Integrating Microsoft Foundry with OpenClaw: Step by Step Model Configuration
Step 1: Deploying Models on Microsoft Foundry Let us kick things off in the Azure portal. To get our OpenClaw agent thinking like a genius, we need to deploy our models in Microsoft Foundry. For this guide, we are going to focus on deploying gpt-5.2-codex on Microsoft Foundry with OpenClaw. Navigate to your AI Hub, head over to the model catalog, choose the model you wish to use with OpenClaw and hit deploy. Once your deployment is successful, head to the endpoints section. Important: Grab your Endpoint URL and your API Keys right now and save them in a secure note. We will need these exact values to connect OpenClaw in a few minutes. Step 2: Installing and Initializing OpenClaw Next up, we need to get OpenClaw running on your machine. Open up your terminal and run the official installation script: curl -fsSL https://openclaw.ai/install.sh | bash The wizard will walk you through a few prompts. Here is exactly how to answer them to link up with our Azure setup: First Page (Model Selection): Choose "Skip for now". Second Page (Provider): Select azure-openai-responses. Model Selection: Select gpt-5.2-codex , For now only the models listed (hosted on Microsoft Foundry) in the picture below are available to be used with OpenClaw. Follow the rest of the standard prompts to finish the initial setup. Step 3: Editing the OpenClaw Configuration File Now for the fun part. We need to manually configure OpenClaw to talk to Microsoft Foundry. Open your configuration file located at ~/.openclaw/openclaw.json in your favorite text editor. Replace the contents of the models and agents sections with the following code block: { "models": { "providers": { "azure-openai-responses": { "baseUrl": "https://<YOUR_RESOURCE_NAME>.openai.azure.com/openai/v1", "apiKey": "<YOUR_AZURE_OPENAI_API_KEY>", "api": "openai-responses", "authHeader": false, "headers": { "api-key": "<YOUR_AZURE_OPENAI_API_KEY>" }, "models": [ { "id": "gpt-5.2-codex", "name": "GPT-5.2-Codex (Azure)", "reasoning": true, "input": ["text", "image"], "cost": { "input": 0, "output": 0, "cacheRead": 0, "cacheWrite": 0 }, "contextWindow": 400000, "maxTokens": 16384, "compat": { "supportsStore": false } }, { "id": "gpt-5.2", "name": "GPT-5.2 (Azure)", "reasoning": false, "input": ["text", "image"], "cost": { "input": 0, "output": 0, "cacheRead": 0, "cacheWrite": 0 }, "contextWindow": 272000, "maxTokens": 16384, "compat": { "supportsStore": false } } ] } } }, "agents": { "defaults": { "model": { "primary": "azure-openai-responses/gpt-5.2-codex" }, "models": { "azure-openai-responses/gpt-5.2-codex": {} }, "workspace": "/home/<USERNAME>/.openclaw/workspace", "compaction": { "mode": "safeguard" }, "maxConcurrent": 4, "subagents": { "maxConcurrent": 8 } } } } You will notice a few placeholders in that JSON. Here is exactly what you need to swap out: Placeholder Variable What It Is Where to Find It <YOUR_RESOURCE_NAME> The unique name of your Azure OpenAI resource. Found in your Azure Portal under the Azure OpenAI resource overview. <YOUR_AZURE_OPENAI_API_KEY> The secret key required to authenticate your requests. Found in Microsoft Foundry under your project endpoints or Azure Portal keys section. <USERNAME> Your local computer's user profile name. Open your terminal and type whoami to find this. Step 4: Restart the Gateway After saving the configuration file, you must restart the OpenClaw gateway for the new Foundry settings to take effect. Run this simple command: openclaw gateway restart Configuration Notes & Deep Dive If you are curious about why we configured the JSON that way, here is a quick breakdown of the technical details. Authentication Differences Azure OpenAI uses the api-key HTTP header for authentication. This is entirely different from the standard OpenAI Authorization: Bearer header. Our configuration file addresses this in two ways: Setting "authHeader": false completely disables the default Bearer header. Adding "headers": { "api-key": "<key>" } forces OpenClaw to send the API key via Azure's native header format. Important Note: Your API key must appear in both the apiKey field AND the headers.api-key field within the JSON for this to work correctly. The Base URL Azure OpenAI's v1-compatible endpoint follows this specific format: https://<your_resource_name>.openai.azure.com/openai/v1 The beautiful thing about this v1 endpoint is that it is largely compatible with the standard OpenAI API and does not require you to manually pass an api-version query parameter. Model Compatibility Settings "compat": { "supportsStore": false } disables the store parameter since Azure OpenAI does not currently support it. "reasoning": true enables the thinking mode for GPT-5.2-Codex. This supports low, medium, high, and xhigh levels. "reasoning": false is set for GPT-5.2 because it is a standard, non-reasoning model. Model Specifications & Cost Tracking If you want OpenClaw to accurately track your token usage costs, you can update the cost fields from 0 to the current Azure pricing. Here are the specs and costs for the models we just deployed: Model Specifications Model Context Window Max Output Tokens Image Input Reasoning gpt-5.2-codex 400,000 tokens 16,384 tokens Yes Yes gpt-5.2 272,000 tokens 16,384 tokens Yes No Current Cost (Adjust in JSON) Model Input (per 1M tokens) Output (per 1M tokens) Cached Input (per 1M tokens) gpt-5.2-codex $1.75 $14.00 $0.175 gpt-5.2 $2.00 $8.00 $0.50 Conclusion: And there you have it! You have successfully bridged the gap between the enterprise-grade infrastructure of Microsoft Foundry and the local autonomy of OpenClaw. By following these steps, you are not just running a chatbot; you are running a sophisticated agent capable of reasoning, coding, and executing tasks with the full power of GPT-5.2-codex behind it. The combination of Azure's reliability and OpenClaw's flexibility opens up a world of possibilities. Whether you are building an automated devops assistant, a research agent, or just exploring the bleeding edge of AI, you now have a robust foundation to build upon. Now it is time to let your agent loose on some real tasks. Go forth, experiment with different system prompts, and see what you can build. If you run into any interesting edge cases or come up with a unique configuration, let me know in the comments below. Happy coding!Now in Foundry: Qwen3-Coder-Next, Qwen3-ASR-1.7B, Z-Image

In this comprehensive guide, we'll explore how to integrate both Sora 1 and Sora 2 models from Azure OpenAI Service into a production web application. We'll cover API integration, request body parameters, cost analysis, limitations, and the key differences between using Azure AI Foundry endpoints versus OpenAI's native API. Table of Contents Introduction to Sora Models Azure AI Foundry vs. OpenAI API Structure API Integration: Request Body Parameters Video Generation Modes Cost Analysis per Generation Technical Limitations & Constraints Resolution & Duration Support Implementation Best Practices Introduction to Sora Models Sora is OpenAI's groundbreaking text-to-video model that generates realistic videos from natural language descriptions. Azure AI Foundry provides access to two versions: Sora 1: The original model focused primarily on text-to-video generation with extensive resolution options (480p to 1080p) and flexible duration (1-20 seconds) Sora 2: The enhanced version with native audio generation, multiple generation modes (text-to-video, image-to-video, video-to-video remix), but more constrained resolution options (720p only in public preview) Azure AI Foundry vs. OpenAI API Structure Key Architectural Differences Sora 1 uses Azure's traditional deployment-based API structure: Endpoint Pattern: https://{resource-name}.openai.azure.com/openai/deployments/{deployment-name}/... Parameters: Uses Azure-specific naming like n_seconds, n_variants, separate width/height fields Job Management: Uses /jobs/{id} for status polling Content Download: Uses /video/generations/{generation_id}/content/video Sora 2 adapts OpenAI's v1 API format while still being hosted on Azure: Endpoint Pattern: https://{resource-name}.openai.azure.com/openai/deployments/{deployment-name}/videos Parameters: Uses OpenAI-style naming like seconds (string), size (combined dimension string like "1280x720") Job Management: Uses /videos/{video_id} for status polling Content Download: Uses /videos/{video_id}/content Why This Matters? This architectural difference requires conditional request formatting in your code: const isSora2 = deployment.toLowerCase().includes('sora-2'); if (isSora2) { requestBody = { model: deployment, prompt, size: `${width}x${height}`, // Combined format seconds: duration.toString(), // String type }; } else { requestBody = { model: deployment, prompt, height, // Separate dimensions width, n_seconds: duration.toString(), // Azure naming n_variants: variants, }; } API Integration: Request Body Parameters Sora 1 API Parameters Standard Text-to-Video Request: { "model": "sora-1", "prompt": "Wide shot of a child flying a red kite in a grassy park, golden hour sunlight, camera slowly pans upward.", "height": "720", "width": "1280", "n_seconds": "12", "n_variants": "2" } Parameter Details: model (String, Required): Your Azure deployment name prompt (String, Required): Natural language description of the video (max 32000 chars) height (String, Required): Video height in pixels width (String, Required): Video width in pixels n_seconds (String, Required): Duration (1-20 seconds) n_variants (String, Optional): Number of variations to generate (1-4, constrained by resolution) Sora 2 API Parameters Text-to-Video Request: { "model": "sora-2", "prompt": "A serene mountain landscape with cascading waterfalls, cinematic drone shot", "size": "1280x720", "seconds": "12" } Image-to-Video Request (uses FormData): const formData = new FormData(); formData.append('model', 'sora-2'); formData.append('prompt', 'Animate this image with gentle wind movement'); formData.append('size', '1280x720'); formData.append('seconds', '8'); formData.append('input_reference', imageFile); // JPEG/PNG/WebP Video-to-Video Remix Request: Endpoint: POST .../videos/{video_id}/remix Body: Only { "prompt": "your new description" } The original video's structure, motion, and framing are reused while applying the new prompt Parameter Details: model (String, Optional): Your deployment name prompt (String, Required): Video description size (String, Optional): Either "720x1280" or "1280x720" (defaults to "720x1280") seconds (String, Optional): "4", "8", or "12" (defaults to "4") input_reference (File, Optional): Reference image for image-to-video mode remix_video_id (String, URL parameter): ID of video to remix Video Generation Modes 1. Text-to-Video (Both Models) The foundational mode where you provide a text prompt describing the desired video. Implementation: const response = await fetch(endpoint, { method: 'POST', headers: { 'Content-Type': 'application/json', 'api-key': apiKey, }, body: JSON.stringify({ model: deployment, prompt: "A train journey through mountains with dramatic lighting", size: "1280x720", seconds: "12", }), }); Best Practices: Include shot type (wide, close-up, aerial) Describe subject, action, and environment Specify lighting conditions (golden hour, dramatic, soft) Add camera movement if desired (pans, tilts, tracking shots) 2. Image-to-Video (Sora 2 Only) Generate a video anchored to or starting from a reference image. Key Requirements: Supported formats: JPEG, PNG, WebP Image dimensions must exactly match the selected video resolution Our implementation automatically resizes uploaded images to match Implementation Detail: // Resize image to match video dimensions const targetWidth = parseInt(width); const targetHeight = parseInt(height); const resizedImage = await resizeImage(inputReference, targetWidth, targetHeight); // Send as multipart/form-data formData.append('input_reference', resizedImage); 3. Video-to-Video Remix (Sora 2 Only) Create variations of existing videos while preserving their structure and motion. Use Cases: Change weather conditions in the same scene Modify time of day while keeping camera movement Swap subjects while maintaining composition Adjust artistic style or color grading Endpoint Structure: POST {base_url}/videos/{original_video_id}/remix?api-version=2024-08-01-preview Implementation: let requestEndpoint = endpoint; if (isSora2 && remixVideoId) { const [baseUrl, queryParams] = endpoint.split('?'); const root = baseUrl.replace(/\/videos$/, ''); requestEndpoint = `${root}/videos/${remixVideoId}/remix${queryParams ? '?' + queryParams : ''}`; } Cost Analysis per Generation Sora 1 Pricing Model Base Rate: ~$0.05 per second per variant at 720p Resolution Scaling: Cost scales linearly with pixel count Formula: const basePrice = 0.05; const basePixels = 1280 * 720; // Reference resolution const currentPixels = width * height; const resolutionMultiplier = currentPixels / basePixels; const totalCost = basePrice * duration * variants * resolutionMultiplier; Examples: 720p (1280×720), 12 seconds, 1 variant: $0.60 1080p (1920×1080), 12 seconds, 1 variant: $1.35 720p, 12 seconds, 2 variants: $1.20 Sora 2 Pricing Model Flat Rate: $0.10 per second per variant (no resolution scaling in public preview) Formula: const totalCost = 0.10 * duration * variants; Examples: 720p (1280×720), 4 seconds: $0.40 720p (1280×720), 12 seconds: $1.20 720p (720×1280), 8 seconds: $0.80 Note: Since Sora 2 currently only supports 720p in public preview, resolution doesn't affect cost, only duration matters. Cost Comparison Scenario Sora 1 (720p) Sora 2 (720p) Winner 4s video $0.20 $0.40 Sora 1 12s video $0.60 $1.20 Sora 1 12s + audio N/A (no audio) $1.20 Sora 2 (unique) Image-to-video N/A $0.40-$1.20 Sora 2 (unique) Recommendation: Use Sora 1 for cost-effective silent videos at various resolutions. Use Sora 2 when you need audio, image/video inputs, or remix capabilities. Technical Limitations & Constraints Sora 1 Limitations Resolution Options: 9 supported resolutions from 480×480 to 1920×1080 Includes square, portrait, and landscape formats Full list: 480×480, 480×854, 854×480, 720×720, 720×1280, 1280×720, 1080×1080, 1080×1920, 1920×1080 Duration: Flexible: 1 to 20 seconds Any integer value within range Variants: Depends on resolution: 1080p: Variants disabled (n_variants must be 1) 720p: Max 2 variants Other resolutions: Max 4 variants Concurrent Jobs: Maximum 2 jobs running simultaneously Job Expiration: Videos expire 24 hours after generation Audio: No audio generation (silent videos only) Sora 2 Limitations Resolution Options (Public Preview): Only 2 options: 720×1280 (portrait) or 1280×720 (landscape) No square formats No 1080p support in current preview Duration: Fixed options only: 4, 8, or 12 seconds No custom durations Defaults to 4 seconds if not specified Variants: Not prominently supported in current API documentation Focus is on single high-quality generations with audio Concurrent Jobs: Maximum 2 jobs (same as Sora 1) Job Expiration: 24 hours (same as Sora 1) Audio: Native audio generation included (dialogue, sound effects, ambience) Shared Constraints Concurrent Processing: Both models enforce a limit of 2 concurrent video jobs per Azure resource. You must wait for one job to complete before starting a third. Job Lifecycle: queued → preprocessing → processing/running → completed Download Window: Videos are available for 24 hours after completion. After expiration, you must regenerate the video. Generation Time: Typical: 1-5 minutes depending on resolution, duration, and API load Can occasionally take longer during high demand Resolution & Duration Support Matrix Sora 1 Support Matrix Resolution Aspect Ratio Max Variants Duration Range Use Case 480×480 Square 4 1-20s Social thumbnails 480×854 Portrait 4 1-20s Mobile stories 854×480 Landscape 4 1-20s Quick previews 720×720 Square 4 1-20s Instagram posts 720×1280 Portrait 2 1-20s TikTok/Reels 1280×720 Landscape 2 1-20s YouTube shorts 1080×1080 Square 1 1-20s Premium social 1080×1920 Portrait 1 1-20s Premium vertical 1920×1080 Landscape 1 1-20s Full HD content Sora 2 Support Matrix Resolution Aspect Ratio Duration Options Audio Generation Modes 720×1280 Portrait 4s, 8s, 12s ✅ Yes Text, Image, Video Remix 1280×720 Landscape 4s, 8s, 12s ✅ Yes Text, Image, Video Remix Note: Sora 2's limited resolution options in public preview are expected to expand in future releases. Implementation Best Practices 1. Job Status Polling Strategy Implement adaptive backoff to avoid overwhelming the API: const maxAttempts = 180; // 15 minutes max let attempts = 0; const baseDelayMs = 3000; // Start with 3 seconds while (attempts < maxAttempts) { const response = await fetch(statusUrl, { headers: { 'api-key': apiKey }, }); if (response.status === 404) { // Job not ready yet, wait longer const delayMs = Math.min(15000, baseDelayMs + attempts * 1000); await new Promise(r => setTimeout(r, delayMs)); attempts++; continue; } const job = await response.json(); // Check completion (different status values for Sora 1 vs 2) const isCompleted = isSora2 ? job.status === 'completed' : job.status === 'succeeded'; if (isCompleted) break; // Adaptive backoff const delayMs = Math.min(15000, baseDelayMs + attempts * 1000); await new Promise(r => setTimeout(r, delayMs)); attempts++; } 2. Handling Different Response Structures Sora 1 Video Download: const generations = Array.isArray(job.generations) ? job.generations : []; const genId = generations[0]?.id; const videoUrl = `${root}/${genId}/content/video`; Sora 2 Video Download: const videoUrl = `${root}/videos/${jobId}/content`; 3. Error Handling try { const response = await fetch(endpoint, fetchOptions); if (!response.ok) { const error = await response.text(); throw new Error(`Video generation failed: ${error}`); } // ... handle successful response } catch (error) { console.error('[VideoGen] Error:', error); // Implement retry logic or user notification } 4. Image Preprocessing for Image-to-Video Always resize images to match the target video resolution: async function resizeImage(file: File, targetWidth: number, targetHeight: number): Promise<File> { return new Promise((resolve, reject) => { const img = new Image(); const canvas = document.createElement('canvas'); const ctx = canvas.getContext('2d'); img.onload = () => { canvas.width = targetWidth; canvas.height = targetHeight; ctx.drawImage(img, 0, 0, targetWidth, targetHeight); canvas.toBlob((blob) => { if (blob) { const resizedFile = new File([blob], file.name, { type: file.type }); resolve(resizedFile); } else { reject(new Error('Failed to create resized image blob')); } }, file.type); }; img.onerror = () => reject(new Error('Failed to load image')); img.src = URL.createObjectURL(file); }); } 5. Cost Tracking Implement cost estimation before generation and tracking after: // Pre-generation estimate const estimatedCost = calculateCost(width, height, duration, variants, soraVersion); // Save generation record await saveGenerationRecord({ prompt, soraModel: soraVersion, duration: parseInt(duration), resolution: `${width}x${height}`, variants: parseInt(variants), generationMode: mode, estimatedCost, status: 'queued', jobId: job.id, }); // Update after completion await updateGenerationStatus(jobId, 'completed', { videoId: finalVideoId }); 6. Progressive User Feedback Provide detailed status updates during the generation process: const statusMessages: Record<string, string> = { 'preprocessing': 'Preprocessing your request...', 'running': 'Generating video...', 'processing': 'Processing video...', 'queued': 'Job queued...', 'in_progress': 'Generating video...', }; onProgress?.(statusMessages[job.status] || `Status: ${job.status}`); Conclusion Building with Azure OpenAI's Sora models requires understanding the nuanced differences between Sora 1 and Sora 2, both in API structure and capabilities. Key takeaways: Choose the right model: Sora 1 for resolution flexibility and cost-effectiveness; Sora 2 for audio, image inputs, and remix capabilities Handle API differences: Implement conditional logic for parameter formatting and status polling based on model version Respect limitations: Plan around concurrent job limits, resolution constraints, and 24-hour expiration windows Optimize costs: Calculate estimates upfront and track actual usage for better budget management Provide great UX: Implement adaptive polling, progressive status updates, and clear error messages The future of AI video generation is exciting, and Azure AI Foundry provides production-ready access to these powerful models. As Sora 2 matures and limitations are lifted (especially resolution options), we'll see even more creative applications emerge.

Building an AI Red Teaming Framework: A Developer's Guide to Securing AI Applications
As an AI developer working with Microsoft Foundry, and custom chatbot deployments, I needed a way to systematically test AI applications for security vulnerabilities. Manual testing wasn't scalable, and existing tools didn't fit my workflow. So I built a configuration-driven AI Red Teaming framework from scratch. This post walks through how I architected and implemented a production-grade framework that: Tests AI applications across 8 attack categories (jailbreak, prompt injection, data exfiltration, etc.) Works with Microsoft Foundry, OpenAI, and any REST API Executes 45+ attacks in under 5 minutes Generates multi-format reports (JSON/CSV/HTML) Integrates into CI/CD pipelines What You'll Learn: Architecture patterns (Dependency Injection, Strategy Pattern, Factory Pattern) How to configure 21 attack strategies using JSON Building async attack execution engines Integrating with Microsoft Foundry endpoints Automating security testing in DevOps workflows This isn't theory—I'll show you actual code, configurations, and results from the framework I built for testing AI applications in production. The observations in this post are based on controlled experimentation in a specific testing environment and should be interpreted in that context. Why I Built This Framework As an AI developer, I faced a critical challenge: how do you test AI applications for security vulnerabilities at scale? The Manual Testing Problem: 🐌 Testing 8 attack categories manually took 4+ hours 🔄 Same prompt produces different outputs (probabilistic behavior) 📉 No structured logs or severity classification ⚠️ Can't test on every model update or prompt change 🧠 Semantic failures emerge from context, not just code logic Real Example from Early Testing: Prompt Injection Test (10 identical runs): - Successful bypass: 3/10 (30%) - Partial bypass: 2/10 (20%) - Complete refusal: 5/10 (50%) 💡 Key Insight: Traditional "pass/fail" testing doesn't work for AI. You need probabilistic, multi-iteration approaches. What I Needed: A framework that could: Execute attacks systematically across multiple categories Work with Microsoft Foundry, OpenAI, and custom REST endpoints Classify severity automatically (Critical/High/Medium/Low) Generate reports for both developers and security teams Run in CI/CD pipelines on every deployment So I built it. Architecture Principles Before diving into code, I established core design principles: These principles guided every implementation decision.

Final Thoughts Can red teaming be relied upon as a rigorous and repeatable testing strategy? Yes, with important caveats. Red teaming is reliable for discovering risk patterns, enabling continuous evaluation at scale, and providing decision-support data. But it cannot provide absolute guarantees (85% consistency, not 100%), replace human judgment, or cover every attack vector. The key: Treat red teaming as an engineering discipline—structured, measured, automated, and interpreted statistically.

This three-part series explores how these technologies connect to help enterprises build AI agents that are secure, governed, and deeply integrated with Microsoft’s product ecosystem. Series Overview Part 1: Publishing from Foundry to Microsoft 365 Copilot and Microsoft Teams Part 2: Foundry + Agent 365 — Native Integration for Enterprise AI Part 3: Microsoft Copilot Studio Integration with Foundry Agents This blog focuses on Part 1: Publishing from Foundry to Microsoft 365 Copilot—how developers can now publish agents built in Foundry directly to Microsoft 365 Copilot and Teams in just a few clicks. Build once. Publish everywhere. Developers can now take an AI agent built in Microsoft Foundry and publish it directly to Microsoft 365 Copilot and Microsoft Teams in just a few clicks. The new streamlined publishing flow eliminates manual setup across Entra ID, Azure Bot Service, and manifest files, turning hours of configuration into a seamless, guided flow in the Foundry Playground. Simplifying Agent Publishing for Microsoft 365 Copilot & Microsoft Teams Previously, deploying a Foundry AI agent into Microsoft 365 Copilot and Microsoft Teams required multiple steps: app registration, bot provisioning, manifest editing, and admin approval. With the new Foundry → M365 integration, the process is straightforward and intuitive. Key capabilities No-code publishing — Prepare, package, and publish agents directly from Foundry Playground. Unified build — A single agent package powers multiple Microsoft 365 channels, including Teams Chat, Microsoft 365 Copilot Chat, and BizChat. Agent-type agnostic — Works seamlessly whether you have a prompt agent, hosted agent, or workflow agent. Built-in Governance — Every agent published to your organization is automatically routed through Microsoft 365 Admin Center (MAC) for review, approval, and monitoring. Downloadable package — Developers can download a .zip for local testing or submission to the Microsoft Marketplace. For pro-code developers, the experience is also simplified. A C# code-first sample in the Agent Toolkit for Visual Studio is searchable, featured, and ready to use. Why It Matters This integration isn’t just about convenience; it’s about scale, control, and trust. Faster time to value — Deliver intelligent agents where people already work, without infrastructure overhead. Enterprise control — Admins retain full oversight via Microsoft 365 Admin Center, with built-in approval, review and governance flows. Developer flexibility — Both low-code creators and pro-code developers benefit from the unified publishing experience. Better Together — This capability lays the groundwork for Agent 365 publishing and deeper M365 integrations. Real-world scenarios YoungWilliams built Priya, an AI agent that helps handle government service inquiries faster and more efficiently. Using the one-click publishing flow, Priya was quickly deployed to Microsoft Teams and M365 Copilot without manual setup. This allowed Young Williams’ customers to provide faster, more accurate responses while keeping governance and compliance intact. “Integrating Microsoft Foundry with Microsoft 365 Copilot fundamentally changed how we deliver AI solutions to our government partners,” said John Tidwell, CTO of YoungWilliams. “With Foundry’s one-click publishing to Teams and Copilot, we can take an idea from prototype to production in days instead of weeks—while maintaining the enterprise-grade security and governance our clients expect. It’s a game changer for how public services can adopt AI responsibly and at scale.” Availability Publishing from Foundry to M365 is in Public Preview within the Foundry Playground. Developers can explore the preview in Microsoft Foundry and test the Teams / M365 publishing flow today. SDK and CLI extensions for code-first publishing are generally available.

Fine‑tuning isn’t just “better prompts.” It’s how you tailor a foundation model to your domain and tasks to get higher accuracy, lower cost, and faster responses -- then run it at scale. As Agents become more critical to businesses, we’re seeing growing demand for fine tuning to ensure agents are low latency, low cost, and call the right tools and the right time. At Ignite 2025, we saw how Docusign fine-tuned models that powered their document management system to achieve major gains: more than 50% cost reduction per document, 2x faster inference time, and significant improvements in accuracy. At Ignite, we launched several new features in Microsoft Foundry that make fine‑tuning easier, more scalable, and more impactful than ever with the goal of making agents unstoppable in the real world: New Open-Source models – Qwen3 32B, Ministral 3B, GPT-OSS-20B and Llama 3.3 70B – to give users access to Open-Source models in the same low friction experience as OpenAI Synthetic data generation to jump start your training journey – just upload your documents and our multi-agent system takes care of the rest Developer Training tier to reduce the barrier to entry by offering discounted training (50% off global!) on spot capacity Agentic Reinforcement Fine-tuning with GPT-5: leverage tool calling during chain of thought to teach reasoning models to use your tools to solve complex problems And if that wasn’t enough, we also released a re-imagined fine tuning experience in Foundry (new), providing access to all these capabilities in a simplified and unified UI. New Open-Source Models for Fine-tuning (Public Preview): Bringing open-source innovation to your fingertips We’ve expanded our model lineup to new open-source models you can fine-tune without worrying about GPUs or compute. Ministral-3B and Qwen3 32B are now available to fine-tune with Supervised Fine-Tuning (SFT) in Microsoft Foundry, enabling developers to adapt open-source models to their enterprise-specific domains with ease. Look out for Llama 3.3 70B and GPT-OSS-20B, coming next week! These OSS models are offered through a unified interface with OpenAI via the UI or Foundry SDK which means the same experience, regardless of model choice. These models can be used alongside your favorite Foundry tools, from AI Search to Evaluations, or to power your agents. Note: New OSS models are only available in "New" Foundry – so upgrade today! Like our OpenAI models, Open-Source models in Foundry charge per-token for training, making it simple to forecast and estimate your costs. All models are available on Global Standard tier, making discoverability easy. For more details on pricing, please see our Microsoft Foundry Models pricing page. Customers like Co-Star Group have already seen success leveraging fine tuning with Mistral models to power their home search experience on Homes.com. They selected Ministral-3B as a small, efficient model to power high volume, low latency processing with lower costs and faster deployment times than Frontier models – while still meeting their needs for accuracy, scalability, and availability thanks to fine tuning in Foundry. Synthetic data generation (Public Preview): Create high-quality training data automatically Developers can now generate high-quality, domain-specific synthetic datasets to close those persistent data gaps with synthetic data generation. One of the biggest challenges we hear teams face during fine-tuning is not having enough data or the right kind of data because it’s scarce, sensitive, or locked behind compliance constraints (think healthcare and finance). Our new synthetic data generation capability solves this by giving you a safe, scalable way to create realistic, diverse datasets tailored to your use case so you can fine-tune and evaluate models without waiting for perfect real-world data. Now, you can produce realistic question–answer pairs from your documents, or simulate multi‑turn tool‑use dialogues that include function calls without touching sensitive production data. How it works: Fine‑tuning datasets: Upload a reference file (PDF/Markdown/TXT) and Foundry converts it into SFT‑formatted Q&A pairs that reflect your domain’s language and nuances so your model learns from the right examples. Agent tool‑use datasets: Provide an OpenAPI (Swagger) spec, and Foundry simulates multi‑turn assistant–user conversations with tool calls, producing SFT‑ready examples that teach models to call your APIs reliably. Evaluation datasets: Generate distinct test queries tailored to your scenarios so you can measure model and agent quality objectively—separate from your training data to avoid false confidence. Agents succeed when they reliably understand domain intent and call the right tools at the right time. Foundry’s synthetic data generation does exactly that: it creates task‑specific training and test data so your agent learns from the right examples and you can prove it works before you go live so they are reliable in the real world. Developer Training Tier (Public Preview): 50% discount on training jobs Fine-tuning can be expensive, especially when you may need to run multiple experiments to create the right model for your production agents. To make it easier than ever to get started, we’re introducing Developer Training tier – providing users with a 50% discount when they choose to run workloads on pre-emptible capacity. It also lets users iterate faster: we support up to 10 concurrent jobs on Developer tier, making it ideal for running experiments in parallel. Because it uses reclaimable capacity, jobs may be pre‑empted and automatically resumed, so they may take longer to complete. When to use Developer Training tier: When cost matters - great for early experimentation or hyperparameter tuning thanks to 50% lower training cost. When you need high concurrency - supports up to 10 simultaneous jobs, ideal for running multiple experiments in parallel. When the workload is non‑urgent - suitable for jobs that can tolerate pre-emption and longer, capacity-dependent runtimes. Agentic Reinforcement Fine‑Tuning (RFT) (Private Preview): Train reasoning models to use your tools through outcome based optimization Building reliable AI agents requires more than copying correct behavior; models need to learn which reasoning paths lead to successful outcomes. While supervised fine-tuning trains models to imitate demonstrations, reinforcement fine-tuning optimizes models based on whether their chain of thought actually generates a successful outcome. It teaches them to think in new ways, about new domains – to solve complex problems. Agentic RFT applies this to tool-using workflows: the model generates multiple reasoning traces (including tool calls and planning steps), receives feedback on which attempts solved the problem correctly, and updates its reasoning patterns accordingly. This helps models learn effective strategies for tool sequencing, error recovery, and multi-step planning—behaviors that are difficult to capture through demonstrations alone. The difference now is that you can provide your own custom tools for use during chain of thought: models can interact with your own internal systems, retrieve the data they need, and access your proprietary APIs to solve your unique problems. Agentic RFT is currently available in private preview for o4-mini and GPT-5, with configurable reasoning effort, sampling rates, and per-run telemetry. Request access at aka.ms/agentic-rft-preview. What are customers saying? Fine-tuning is critical to achieve the accuracy and latency needed for enterprise agentic workloads. Decagon is used by many of the world’s most respected enterprises to build, manage and scale AI agents that can resolve millions of customer inquiries across chat, email, and voice – 24 hours a day, seven days a week. This experience is powered by fine-tuning: “Providing accurate responses with minimal latency is fundamental to Decagon’s product experience. We saw an opportunity to reduce latency while improving task-specific accuracy by fine-tuning models using our proprietary datasets. Via fine-tuning, we were able to exceed the performance of larger state of the art models with smaller, lighter-weight models which could be served significantly faster.” -- Cyrus Asgari, Lead Research Engineer for fine-tuning at Decagon But it’s not just agent-first startups seeing results. Companies like Discover Bank are using fine tuned models to provide better customer experiences with personal banking agents: We consolidated three steps into one, response times that were previously five or six seconds came down to one and a half to two seconds on average. This approach made the system more efficient and the 50% reduction in latency made conversations with Discovery AI feel seamless. - Stuart Emslie, Head of Actuarial and Data Science at Discovery Bank Fine-tuning has evolved from an optimization technique to essential infrastructure for production AI. Whether building specialized agents or enhancing existing products, the pattern is clear: custom-trained models deliver the accuracy and speed that general-purpose models can't match. As techniques like Agentic RFT and synthetic data generation mature, the question isn't whether to fine-tune, but how to build the systems to do it systematically.

Hybrid AI is quickly becoming one of the most practical architectures for real-world applications—especially when privacy, compliance, or sensitive data handling matter. Today, it’s increasingly common for users to have capable GPUs in their laptops or desktops, and the ecosystem of small, efficient open-source language models has grown dramatically. That makes local inference not only possible, but easy. In this guide, we explore how a locally run agent built with the Agent Framework can combine the strengths of cloud models in Azure AI Foundry with a local LLM running on your own GPU through Foundry Local. This pattern allows you to use powerful cloud reasoning without ever sending raw sensitive data—like medical labs, legal documents, or financial statements—off the device. Part 1 focuses on the foundations of this architecture, using a simple illustrative example to show how local and cloud inference can work together seamlessly under a single agent. Disclaimer: The diagnostic results, symptom checker, and any medical guidance provided in this article are for illustrative and informational purposes only. They are not intended to provide medical advice, diagnosis, or treatment. Demonstrating the concept Problem Statement We’ve all done it: something feels off, we get a strange symptom, or a lab report pops into our inbox—and before thinking twice, we copy-paste way too much personal information into whatever website or chatbot seems helpful at the moment. Names, dates of birth, addresses, lab values, clinic details… all shared out of habit, usually because we just want answers quickly. This guide uses a simple, illustrative scenario—a symptom checker with lab report summarization—to show how hybrid AI can help reduce that oversharing. It’s not a medical product or a clinical solution, but it’s a great way to understand the pattern. With Microsoft Foundry, Foundry Local, and the Agent Framework, we can build workflows where sensitive data stays on the user’s machine and is processed locally, while the cloud handles the heavier reasoning. Only a safe, structured summary ever leaves the device. The Agent Framework handles when to use the local model vs. the cloud model, giving us a seamless and privacy-preserving hybrid experience. Demo scenario This demo uses a simple, illustrative symptom-checker to show how hybrid AI keeps sensitive data private while still benefiting from powerful cloud reasoning. It’s not a medical product—just an easy way to demonstrate the pattern: Here’s what happens: A Python agent (Agent Framework) runs locally and can call both cloud models and local tools. Azure AI Foundry (GPT-4o) handles reasoning and triage logic but never sees raw PHI. Foundry Local runs a small LLM (phi-4-mini) on your GPU and processes the raw lab report entirely on-device. A tool function (@ai_function) lets the agent call the local model automatically when it detects lab-like text. The flow is simple: user_message = symptoms + raw lab text agent → calls local tool → local LLM returns JSON cloud LLM → uses JSON to produce guidance Environment setup Foundry Local Service On the local machine with GPU, let's install Foundry local using: PS C: \Windows\system32> winget install Microsoft.FoundryLocal Then let's download our local model, in this case phi-4-mini and test it: PS C:\Windows\system32> foundry model download phi-4-mini Downloading Phi-4-mini-instruct-cuda-gpu:5...

Foundry Local models don’t always use simple names like "phi-4-mini". Each installed model has a specific Model ID that Foundry Local assigns (for example: Phi-4-mini-instruct-cuda-gpu:5 in this case). We now can use the Model ID for a quick test: from openai import OpenAI client = OpenAI(base_url="http://127.0.0.1:52403/v1", api_key="ignored") resp = client.chat.completions.create( model="Phi-4-mini-instruct-cuda-gpu:5", messages=[{"role": "user", "content": "Say hello"}]) Returned 200 OK. Microsoft Foundry To handle the cloud part of the hybrid workflow, we start by creating a Microsoft AI Foundry project. This gives us an easy, managed way to use models like GPT-4o-mini —no deployment steps, no servers to configure. You simply point the Agent Framework at your project, authenticate, and you’re ready to call the model. A nice benefit is that Microsoft Foundry and Foundry Local share the same style of API. Whether you call a model in the cloud or on your own machine, the request looks almost identical. This consistency makes hybrid development much easier: the agent doesn’t need different logic for local vs. cloud models—it just switches between them when needed. Under the Hood of Our Hybrid AI Workflow Agent Framework For the agent code, I am using the Agent Framework libraries, and I am giving specific instructions to the agent as per below: from agent_framework import ChatAgent, ai_function from agent_framework.azure import AzureAIAgentClient from azure.identity.aio import AzureCliCredential # ========= Cloud Symptom Checker Instructions ========= SYMPTOM_CHECKER_INSTRUCTIONS = """ You are a careful symptom-checker assistant for non-emergency triage. General behavior: - You are NOT a clinician. Do NOT provide medical diagnosis or prescribe treatment. - First, check for red-flag symptoms (e.g., chest pain, trouble breathing, severe bleeding, stroke signs, one-sided weakness, confusion, fainting). If any are present, advise urgent/emergency care and STOP. - If no red-flags, summarize key factors (age group, duration, severity), then provide: 1) sensible next steps a layperson could take, 2) clear guidance on when to contact a clinician, 3) simple self-care advice if appropriate. - Use plain language, under 8 bullets total. - Always end with: "This is not medical advice." Tool usage: - When the user provides raw lab report text, or mentions “labs below” or “see labs”, you MUST call the `summarize_lab_report` tool to convert the labs into structured data before giving your triage guidance. - Use the tool result as context, but do NOT expose the raw JSON directly. Instead, summarize the key abnormal findings in plain language. """.strip() Referencing the local model Now I am providing a system prompt for the locally inferred model to transform the lab result text into a JSON object with lab results only: # ========= Local Lab Summarizer (Foundry Local + Phi-4-mini) ========= FOUNDRY_LOCAL_BASE = "http://127.0.0.1:52403" # from `foundry service status` FOUNDRY_LOCAL_CHAT_URL = FOUNDRY_LOCAL_BASE + "/v1/chat/completions" # This is the model id you confirmed works: FOUNDRY_LOCAL_MODEL_ID = "Phi-4-mini-instruct-cuda-gpu:5" LOCAL_LAB_SYSTEM_PROMPT = """ You are a medical lab report summarizer running locally on the user's machine. You MUST respond with ONLY one valid JSON object. Do not include any explanation, backticks, markdown, or text outside the JSON.

Do NOT invent values. """.strip() Agent Framework tool In this next step, we wrap the local Foundry inference inside an Agent Framework tool using the AI_function decorator. This abstraction is more than styler—it is the recommended best practice for hybrid architectures. By exposing local GPU inference as a tool, the cloud-hosted agent can decide when to call it, pass structured arguments, and consume the returned JSON seamlessly. It also ensures that the raw lab text (which may contain PII) stays strictly within the local function boundary, never entering the cloud conversation. Using a tool in this way provides a consistent, declarative interface, enables automatic reasoning and tool-routing by frontier models, and keeps the entire hybrid workflow maintainable, testable, and secure: @ai_function( name="summarize_lab_report", description=( "Summarize a raw lab report into structured abnormalities using a local model " "running on the user's GPU. Use this whenever the user provides lab results as text." ), ) def summarize_lab_report( lab_text: Annotated[str, Field(description="The raw text of the lab report to summarize.")], ) -> Dict[str, Any]: """ Tool: summarize a lab report using Foundry Local (Phi-4-mini) on the user's GPU.

The agent runs locally, receives a message containing both symptoms and a raw lab report, and decides when to call the local tool. The lab report is summarized on your GPU, and only the structured JSON is passed to the cloud model for reasoning.

Then results are formatted, PII omitted and the GPT-40 model can process the symptom along the results What's next In this example, the agent runs locally and pulls in both cloud and local inference. In Part 2, we’ll explore the opposite architecture: a cloud-hosted agent that can safely call back into a local LLM through a secure gateway. This opens the door to more advanced hybrid patterns where tools running on edge devices, desktops, or on-prem systems can participate in cloud-driven workflows without exposing sensitive data.
