Bringing GigaTIME to Microsoft Foundry: Unlocking Tumor Microenvironment Insights with Multimodal AI
Expanding Microsoft Foundry for Scientific AI Workloads AI is increasingly being applied to model complex real-world systems, from climate and industrial processes to human biology. In healthcare, one of the biggest challenges is translating routinely available data into deeper biological insight at scale. GigaTIME is now available in Microsoft Foundry, bringing advanced multimodal capabilities to healthcare and life sciences. This brings advanced multimodal capabilities into Foundry, with Foundry Labs enabling early exploration and the Foundry platform supporting scalable deployment aligned to the model’s intended use. Read on to understand how GigaTIME works and how you can start exploring it in Foundry. From Routine Slides to Deep Biological Insight Understanding how tumors interact with the immune system is central to modern cancer research. While techniques like multiplex immunofluorescence provide these insights, they are expensive and difficult to scale across large patient populations. GigaTIME addresses this challenge by translating widely available hematoxylin and eosin pathology slides into spatially resolved protein activation maps. This allows researchers to infer biological signals such as immune activity, tumor growth, and cellular interactions at a much deeper level. Developed in collaboration with Providence and the University of Washington, GigaTIME enables analysis of tumor microenvironments across diverse cancer types, helping accelerate discovery and improve understanding of disease biology. Use cases for GigaTIME GigaTIME is designed to support research and evaluation workflows across a range of real-world scientific scenarios: Population-Scale Tumor Microenvironment Analysis: Enable large-scale analysis of tumor–immune interactions by generating virtual multiplex immunofluorescence outputs from routine pathology slides. Biomarker Association Discovery: Identify relationships between protein activation patterns and clinical attributes such as mutations, biomarkers, and disease characteristics. Patient Stratification and Cohort Analysis: Segment patient populations across cancer types and subtypes using spatial and combinatorial signals for research and hypothesis generation. Clinical Trial Retrospective Analysis: Apply GigaTIME to H&E archives from completed clinical trials to retrospectively characterize tumor microenvironment features associated with treatment outcomes, enabling new insights from existing trial data without additional tissue processing. Tumor–Immune Interaction Analysis: Assess whether immune cells are infiltrating tumor regions or being excluded by analyzing spatial relationships between tumor and immune signals. Immune System Structure Characterization: Understand how immune cell populations are organized within tissue to evaluate coordination or fragmentation of immune response. Immune Checkpoint Context Interpretation: Examine how immune activity may be locally regulated by analyzing overlap between immune markers and checkpoint signals. Tumor Proliferation Analysis: Identify actively growing tumor regions by combining proliferation signals with tumor localization. Stromal and Vascular Context Understanding: Analyze how tissue architecture, such as vascular density and desmoplastic stroma, shapes immune cell access to tumor regions, helping characterize mechanisms of immune exclusion or infiltration.

Now in Foundry: Cohere Transcribe, Nanbeige 4.1-3B, and Octen Embedding
This week's Model Mondays edition spans three distinct layers of the AI application stack: Cohere's cohere-transcribe, a 2B Automatic Speech Recognition (ASR) model that ranks first on the Open ASR Leaderboard across 14 languages; Nanbeige's Nanbeige4.1-3B, a compact 3B reasoning model that outperforms models ten times its size on coding, math, and deep-search benchmarks; and Octen's Octen-Embedding-0.6B, a lightweight text embedding model that achieves strong retrieval scores across 100+ languages and industry-specific domains. Together, these three models illustrate how developers can build full AI pipelines—from audio ingestion to language reasoning to semantic retrieval—entirely with open-source models deployed through Microsoft Foundry. Each operates in a different modality and fills a distinct architectural role, making this week's selection especially well-suited for teams assembling production-grade systems across speech, text, and search. Models of the week Cohere's cohere-transcribe-03-2026 Model Specs Parameters / size: 2B Primary task: Automatic Speech Recognition (audio-to-text) Why it's interesting Top-ranked on the Open ASR Leaderboard: cohere-transcribe-03-2026 achieves a 5.42% average Word Error Rate (WER) across 8 English benchmark datasets as of March 26, 2026—placing it first among open models. It reaches 1.25% WER on LibriSpeech Clean and 8.15% on AMI (meeting transcription), demonstrating consistent accuracy across both clean speech and real-world, multi-speaker environments. Benchmarks: Open ASR Leaderboard. 14 languages with a dedicated encoder-decoder architecture: The model uses a large Conformer encoder for acoustic representation extraction paired with a lightweight Transformer decoder for token generation, trained from scratch on 14 languages covering European, East Asian (Chinese Mandarin, Japanese, Korean, Vietnamese), and Arabic. Unlike general-purpose models adapted for ASR, this dedicated architecture makes it efficient without sacrificing accuracy. Long-form audio with automatic chunking: Audio longer than 35 seconds is automatically split into overlapping chunks and reassembled into a coherent transcript—no manual preprocessing required. Batched inference, punctuation control, and per-language configuration are all supported through the standard API. Try it Click on the window above, upload an audio file, and watch how quickly the model transcribes it for you. Or click the link to experiment with the Cohere Transcribe Space and record audio directly from your device. Use Case Prompt Pattern Meeting transcription Submit recorded audio with language tag; retrieve timestamped transcript per speaker turn Call center quality review Batch-process customer call recordings, extract transcript, pass to classification model Medical documentation Transcribe clinical encounters; feed transcript into summarization or structured note pipeline Multilingual content indexing Process podcasts or video audio in any of 14 supported languages; store as searchable text Sample prompt for a legal services deployment: You are building a contract negotiation assistant. A client submits a recorded audio of a 45-minute supplier negotiation call. Using the cohere-transcribe-03-2026 endpoint deployed in Microsoft Foundry, transcribe the call with punctuation enabled for the English audio. Once the transcript is available, pass it to a downstream language model with the following instruction: "Identify all pricing commitments, delivery deadlines, and liability clauses mentioned in this negotiation transcript. For each, note the speaker's position (client or supplier) and flag any terms that appear ambiguous or require legal review." Nanbeige's Nanbeige4.1-3B Model Specs Parameters / size: 3B Context length: 131,072 tokens Primary task: Text generation (reasoning, coding, tool use, deep search) Why it's interesting Reasoning performance that exceeds its size class: Nanbeige4.1-3B scores 76.9 on LiveCodeBench-V6, these results suggest that targeted post-training using Supervised Fine-Tuning (SFT) and Reinforcement Learning (RL) on a focused dataset can yield improvements that scale-based approaches cannot replicate at equivalent parameter counts. Read the technical report: https://huggingface.co/papers/2602.13367. Strong preference alignment at the 3B scale: On Arena-Hard-v2, Nanbeige4.1-3B scores 73.2, compared to 56.0 for Qwen3-32B and 60.2 for Qwen3-30B-A3B—both significantly larger models. This indicates that the model's outputs consistently match human preference for response quality and helpfulness, not just accuracy on structured tasks. Deep-search capability previously absent from small general models: On xBench-DeepSearch-2505, Nanbeige4.1-3B scores 75—matching search-specialized small agents. The model can sustain complex agentic tasks involving more than 500 sequential tool invocations, a capability gap that previously required either specialized search agents or significantly larger models. Native tool-use support: The model's chat template and generation pipeline natively support tool call formatting, making it straightforward to connect to external APIs and build multi-step agentic workflows without additional scaffolding. Try it Use Case Prompt Pattern Code review and fix Provide failing test + stack trace; ask model to diagnose root cause and write corrected implementation Competition-style math Submit problem as structured prompt; use temperature 0.6, top-p 0.95 for consistent reasoning steps Agentic task execution Provide tool definitions as JSON + goal; let model plan and execute tool calls sequentially Long-document Q&A Pass full document (up to 131K tokens) with targeted factual questions; extract structured answers Sample prompt for a software engineering deployment: You are automating pull request review for a backend engineering team. Using the Nanbeige4.1-3B endpoint deployed in Microsoft Foundry, provide the model with a unified diff of a proposed code change and the following system instruction: "You are a senior software engineer reviewing a pull request. For each modified function: (1) summarize what the change does, (2) identify any edge cases that are not handled, (3) flag any security or performance regressions relative to the original, and (4) suggest a specific improvement if one is warranted. Format your output as a structured list per function." Octen's Octen-Embedding-0.6B Model Specs Parameters / size: 0.6B Context length: 32,768 tokens Primary task: Text embeddings (semantic search, retrieval, similarity) Why it's interesting Retrieval performance above larger proprietary models at 0.6B: On the RTEB (Retrieval Text Embedding Benchmark) public leaderboard, Octen-Embedding-0.6B achieves a mean task score of 0.7241—above voyage-3.5 (0.7139), Cohere-embed-v4.0 (0.6534), and text-embedding-3-large (0.6110), despite being a fraction of their parameter count. The model is fine-tuned from Qwen3-Embedding-0.6B via Low-Rank Adaptation (LoRA), demonstrating that targeted fine-tuning on retrieval-specific data can close the gap with larger embedding models. Vertical domain coverage across legal, finance, healthcare, and code: Octen-Embedding-0.6B was trained with explicit coverage of domain-specific retrieval scenarios—legal document matching, financial report Q&A, clinical dialogue retrieval, and code search including SQL. This makes it suitable for regulated-industry applications where generic embedding models tend to underperform on specialized terminology. 32,768-token context for long-document retrieval: The extended context window supports encoding entire legal contracts, earnings reports, or clinical case notes as single embeddings—removing the need to chunk long documents and re-aggregate scores at query time, which can introduce ranking errors. 100+ language support with cross-lingual retrieval: The model handles multilingual and cross-lingual retrieval natively, with strong coverage across languages including English, Chinese, and other major languages via its Qwen3-based architecture—practical for global enterprise applications that span multiple languages. Use Case Prompt Pattern Semantic search Encode user query and document corpus; rank documents by cosine similarity to query embedding Legal precedent retrieval Embed case briefs and query with legal question; retrieve most semantically relevant precedents Cross-lingual document search Encode multilingual document set; submit query in any supported language for cross-lingual retrieval Financial Q&A pipeline Embed earnings reports or filings; retrieve relevant passages to ground downstream language model responses Sample prompt for a global enterprise knowledge base deployment: You are building a clinical decision support tool. Using the Octen-Embedding-0.6B endpoint deployed in Microsoft Foundry, embed a corpus of 10,000 clinical case notes at ingestion time and store the resulting 1024-dimensional vectors in a vector database. At query time, encode an incoming patient presentation summary and retrieve the 5 most semantically similar historical cases. Pass the retrieved cases and the current presentation to a language model with the following instruction: "Based on these five similar cases and their documented outcomes, summarize the most common treatment approaches and flag any cases where the outcome differed significantly from the initial prognosis."

From the Field: Why This Integration Works As an experienced AI Cloud Solution Architect working in Greater China Region (GCR), I’ve seen one emerging pattern that delivers quick wins for some of my customers: combining Microsoft Copilot Studio with an existing Azure AI Search index. Teams choose this approach because it delivers two outcomes immediately: business users get grounded, reliable answers, and enterprises avoid re-building pipelines or re-platforming knowledge stores. This guide shows exactly how to connect Copilot Studio to an Azure AI Search index that is already live, so your copilot can answer confidently using your enterprise documents. What We Assume Is Already Ready To stay focused on the integration step, we assume: You have an Azure AI Search service deployed You have an index containing vectorized content (manuals, PDFs, policies, FAQs) Your platform/data team already handled ingestion, embeddings, and indexing In short, your Azure AI Search endpoint and admin key are ready, and the index already contains chunked content with embeddings. Step 1 - Collect Your Azure AI Search Connection Details From the Azure AI Search resource: Endpoint URL Azure AI Search → Overview → Url: https://<your-search-service>.search.windows.net Admin Key Azure AI Search → Keys Use either the primary or secondary key. Governance tip: For production, rotate keys regularly and use managed identities when possible. Step 2 - Add Azure AI Search as Knowledge Inside Copilot Studio Open your Copilot Studio agent Go to the Knowledge tab Select Add knowledge, choose Azure AI Search Provide: Endpoint URL Admin key Create or select the connection Choose your existing index from the dropdown Select Add to agent Step 3 - Test a Grounded Response Open the Test copilot pane and ask a question your indexed content can answer, such as: “What are the different licensing options available for Power Platform?” Verify that: The Activity Map shows Azure AI Search being invoked The answer reflects the correct document in your index Citations or references appear where applicable Conclusion Business value: You can activate grounded, explainable answers in Copilot Studio immediately by reusing your existing Azure AI Search index - no re-platforming, no new pipelines. Team model: Data/Platform teams own ingestion, enrichment, and vectorization. Business teams build and refine the copilot experience in Copilot Studio. Scale and governance: All components stay inside Azure, with enterprise-grade security, RBAC, and operational monitoring, while enabling low‑code agility for makers.

As organizations scale their use of AI agents, one question keeps surfacing: how much is each agent actually costing us? Not at the subscription level. Not at the resource group level. Per agent, per model, per request. This post walks through a solution that answers that question by combining three Azure services Microsoft AI Foundry, Azure API Management (APIM), and Application Insights into an observable, metered AI gateway with granular token-level telemetry including custom dates greater than a month for deeper analysis. The Problem: AI Costs Can be a Black Box Foundry’s built-in monitoring and cost views are ultimately powered by telemetry stored in Application Insights, and the out-of-the-box dashboards don’t always provide the exact per-request/per-caller token breakdown or the custom aggregations/joins teams may want for bespoke dashboards (for example, breaking down tokens by APIM subscription, product, tenant, user, route, or agent step). Using APIM to stamp consistent caller/context metadata (headers/claims), Foundry to generate the agent/model run telemetry, and App Insights as the queryable store to let you correlate gateway, agent run, tool/model calls and then build custom KQL-driven dashboards. With data captured in App Insights and custom KQL queries, questions such as below can be answered: Which agent consumed the most tokens last week? What's the average cost per request for a specific agent? How do prompt tokens vs. completion tokens break down per model? Is one agent disproportionately expensive compared to others? Why This Solution Was Built This solution was built to close the observability gap between "we deployed agents" and "we understand what those agents cost." The goals were straightforward: Per-agent, per-model cost attribution - Know exactly which agent is consuming what, down to the token. Real-time telemetry, not batch reports - Metrics flow into Application Insights within minutes, query via KQL. Zero agent modification - The agents themselves don't need to know about telemetry. The tracking happens at the gateway layer. Extensibility - Any agent hosted in Microsoft Foundry and exposed through APIM can be added with a single function call. How It Works The architecture is intentionally simple three services, one data flow. The notebook serves as a testing and prototyping environment, but the same `call_agent()` and `track_llm_usage()` code can be lifted directly into any production Python application that calls Foundry agents. Azure API Management acts as the AI Gateway. Every request to a Foundry-hosted agent flows through APIM, which handles routing, rate limiting, authentication, and tracing. APIM adds its own trace headers (`Ocp-Apim-Trace-Location`) so you can correlate gateway-level diagnostics with your application telemetry. After the API request is successfully completed, we can extract the necessary data from response headers. The notebook is designed for testing and rapid iteration call an agent, inspect the response, verify that telemetry lands in App Insights. It uses `httpx` to call agents through APIM, authenticating with `DefaultAzureCredential` and an APIM subscription key. After each response, it extracts the `usage` object `input_tokens`, `output_tokens`, `total_tokens` — and calculates an estimated cost based on built-in per-model pricing. Application Insights receives this telemetry via OpenTelemetry. The solution sends data to two tables: customMetrics - Cumulative counters for prompt tokens, completion tokens, total tokens, and cost in USD. These power dashboards and alerts. traces - Structured log entries with `custom_dimensions` containing agent name, model, operation ID, token counts, and cost per request. These power ad-hoc KQL queries. traces - stores your application’s trace/log messages (plus custom properties/measurements) as queryable records in Azure Monitor Logs. Demonstrating Granular Cost and Usage Metrics This is where the solution shines. Once telemetry is flowing, you can answer detailed questions with simple KQL queries. Per-Request Detail Query the `traces` table to see every individual agent call with full token and cost breakdown: traces | where message == "llm.usage" | extend cd = parse_json(replace_string( tostring(customDimensions["custom_dimensions"]), "'", "\"")) | extend agent_name = tostring(cd["agent_name"]), model = tostring(cd["model"]), prompt_tokens = toint(cd["prompt_tokens"]), completion_tokens = toint(cd["completion_tokens"]), total_tokens = toint(cd["total_tokens"]), cost_usd = todouble(cd["cost_usd"]) | project timestamp, agent_name, model, prompt_tokens, completion_tokens, total_tokens, cost_usd | order by timestamp desc This gives you a line-item audit trail every request, every agent, every token. Aggregated Metrics Per Agent Summarize across all requests to see averages and totals grouped by agent and model: traces | where message == "llm.usage" | extend cd = parse_json(replace_string( tostring(customDimensions["custom_dimensions"]), "'", "\"")) | extend agent_name = tostring(cd["agent_name"]), model = tostring(cd["model"]), prompt_tokens = toint(cd["prompt_tokens"]), completion_tokens = toint(cd["completion_tokens"]), total_tokens = toint(cd["total_tokens"]), cost_usd = todouble(cd["cost_usd"]) | summarize calls = count(), avg_prompt = avg(prompt_tokens), avg_completion = avg(completion_tokens), avg_total = avg(total_tokens), avg_cost = avg(cost_usd), total_cost = sum(cost_usd) by agent_name, model | order by total_cost desc Now you can see at a glance: Which agent is the most expensive across all calls Average token consumption per request useful for prompt optimization Prompt-to-completion ratio a high ratio may indicate verbose system prompts that could be trimmed Cost trends by model is GPT-4.1 worth the premium over GPT-4o-mini for a particular agent? The same can be done in code with your custom solution: from datetime import timedelta from azure.identity import DefaultAzureCredential from azure.monitor.query import LogsQueryClient KQL = r""" traces | where message == "llm.usage" | extend cd_raw = tostring(customDimensions["custom_dimensions"]) | extend cd = parse_json(replace_string(cd_raw, "'", "\"")) | extend agent_name = tostring(cd["agent_name"]), model = tostring(cd["model"]), operation_id = tostring(cd["operation_id"]), prompt_tokens = toint(cd["prompt_tokens"]), completion_tokens = toint(cd["completion_tokens"]), total_tokens = toint(cd["total_tokens"]), cost_usd = todouble(cd["cost_usd"]) | project timestamp, agent_name, model, operation_id, prompt_tokens, completion_tokens, total_tokens, cost_usd | order by timestamp desc """ def query_logs(): credential = DefaultAzureCredential() client = LogsQueryClient(credential) resp = client.query_resource( resource_id=APP_INSIGHTS_RESOURCE_ID, # defined in config cell query=KQL, timespan=None, # No time filter — returns all available data (up to 90-day retention) ) if resp.status != "Success": raise RuntimeError(f"Query failed: {resp.status} - {getattr(resp, 'error', None)}") table = resp.tables[0] rows = [dict(zip(table.columns, r)) for r in table.rows] return rows if __name__ == "__main__": rows = query_logs() if not rows: print("No telemetry found. Wait 2-5 min after running the agent cell and try again.") else: print(f"Found {len(rows)} records\n") print(f"{'Timestamp':<28} {'Agent':<16} {'Model':<12} {'Op ID':<12} " f"{'Prompt':>8} {'Completion':>11} {'Total':>8} {'Cost ($)':>10}") print("-" * 110) for r in rows[:20]: ts = str(r.get("timestamp", ""))[:19] print(f"{ts:<28} {r.get('agent_name',''):<16} {r.get('model',''):<12} " f"{r.get('operation_id',''):<12} {r.get('prompt_tokens',0):>8} " f"{r.get('completion_tokens',0):>11} {r.get('total_tokens',0):>8} " f"{r.get('cost_usd',0):>10.6f}") What You Can Build on Top Azure Workbooks - Build interactive dashboards showing cost trends over time, agent comparison charts, and token distribution heatmaps. Alerts - Trigger notifications when a single agent exceeds a cost threshold or when token consumption spikes unexpectedly. Azure Dashboard pinning - Pin KQL query results directly to a shared Azure Dashboard for team visibility. Power BI integration - Export telemetry data for executive-level cost reporting across all AI agents. Extensibility: Add Any Agent in One Line The solution is designed to scale with your agent portfolio. Any agent hosted in Microsoft Foundry and exposed through APIM can be integrated without modifying the telemetry pipeline. Adding a new agent is a single function call: response = call_agent("YourNewAgent", "Your prompt here") Token tracking, cost estimation, and telemetry export happen automatically. No additional configuration, no new infrastructure. From Notebook to Production The notebook is a testing harness, a fast way to validate agent connectivity, inspect raw responses, and confirm that telemetry arrives in App Insights. But the code isn't limited to notebooks. The core functions `call_agent()`, `track_llm_usage()`, and the OpenTelemetry configuration are plain Python. They can be dropped directly into any production application that calls Foundry agents through APIM: FastAPI / Flask web service - Wrap `call_agent()` in an endpoint and get per-request cost tracking out of the box. Azure Functions - Call agents from a serverless function with the same telemetry pipeline. Background workers or batch pipelines - Process multiple agent calls and aggregate cost data across runs. CLI tools or scheduled jobs - Run agent evaluations on a schedule with automatic cost logging. The pattern stays the same regardless of where the code runs: # 1. Configure OpenTelemetry + App Insights (once at startup) configure_azure_monitor(connection_string=APP_INSIGHTS_CONN) # 2. Call any agent through APIM response = call_agent("FinanceAgent", "Summarize Q4 earnings") # 3. Token usage and cost are tracked automatically # → customMetrics and traces tables in App Insights Start with the notebook to prove the pattern works. Then move the same code into your production codebase, the telemetry travels with it. Key Takeaways AI cost observability matters. As agent counts grow, per-agent cost attribution becomes essential for budgeting and optimization. APIM as an AI Gateway gives you routing, rate limiting, and tracing in one place without touching agent code. OpenTelemetry + Application Insights provides a battle-tested telemetry pipeline that scales from a single notebook to production workloads. KQL makes the data actionable. Per-request audits, per-agent summaries, and cost trending are all a query away. The solution is additive, not invasive. Agents don't need modification. The telemetry layer wraps around them. This approach gives developers the abiility to view metrics per user, API Key, Agent, request / tool call, or business dimensions(Cost Center, app, environment). If you're running AI agents in Microsoft Foundry and want to understand what they cost at a granular level this pattern gives you the visibility to make informed decisions about model selection, prompt design, and budget allocation.

From Knowledgeable to Personalized: Why Memory Matters Most AI agents today are knowledgeable — they ground responses in enterprise data sources and rely on short‑term, session‑based memory to maintain conversational coherence. This works well within a single interaction. But once the session ends, the context disappears. The agent starts fresh, unable to recall prior interactions, user preferences, or previously established context. In reality, enterprise users don’t interact with agents exclusively in one‑off sessions. Conversations can span days, weeks, evolving across multiple interactions rather than isolated sessions. Without a way to persist and safely reuse relevant context across interactions, AI agents remain efficient in the short term be being stateful within a session, but lose continuity over time due to their statelessness across sessions. Bridging this gap between short-term efficiency and long‑term adaptation exposes a deeper challenge. Persisting memory across sessions is not just a technical decision; in enterprise environments, it introduces legitimate concerns around privacy, data isolation, governance, and compliance — especially when multiple users interact with the same agent. What seems like an obvious next step quickly becomes a complex architectural problem, requiring organizations to balance the ability for agents to learn and adapt over time with the need to preserve trust, enforce isolation boundaries, and meet enterprise compliance requirements. In this post, I’ll walk through a practical design pattern for user‑scoped persistent memory, including a reference architecture and a deployable sample implementation that demonstrates how to apply this pattern in a real enterprise setting while preserving isolation, governance, and compliance. The Challenge of Persistent Memory in Enterprise AI Agents Extending memory beyond a single session seems like a natural way to make AI agents more adaptive. Retaining relevant context over time — such as preferences, prior decisions, or recurring patterns — would allow an agent to progressively tailor its behavior to each user, moving from simple responsiveness toward genuine adaptation. In enterprise environments, however, persistence introduces a different class of risk. Storing and reusing user context across interactions raises questions of privacy, data isolation, governance, and compliance — particularly when multiple users interact with shared systems. Without clear ownership and isolation boundaries, naïvely persisted memory can lead to cross‑user data leakage, policy violations, or unclear retention guarantees. As a result, many systems default to ephemeral, session‑only memory. This approach prioritizes safety and simplicity — but does so at the cost of long‑term personalization and continuity. The challenge, then, is not whether agents should remember, but how memory can be introduced without violating enterprise trust boundaries. Persistent Memory: Trade‑offs Between Abstraction and Control As AI agents evolve toward more adaptive behavior, several approaches to agent memory are emerging across the ecosystem. Each reflects a different set of trade-offs between abstraction, flexibility, and control — making it useful to briefly acknowledge these patterns before introducing the design presented here. Microsoft Foundry Agent Service includes a built‑in memory capability (currently in Preview) that enables agents to retain context beyond a single interaction. This approach integrates tightly with the Foundry runtime and abstracts much of the underlying memory management, making it well suited for scenarios that align closely with the managed agent lifecycle. Another notable approach combines Mem0 with Azure AI Search, where memory entries are stored and retrieved through vector search. In this model, memory is treated as an embedding‑centric store that emphasizes semantic recall and relevance. Mem0 is intentionally opinionated, defining how memory is structured, summarized, and retrieved to optimize for ease of use and rapid iteration. Both approaches represent meaningful progress. At the same time, some enterprises require an approach where user memory is explicitly owned, scoped, and governed within their existing data architecture — rather than implicitly managed by an agent framework or memory library. These requirements often stem from stricter expectations around data isolation, compliance, and long‑term control. User-Scoped Persistent Memory with Azure Cosmos DB The solution presented in this post provides a practical reference implementation for organizations that require explicit control over how user memory is stored, scoped, and governed. Rather than embedding long‑term memory implicitly within the agent runtime, this design models memory as a first‑class system component built on Azure Cosmos DB. At a high level, the architecture introduces user‑scoped persistent memory: a durable memory layer in which each user’s context is isolated and managed independently. Persistent memory is stored in Azure Cosmos DB containers partitioned by user identity and consists of curated, long‑lived signals — such as preferences, recurring intent, or summarized outcomes from prior interactions — rather than raw conversational transcripts. This keeps memory intentional, auditable, and easy to evolve over time. Short‑term, in‑session conversation state remains managed by Microsoft Foundry on the server side through its built‑in conversation and thread model. By separating ephemeral session context from durable user memory, the system preserves conversational coherence while avoiding uncontrolled accumulation of long‑term state within the agent runtime. This design enables continuity and personalization across sessions while deliberately avoiding the risks associated with shared or global memory models, including cross‑user data leakage, unclear ownership, and unintended reuse of context. Azure Cosmos DB provides enterprises with direct control over memory isolation, data residency, retention policies, and operational characteristics such as consistency, availability, and scale. In this architecture, knowledge grounding and memory serve complementary roles. Knowledge grounding ensures correctness by anchoring responses in trusted enterprise data sources. User‑scoped persistent memory ensures relevance by tailoring interactions to the individual user over time. Together, they enable trustworthy, adaptive AI agents that improve with use — without compromising enterprise boundaries. Architecture Components and Responsibilities Identity and User Scoping Microsoft Entra ID (App Registrations) — provides the frontend a client ID and tenant ID so the Microsoft Authentication Library (MSAL) can authenticate users via browser redirect. The oid (Object ID) claim from the ID token is used as the user identifier throughout the system. Agent Runtime and Orchestration Microsoft Foundry — serves as the unified AI platform for hosting models, managing agents, and maintaining conversation state. Foundry manages in‑session and thread‑level memory on the server side, preserving conversational continuity while keeping ephemeral context separate from long‑term user memory. Backend Agent Service — implements the AI agent using Microsoft Foundry’s agent and conversation APIs. The agent is responsible for reasoning, tool‑calling decisions, and response generation, delegating memory and search operations to external MCP servers. Memory and Knowledge Services MCP‑Memory — MCP server that hosts tools for extracting structured memory signals from conversations, generating embeddings, and persisting user‑scoped memories. Memories are written to and retrieved from Azure Cosmos DB, enforcing strict per‑user isolation. MCP‑Search — MCP server exposing tools for querying enterprise knowledge sources via Azure AI Search. This separation ensures that knowledge grounding and memory retrieval remain distinct concerns. Azure Cosmos DB for NoSQL — provides the durable, serverless document store for user‑scoped persistent memory. Memory containers are partitioned by user ID, enabling isolation, auditable access, configurable retention policies, and predictable scalability. Vector search is used to support semantic recall over stored memory entries. Azure AI Search — supplies hybrid retrieval (keyword and vector) with semantic reranking over the enterprise knowledge index. An integrated vectorizer backed by an embedding model is used for query‑time vectorization. Models text‑embedding‑3‑large — used for generating vector embeddings for both user‑scoped memories and enterprise knowledge search. gpt‑5‑mini — used for lightweight analysis tasks, such as extracting structured memory facts from conversational context. gpt‑5.1 — powers the AI agent, handling multi‑turn conversations, tool invocation, and response synthesis. Application and Hosting Infrastructure Frontend Web Application — a React‑based web UI that handles user authentication and presents a conversational chat interface. Azure Container Apps Environment — provides a shared execution environment for all services, including networking, scaling, and observability. Azure Container Apps — hosts the frontend, backend agent service, and MCP servers as independently scalable containers. Azure Container Registry — stores container images for all application components. Try It Yourself Demonstration of user‑scoped persistent memory across sessions. To make these concepts concrete, I’ve published a working reference implementation that demonstrates the architecture and patterns described above. The complete solution is available in the Agent-Memory GitHub repository. The repository README includes prerequisites, environment setup notes, and configuration details. Start by cloning the repository and moving into the project directory: git clone https://github.com/mardianto-msft/azure-agent-memory.git cd azure-agent-memory Next, sign in to Azure using the Azure CLI: az login Then authenticate the Azure Developer CLI: azd auth login Once authenticated, deploy the solution: azd up After deployment is complete, sign in using the provided demo users and interact with the agent across multiple sessions. Each user’s preferences and prior context are retained independently, the interaction continues seamlessly after signing out and returning later, and user context remains fully isolated with no cross‑identity leakage. The solution also includes a knowledge index initialized with selected Microsoft Outlook Help documentation, which the agent uses for knowledge grounding. This index can be easily replaced or extended with your own publicly accessible URLs to adapt the solution to different domains. Looking Ahead: Personalized Memory as a Foundation for Adaptive Agents As enterprise AI agents evolve, many teams are looking beyond larger models and improved retrieval toward human‑centered personalization at scale — building agents that adapt to individual users while operating within clearly defined trust boundaries. User‑scoped persistent memory enables this shift. By treating memory as a first‑class, user‑owned component, agents can maintain continuity across sessions while preserving isolation, governance, and compliance. Personalization becomes an intentional design choice, aligning with Microsoft’s human‑centered approach to AI, where users retain control over how systems adapt to them. This solution demonstrates how knowledge grounding and personalized memory serve complementary roles. Knowledge grounding ensures correctness by anchoring responses in trusted enterprise data. Personalized memory ensures relevance by tailoring interactions to the individual user. Together, they enable context‑aware, adaptive, and personalized agents — without compromising enterprise trust. Finally, this solution is intentionally presented as a reference design pattern, not a prescriptive architecture. It offers a practical starting point for enterprises designing adaptive, personalized agents, illustrating how user‑scoped memory can be modeled, governed, and integrated as a foundational capability for scalable enterprise AI.Introducing OpenAI’s GPT-image-1.5 in Microsoft Foundry

The Art of Evaluating LLMs in RAG Systems
🔍 1. Why Evaluating LLM Responses is Hard In classical programming, correctness is binary. Input Expected Result 2 + 2 4 ✔ Correct 2 + 2 5 ✘ Wrong Software is deterministic — same input → same output. LLMs are probabilistic. They generate one of many valid word combinations, like forming sentences from multiple possible synonyms and sentence structures. Example: Prompt: "Explain gravity like I'm 10" Possible responses: Response A Response B Gravity is a force that pulls everything to Earth. Gravity bends space-time causing objects to attract. Both are correct. Which is better? Depends on audience. So evaluation needs to look beyond text similarity. We must check: ✔ Is the answer meaningful? ✔ Is it correct? ✔ Is it easy to understand? ✔ Does it follow prompt intent? Testing LLMs is like grading essays — not checking numeric outputs. 🧠 2. Why RAG Evaluation is Even Harder RAG introduces an additional layer — retrieval. The model no longer answers from memory; it must first read context, then summarise it. Evaluation now has multi-dimensions: Evaluation Layer What we must verify Retrieval Did we fetch the right documents? Understanding Did the model interpret context correctly? Grounding Is the answer based on retrieved data? Generation Quality Is final response complete & clear? A simple story makes this intuitive: Teacher asks student to explain Photosynthesis. Student goes to library → selects a book → reads → writes explanation. We must evaluate: Did they pick the right book? → Retrieval Did they understand the topic? → Reasoning Did they copy facts correctly without inventing? → Faithfulness Is written explanation clear enough for another child to learn from? → Answer Quality One failure → total failure. 🧩 3. Two Types of Evaluation 🔹 Intrinsic Evaluation — Quality of the Response Itself Here we judge the answer, ignoring real-world impact. We check: ✔ Grammar & coherence ✔ Completeness of explanation ✔ No hallucination ✔ Logic flow & clarity ✔ Semantic correctness This is similar to checking how well the essay is written. Even if the result did not solve the real problem, the answer could still look good — that’s why intrinsic alone is not enough. 🔹 Extrinsic Evaluation — Did It Achieve the Goal? This measures task success. If a customer support bot writes a beautifully worded paragraph, but the user still doesn’t get their refund — it failed extrinsically. Examples: System Type Extrinsic Goal Banking RAG Bot Did user get correct KYC procedure? Medical RAG Was advice safe & factual? Legal search assistant Did it return the right section of the law? Technical summariser Did summary capture key meaning? Intrinsic = writing quality. Extrinsic = impact quality. A production-grade RAG system must satisfy both. 📏 4. Core RAG Evaluation Metrics (Explained with Very Simple Analogies) Metric Meaning Analogy Relevance Does answer match question? Ask who invented C++? → model talks about Java ❌ Faithfulness No invented facts Book says started 2004, response says 1990 ❌ Groundedness Answer traceable to sources Claims facts that don’t exist in context ❌ Completeness Covers all parts of question User asks Windows vs Linux → only explains Windows Context Recall / Precision Correct docs retrieved & used Student opens wrong chapter Hallucination Rate Degree of made-up info “Taj Mahal is in London” 😱 Semantic Similarity Meaning-level match “Engine died” = “Car stopped running” 💡 Good evaluation doesn’t check exact wording. It checks meaning + truth + usefulness. 🛠 5. Tools for RAG Evaluation 🔹 1. RAGAS — Foundation for RAG Scoring RAGAS evaluates responses based on: ✔ Faithfulness ✔ Relevance ✔ Context recall ✔ Answer similarity Think of RAGAS as a teacher grading with a rubric. It reads both answer + source documents, then scores based on truthfulness & alignment. 🔹 2. LangChain Evaluators LangChain offers multiple evaluation types: Type What it checks String or regex Basic keyword presence Embedding based Meaning similarity, not text match LLM-as-a-Judge AI evaluates AI (deep reasoning) LangChain = testing toolbox RAGAS = grading framework Together they form a complete QA ecosystem. 🔹 3. PyTest + CI for Automated LLM Testing Instead of manually validating outputs, we automate: Feed preset questions to RAG Capture answers Run RAGAS/LangChain scoring Fail test if hallucination > threshold This brings AI closer to software-engineering discipline. RAG systems stop being experiments — they become testable, trackable, production-grade products. 🚀 6. The Future: LLM-as-a-Judge The future of evaluation is simple: LLMs will evaluate other LLMs. One model writes an answer. Another model checks: ✔ Was it truthful? ✔ Was it relevant? ✔ Did it follow context? This enables: Benefit Why it matters Scalable evaluation No humans needed for every query Continuous improvement Model learns from mistakes Real-time scoring Detect errors before user sees them This is like autopilot for AI systems — not only navigating, but self-correcting mid-flight. And that is where enterprise AI is headed. 🎯 Final Summary Evaluating LLM responses is not checking if strings match. It is checking if the machine: ✔ Understood the question ✔ Retrieved relevant knowledge ✔ Avoided hallucination ✔ Provided complete, meaningful reasoning ✔ Grounded answer in real source text RAG evaluation demands multi-layer validation — retrieval, reasoning, grounding, semantics, safety. Frameworks like RAGAS + LangChain evaluators + PyTest pipelines are shaping the discipline of measurable, reliable AI — pushing LLM-powered RAG from cool demo → trustworthy enterprise intelligence.
