns or rate limiting delays. Enterprise Adoption Metrics Real-world enterprise deployments demonstrate measurable business value: Local Usage: Foundry Local for internal AI-powered tools, reporting 60-80% reduction in AI-related operational costs while improving developer productivity through instant AI responses in development environments. Manufacturing Applications: Industrial IoT deployments using edge AI for predictive maintenance show 40-60% reduction in unplanned downtime while eliminating cloud connectivity requirements in remote facilities. Financial Services: Trading firms deploying local LLMs for market analysis report sub-millisecond decision latencies while maintaining complete data isolation for competitive advantage and regulatory compliance. ROI Calculation Framework For AI Engineers evaluating edge deployment, consider these quantifiable factors: Direct Cost Savings: Compare monthly API costs against hardware amortization over 24-36 months. Most applications with >$1,000 monthly API costs achieve positive ROI within 12-18 months. Performance Value: Quantify the business impact of reduced latency. For customer-facing applications, each 100ms of latency reduction typically correlates with 1-3% conversion improvement. Risk Mitigation: Calculate the cost of downtime or compliance violations prevented by local deployment. For many enterprise applications, avoiding a single significant outage justifies the infrastructure investment. Development Efficiency: Measure developer productivity improvements from unlimited local AI access during development. Teams report 20-40% faster iteration cycles when AI features can be tested without external dependencies. These metrics demonstrate that edge AI deployment with Foundry Local delivers both immediate technical improvements and substantial long-term business value, making it a strategic investment in AI infrastructure that pays dividends across multiple dimensions.

We are excited to introduce AI Travel Agents, a sample application with enterprise functionality that demonstrates how developers can coordinate multiple AI agents (written in multiple languages) to explore travel planning scenarios. It's built with LlamaIndex.TS for agent orchestration, Model Context Protocol (MCP) for structured tool interactions, and Azure Container Apps for scalable deployment. TL;DR: Experience the power of MCP and Azure Container Apps with The AI Travel Agents! Try out live demo locally on your computer for free to see real-time agent collaboration in action. Share your feedback on our community forum. We’re already planning enhancements, like new MCP-integrated agents, enabling secure communication between the AI agents and MCP servers and more. NOTE: This example uses mock data and is intended for demonstration purposes rather than production use. The Challenge: Scaling Personalized Travel Planning Travel agencies grapple with complex tasks: analyzing diverse customer needs, recommending destinations, and crafting itineraries, all while integrating real-time data like trending spots or logistics. Traditional systems falter with latency, scalability, and coordination, leading to delays and frustrated clients. The AI Travel Agents tackles these issues with a technical trifecta: LlamaIndex.TS orchestrates six AI agents for efficient task handling. MCP equips agents with travel-specific data and tools. Azure Container Apps ensures scalable, serverless deployment. This architecture delivers operational efficiency and personalized service at scale, transforming chaos into opportunity. LlamaIndex.TS: Orchestrating AI Agents The heart of The AI Travel Agents is LlamaIndex.TS, a powerful agentic framework that orchestrates multiple AI agents to handle travel planning tasks. Built on a Node.js backend, LlamaIndex.TS manages agent interactions in a seamless and intelligent manner: Task Delegation: The Triage Agent analyzes queries and routes them to specialized agents, like the Itinerary Planning Agent, ensuring efficient workflows. Agent Coordination: LlamaIndex.TS maintains context across interactions, enabling coherent responses for complex queries, such as multi-city trip plans. LLM Integration: Connects to Azure OpenAI, GitHub Models or any local LLM using Foundy Local for advanced AI capabilities. LlamaIndex.TS’s modular design supports extensibility, allowing new agents to be added with ease. LlamaIndex.TS is the conductor, ensuring agents work in sync to deliver accurate, timely results. Its lightweight orchestration minimizes latency, making it ideal for real-time applications. MCP: Fueling Agents with Data and Tools The Model Context Protocol (MCP) empowers AI agents by providing travel-specific data and tools, enhancing their functionality. MCP acts as a data and tool hub: Real-Time Data: Supplies up-to-date travel information, such as trending destinations or seasonal events, via the Web Search Agent using Bing Search. Tool Access: Connects agents to external tools, like the .NET-based customer queries analyzer for sentiment analysis, the Python-based itinerary planning for trip schedules or destination recommendation tools written in Java. For example, when the Destination Recommendation Agent needs current travel trends, MCP delivers via the Web Search Agent. This modularity allows new tools to be integrated seamlessly, future-proofing the platform. MCP’s role is to enrich agent capabilities, leaving orchestration to LlamaIndex.TS. Azure Container Apps: Scalability and Resilience Azure Container Apps powers The AI Travel Agents sample application with a serverless, scalable platform for deploying microservices. It ensures the application handles varying workloads with ease: Dynamic Scaling: Automatically adjusts container instances based on demand, managing booking surges without downtime.

Observability: Integrates tracing, metrics, and logging enabling real-time monitoring. Serverless Efficiency: Abstracts infrastructure, reducing costs and accelerating deployment. Azure Container Apps' global infrastructure delivers low-latency performance, critical for travel agencies serving clients worldwide. The AI Agents: A Quick Look While MCP and Azure Container Apps are the stars, they support a team of multiple AI agents that drive the application’s functionality. Built and orchestrated with Llamaindex.TS via MCP, these agents collaborate to handle travel planning tasks: Triage Agent: Directs queries to the right agent, leveraging MCP for task delegation. Customer Query Agent: Analyzes customer needs (emotions, intents), using .NET tools. Destination Recommendation Agent: Suggests tailored destinations, using Java. Itinerary Planning Agent: Crafts efficient itineraries, powered by Python. Web Search Agent: Fetches real-time data via Bing Search. These agents rely on MCP’s real-time communication and Azure Container Apps’ scalability to deliver responsive, accurate results. It's worth noting though this sample application uses mock data for demonstration purpose. In real worl scenario, the application would communicate with an MCP server that is plugged in a real production travel API.

In situations with limited computing, Phi-4-mini-reasoning will is an excellent model choice. We can use Microsoft Olive or Apple MLX Framework to quantize Phi-4-mini-reasoning and deploy it on edge terminals such as IoT, Laotop and mobile devices. Quantization In order to solve the problem that the model is difficult to deploy directly to specific hardware, we need to reduce the complexity of the model through model quantization. Undertaking the quantization process will inevitably cause precision loss. Quantize Phi-4-mini-reasoning using Microsoft Olive Microsoft Olive is an AI model optimization toolkit for ONNX Runtime. Given a model and target hardware, Olive (short for Onnx LIVE) will combine the most appropriate optimization techniques to output the most efficient ONNX model for inference in the cloud or on the edge. We can combine Microsoft Olive and Phi-4-mini-reasoning on Azure AI Foundry's Model Catalog to quantize Phi-4-mini-reasoning to an ONNX format model.

Join our Microsoft Azure AI Foundry Discord channel to continue the discussion 🚀Selecting and upgrading models using Evaluations – Part 2
In the previous article, we explored why evaluations are crucial and how they can help you choose the right model for your specific industry, domain, or app-level data. We also introduced the "bulk-run" feature in AI Toolkit for Visual Studio Code, which allows you to automate parts of the human evaluation process. In this article, we'll take things a step further by using a more capable model to evaluate the responses of a less capable one. For example, you might compare older versions of a model against a newer, more powerful version, or evaluate a fine-tuned small language model (SLM) using a larger model like GPT-4o. You can access this functionality through the "Evaluations" option in the tool's menu of the AI Toolkit for Visual Studio Code Extension (see below). But before we start using it, let’s take a moment to understand the distinct types of evaluation methods available for assessing responses from large language models. Evaluators When testing AI models, it's not enough to just look at outputs manually. Evaluators help us systematically measure how well a model is performing across different dimensions like relevance, coherence and fluency, these specific metrics include grammar, similarity to ground truth and more. Below is a brief overview of the key evaluators commonly used: Coherence - Evaluates how naturally and logically a model’s response flows. It checks whether the answer makes sense in context and follows a consistent train of thought. Required columns: query, response Fluency - Assesses grammatical correctness and fluency. A fluent response reads smoothly, like something a human would write. Required columns: response Relevance - Checks how well the response answers the original question or prompt. It’s all about staying on topic and being helpful. Required columns: query, response Similarity - Measures how similar the model’s response is to a reference (ground truth), taking both the question and answer into account. Required columns: query, response, ground_truth BLEU (Bilingual Evaluation Understudy) - A popular metric that compares how closely the model’s output matches reference texts using n-gram overlaps. Required columns: response, ground_truth F1 Score - Calculates the overlap of words between the model’s output and the correct answer, balancing precision and recall. Required columns: response, ground_truth GLEU (General Language Understanding Benchmark) - Similar to BLEU but optimized for sentence-level evaluation. It uses n-gram overlap to assess how well the output matches the reference. Required columns: response, ground_truth METEOR - Goes beyond simple word overlap by aligning synonyms and related phrases, while also focusing on precision, recall, and word order. Required columns: response, ground_truth Using Evaluations Now that we have an overview of the evaluations, let’s use a sample dataset to run an evaluation. Open Visual Studio Code and select the AI Toolkit Extension, in the AI Toolkit extension: Click on the Tools Menu > Eval the Tools Menu > Evaluations and you should get a window like below: You can either create a new evaluation or create a new evaluation run (See the blue button on the top right of the screen). If you create a new evaluation, you can choose one or more of the evaluators we talked about above. You can use the sample dataset, or you can use your own dataset. Just be aware, that if you are running a large dataset of your own, you might run against the rate limit for GitHub models, if you choose those for evaluating the output. You can create your own dataset in the JSONLines format we discussed in the earlier part of this blog post. In addition to using your own dataset to evaluate the model, you can also use your own python evaluators. Click on the evaluators tab and you should see the following screen. Using the Create Evaluation button (highlighted in blue on the top right-hand corner of the pane), you can create and add your own evaluator. The fields are self-explanatory. Evaluation run Let's now run the evaluation and you should see something like the output below. You can see the line-by-line input (from the JSONLines dataset that you used) and output against each of the evaluators that you have selected. You can also see the details of the run in the output pane below as the evaluations run. You will see each evaluation start (once per evaluator) and run through each of lines in your dataset. You might also see some errors sometimes due to rate limiting and which can be retried automatically by AI toolkit executor. You can see the scores for each of the evaluators by scrolling horizontally. You can additionally back up and check these scores using human evaluations as well, if necessary, especially for fields where domain expertise is important and the risk of harm due to errors is higher. Evaluations play a key role in understanding, selecting models and improving model performance across tasks and domains. By using a mix of automated and human-in-the-loop evaluators, you can get a clearer picture of your model's strengths and weaknesses. Start small, measure often, and let the data guide your AI application iterations.
