A New Chapter for Realtime AI: Reasoning, Translation, and Real-Time Transcription
Voice can be one of the most direct and productive interfaces for AI — enabling customer support agents that may resolve issues without a single keystroke, live multilingual communication that can take on language barriers as conversations happen, and voice assistants capable of reasoning through complex requests in real time. Developers building these experiences need models that can keep pace with increasingly demanding latency, accuracy, and language coverage requirements. Today, OpenAI’s GPT-realtime-translate, GPT‑realtime‑2 and, GPT-realtime-whisper are rolling out into Microsoft Foundry starting today — together representing a significant step forward for the realtime model lineup available to developers on the platform. GPT-realtime-translate and GPT-realtime-whisper GPT-realtime-translate and GPT-realtime-whisper together extend the realtime stack for live multilingual audio workflows. GPT-realtime-translate is built for continuous, real-time translation, producing translated output as speech unfolds without relying on segmented pipeline processing, while GPT-realtime-whisper provides low-latency streaming transcription of the original audio in parallel. Used together, they help developers support scenarios such as live events, cross-language customer experiences, captions, monitoring, and archival workflows that require both translated output and visibility into the source speech. Continuous stream processing: This new model translates live audio without segmenting or buffering allowing for more natural interactions. New translation and transcription capabilities: Translate between languages in real time and observe faster text to speech. Available via the Realtime API GPT-realtime-2 GPT‑realtime‑2 is a generational upgrade to OpenAI's speech-to-speech model, bringing internal reasoning and an expanded context window to real-time voice applications. Where previous speech to speech models responded immediately, GPT‑realtime‑2 can work through a problem before speaking — making it well suited for voice applications that need to handle complex, multi-step queries entirely in the audio layer without routing to a separate text pipeline. Native reasoning capability: The newest realtime model introduces stronger reasoning capabilities. Now the model thinks internally before responding. Adjustable reasoning effort via {reasoning.effort}: Explicitly request the level of reasoning the model uses -- minimal, low, medium, high – to save on cost and latency. Audio in, audio out: No need for an intermediary text step, conversation stays fluid and natural. Available via the Realtime API Use cases These models work independently, but they're designed to complement each other in real-world pipelines: Live multilingual events. GPT-realtime-translate enables real-time translation of live audio, producing translated speech along with a transcript in the target language. GPT‑realtime‑whisper can be used in parallel to capture a transcription of the original speech for captions, monitoring, or archival purposes. Together, they enable multilingual live streaming with both translated experiences and visibility into the source language. Global customer support. Route inbound calls through GPT-realtime-translate to translate conversations in real time and provide a translated transcript for agents. Use GPT‑realtime‑whisper alongside it to capture the original conversation as text for compliance, quality review, or analytics. Then pass the interaction to an agent built with GPT‑realtime‑2 using {reasoning.effort}: high for complex issue resolution, all within a continuous audio pipeline. International voice assistants. Build once and deploy across languages. GPT-realtime-translate enables multilingual interaction and provides translated output with a target-language transcript, while GPT‑realtime‑whisper can optionally capture the original user input as text. GPT‑realtime‑2 manages reasoning and conversational context, supporting more complex voice interactions.

Now in Foundry: IBM Granite 4.1, NVIDIA Nemotron Nano Omni, and Qwen3.6-35B-A3B
This week Microsoft Foundry adds two major model families alongside a reasoning powerhouse that spans the full spectrum from specialized speech and vision to general-purpose coding and long-context analysis. IBM's Granite 4.1 is a famiily of 10: six LLMs across 3B, 8B, and 30B sizes in both full-precision and FP8 variants, plus a safety model, a vision-language model for document extraction, and a multilingual speech recognition model. NVIDIA's Nemotron-3-Nano-Omni-30B-A3B-Reasoning brings multimodal capability—video, audio, image, and text—to a 31B Mamba2-Transformer Hybrid Mixture-of-Experts (MoE) architecture that activates only 3B parameters per forward pass; three variants are available in Foundry (BF16, FP8, and NVFP4), with the FP8 variant featured here. Qwen3.6-35B-A3B is designed for agentic coding among open models, with thinking preservation across conversation turns and a context window extensible to 1 million tokens. Models of the week IBM: granite-4.1-30b Model Specs Parameters / size: 30B (flagship of the Granite 4.1 family) Context length: 131,072 tokens Primary task: Text generation (multilingual instruction following, RAG, tool calling, code, summarization) Why it's interesting The Granite 4.1 release brings 10 models to Microsoft Foundry. The LLM lineup covers granite-4.1-3b-instruct, granite-4.1-8b-instruct, and granite-4.1-30b-instruct with FP8 variants for each, plus granite-guardian-4.1-8b for safety, granite-vision-4.1-4b for document and chart understanding, and granite-speech-4.1-2b for multilingual speech recognition. This is a deployment-ready stack where teams can mix and match model sizes and modalities from a single provider. Strong instruction following and reasoning at the 30B scale: granite-4.1-30b-instruct scores 80.16 on MMLU, 64.09 on MMLU-Pro, 83.74 on Big-Bench Hard (BBH), 77.80 on AGI Eval, 45.76 on GPQA (Graduate-Level Google-Proof Q&A, a graduate-level science reasoning benchmark), and 89.65 average on IFEval (instruction following). These results reflect SFT and reinforcement learning post-training focused specifically on instruction compliance, tool calling accuracy, and long-context retrieval. (View benchmarks here) Enhanced tool calling and 12-language support: Granite 4.1 models are trained for structured function calling and support 12 languages—Arabic, Chinese, Czech, Dutch, English, French, German, Italian, Japanese, Korean, Portuguese, and Spanish—with dialog, extraction, and summarization capabilities. Safety and multimodal coverage within the same family: The inclusion of granite-guardian-4.1-8b (a safety classifier for detecting harmful content and prompt injections), granite-vision-4.1-4b (a Vision Language Model optimized for document extraction from PDFs, charts, and tables), and granite-speech-4.1-2b (a 2B multilingual Automatic Speech Recognition model) means teams can address safety, document parsing, and audio ingestion within the same model family—reducing integration complexity across a full pipeline. Try it Use Case Prompt Pattern Multilingual RAG Submit retrieved document passages in any of 12 supported languages; ask model to synthesize and cite sources Agentic tool calling Provide function definitions + user goal; model plans and executes tool calls in structured format Document extraction (granite-vision-4.1-4b) Submit PDF page image; extract tables, key figures, or form fields as structured JSON Safety classification (granite-guardian-4.1-8b) Pass user input or model output; receive structured risk assessment before serving response Sample prompt for an enterprise document processing deployment: You are building a multilingual document intelligence pipeline for a global financial institution. Using the granite-4.1-30b-instruct endpoint deployed in Microsoft Foundry, submit each incoming policy or regulatory document with the following system instruction: "You are a compliance analysis assistant. Review the document and extract: (1) all regulatory requirements described, (2) the entities to which each requirement applies, (3) any compliance deadlines mentioned, and (4) any penalties or consequences for non-compliance. Return the output as a structured JSON array with one entry per requirement." For documents that include scanned pages, first route them through granite-vision-4.1-4b to extract text and table content before passing to the 30B model for compliance analysis. Pass all user-facing outputs through granite-guardian-4.1-8b to screen for sensitive information before returning results. NVIDIA: Nemotron-3-Nano-Omni-30B-A3B-Reasoning-FP8 Model Specs Parameters / size: 31B total, ~3B activated per forward pass (Mamba2-Transformer Hybrid Mixture-of-Experts) Context length: 256,000 tokens Primary task: Video-audio-image-text-to-text (Multimodal understanding, reasoning, tool calling) Why it's interesting Multimodal input from a single efficient endpoint: Nemotron-3-Nano-Omni-30B-A3B-Reasoning supports video (up to 2 minutes), audio (up to 1 hour), images (RGB), and text—all from a single model deployed in Microsoft Foundry. Three variants are available in Foundry: full-precision BF16, FP8, and NVFP4. Paper: Nemotron Nano Omni technical report. Strong results across vision, document, video, and audio benchmarks: With reasoning mode enabled, the model scores 82.8 on MathVista-MINI (visual math reasoning), 67.04 on OCRBenchV2-EN (document OCR), 63.6 on Charxiv Reasoning (chart understanding), 72.2 on Video MME (video Q&A), 74.52 on Daily Omni (video+audio omnimodal understanding), and 89.39 on VoiceBench (speech instruction following). On OSWorld (GUI agent benchmark measuring autonomous computer use), it scores 47.4—a notable result for a model at the 3B active parameter scale. (Please see above model cards for further benchmark data) Mamba2-Transformer Hybrid MoE for efficient long-context inference: The model's layers alternate between Mamba2 state-space blocks (which process sequences with linear rather than quadratic cost) and standard Transformer attention blocks, combined with Mixture-of-Experts feedforward layers. Only ~3B parameters are activated per token despite the 31B total, making the 256K context window practically usable at lower compute cost than a comparably sized dense model. Word-level timestamps, JSON output, and tool calling for structured media workflows: The model produces word-level timestamps from audio, enabling precise transcript-to-timecode alignment for review and indexing workflows. Combined with JSON-structured output, chain-of-thought reasoning, and native tool calling, it can serve as an agentic step that ingests raw media (meeting recordings, M&E assets, training videos) and produces structured outputs for downstream systems without requiring separate transcription or OCR preprocessing stages. Try it Use Case Prompt Pattern Meeting intelligence Submit audio recording (up to 1 hr); extract transcript with word-level timestamps, action items, and decisions as structured JSON Video content analysis Submit video clip (up to 2 min) + query; retrieve timestamped summary of key events or spoken content Document + audio joint analysis Submit scanned document image alongside narrated walkthrough audio; extract and reconcile information from both modalities Multimodal tool calling Provide tool definitions + combined image/audio input; model reasons over content and executes structured tool calls Sample prompt for a media and compliance deployment: You are building a broadcast compliance review system for a media company. Using the Nemotron-3-Nano-Omni-30B-A3B-Reasoning-FP8 endpoint deployed in Microsoft Foundry, submit each recorded segment as video input with the following instruction: "Review this video segment and produce a compliance report as a JSON object with the following fields: transcript (full text with word-level timestamps), flagged_segments (array of objects with start_time, end_time, content, and reason for flagging), speaker_count (estimated number of distinct speakers), and compliance_summary (overall assessment). Flag any content that includes unverified factual claims, restricted product categories, or regulatory disclosures that may be incomplete." Use the word-level timestamps from the compliance report to route flagged segments directly to the editorial review queue with precise timecode references. Qwen: Qwen3.6-35B-A3B Model Specs Parameters / size: 35B total, 3B activated (Mixture-of-Experts) Context length: 262,144 tokens natively, extensible to 1,010,000 tokens Primary task: Image-text-to-text (agentic coding, reasoning, vision) Why it's interesting Agentic coding improvements over Qwen3.5-35B-A3B: Qwen3.6-35B-A3B scores 73.4 on SWE-bench Verified (vs. 70.0 for Qwen3.5-35B-A3B and 52.0 for Gemma 4 31B), 67.2 on SWE-bench Multilingual (vs. 60.3 and 51.7), and 49.5 on SWE-bench Pro (vs. 44.6 and 35.7). Terminal-Bench 2.0 reaches 51.5 (vs. 40.5 and 42.9). The update targets frontend workflows and repository-level reasoning specifically, areas where earlier Qwen3.5 iterations showed gaps. Blog post: Qwen3.6-35B-A3B. Hybrid architecture: Gated DeltaNet and Mixture-of-Experts: The model's 40 layers alternate between Gated DeltaNet blocks (a form of linear attention that avoids the quadratic cost of standard self-attention), Gated Attention blocks (using Grouped Query Attention with 16 query heads and 2 key-value heads), and Mixture-of-Experts (MoE) feedforward layers with 256 experts (8 routed + 1 shared active per token). Only 3B parameters are activated per forward pass, keeping inference cost comparable to a 3B dense model while retaining the capacity of a 35B model for knowledge and specialization. Thinking preservation across conversation turns: Qwen3.6 introduces an option to retain reasoning context from previous messages in multi-turn conversations. In prior models, chain-of-thought traces were stripped between turns, requiring the model to re-derive context it had already reasoned through. With thinking preservation enabled, iterative coding workflows—such as debugging across multiple exchanges—benefit from accumulated reasoning without repeating earlier analysis. Natively extensible to 1 million token context: The 262K native context is already among the largest in open models at this size, and the architecture supports extension to 1,010,000 tokens. On GPQA Diamond (science reasoning), Qwen3.6-35B-A3B scores 86.0—above both Gemma 4 31B (84.3) and Qwen3.5-27B (85.5)—while matching Gemma 4 31B on MMLU Pro (85.2) and LiveCodeBench v6 (80.4 vs. 80.0). Try it Use Case Prompt Pattern Repository-level code change Provide repository structure + task description; model plans file edits and outputs unified diff Multi-turn iterative debugging Enable thinking preservation; submit failing test + code across multiple turns; accumulate reasoning context Frontend code generation Provide design spec or screenshot + existing codebase context; generate component implementation Long-document reasoning Submit technical specification (up to 262K tokens); ask model to identify ambiguities or implementation gaps Sample prompt for a software engineering deployment: You are building an automated code review and implementation assistant for a platform engineering team. Using the Qwen3.6-35B-A3B endpoint deployed in Microsoft Foundry, enable thinking preservation for multi-turn sessions. In the first turn, submit the repository file tree and a GitHub issue describing a required API endpoint change. Prompt the model: "Review the repository structure and describe your implementation plan, including which files need to change and why." In the second turn, submit the relevant source files and prompt: "Based on your earlier plan, implement the changes and produce a unified diff." In the third turn, submit the test suite and prompt: "Write additional unit tests for the new endpoint, covering edge cases identified in your reasoning." The thinking preservation feature ensures the model carries forward its understanding of the codebase across all three turns without re-explaining context.

OpenAI's GPT-5.5 Instant (or Chat-latest in the API) begins rolling out in Microsoft Foundry today as GPT-chat-latest. Built on GPT-5.4 and GPT-5.3-chat, the new model delivers measurable gains in factual accuracy, tool calling, and response efficiency. These improvements translate directly into more reliable production deployments. GPT-chat-latest is designed for the workflows builders are actually shipping: multi-turn assistants, agentic systems that orchestrate tools, and retrieval-grounded applications where precision and grounding matter as much as conversational quality. Why the name is changing In Microsoft Foundry, we are introducing GPT-chat-latest as the product name for this release, while the model continues to follow the existing Preview lifecycle and standard notice periods. We are also evaluating ways to simplify how customers access continuously updated models over time, but current behavior remains unchanged as that work continue Smarter, more factually reliable GPT-chat-latest closes the factuality gap from prior iterations with significant reductions in hallucinations, especially in domains where accuracy matters most. According to OpenAI, the new model produces 52.5% fewer hallucinations and reduces hallucinated claims by 37.3% on conversations previously flagged for factual errors when compared to GPT-5.3-chat. These gains extend beyond text. GPT-chat-latest shows improvements in visual reasoning, expert multimodal understanding, and STEM tasks, with measurable lifts across standard benchmarks: Benchmark GPT-5.3-chat GPT-chat-latest CharXiv-reasoning Scientific Chart Reasoning 75.0 81.6 MMMU-Pro Expert multimodal reasoning 69.2 76.0 GPQA PhD-level science questions 78.5 85.6 AIME 2025 Competition math 65.4 81.2 *Data shown comes from OpenAI’s testing” For builders shipping into regulated workloads such as clinical decision support, legal research, financial advisory, and technical analysis, these improvements raise the bar on the kinds of applications GPT-chat-latest can assist with. More efficient outputs GPT-chat-latest produces responses that may be more to-the-point without losing substance. The model may reduce verbosity and over formatting, ask fewer follow-up questions, and avoid cluttered output patterns that often require post-processing in production UIs. For builders, this can translate to two concrete benefits: lower output token costs at scale, and cleaner responses that drop into product surfaces with less downstream cleanup. In comparative testing from OpenAI, GPT-chat-latest produced roughly 25–30% fewer words than GPT-5.3-chat across a range of common prompts while preserving response quality, and in many cases improving it. Improving intelligence and tool calling GPT-chat-latest introduces measurable improvements in how the model interacts with tools, including better judgment about when and how to invoke them. The model produces more structured and context-aware tool invocation outputs, which is particularly relevant for workflows that rely on function calling, retrieval-augmented generation, and multi-step reasoning. Equally important, the model is better at deciding whether a tool is needed in the first place, reducing unnecessary tool calls in scenarios where it already has the information to answer directly. Improved search and context handling GPT-chat-latest includes targeted improvements to how the model retrieves, interprets, and synthesizes information when search is involved, with enhancements to query formulation, result ranking, and filtering, plus more grounded synthesis of retrieved content into final responses. These changes improve handling of ambiguous or underspecified queries and reduce noise in answers that depend on retrieved content. The model also makes better use of the context developers pass in, including system prompts, conversation history, retrieved documents, and structured data. Applications that maintain long-running state or stitch together multiple retrieval steps produce more coherent, context-aware outputs without developers having to over-engineer prompt scaffolding. Use Cases: When to choose the chat model Developers typically choose a chat-optimized model like GPT-5.5-chat when the application needs to sustain multi-turn conversations while reliably following instructions and coordinating external tools. This is a fit for assistants and agentic workflows where the model must interpret user intent over time, decide when to retrieve additional context, and produce structured outputs for downstream systems rather than just generate free-form text. Customer support and contact centers: virtual agents that maintain conversational context across a case, retrieve policy or product documentation via search, and hand off to a ticketing or CRM system through tool calls when escalation is needed. Retail and e-commerce: shopping and service assistants that clarify preferences over multiple turns, reference catalogs and policies via retrieval, and generate structured actions such as returns, exchanges, and order lookups through integrated tools. Manufacturing and field service: technician-facing assistants that combine conversational guidance with retrieval of manuals and work instructions, plus structured task creation in maintenance systems. Use GPT-chat-latest Use GPT-5.5 Reasoning Multi-turn assistants and customer-facing chat experiences Harder problems that benefit from more deliberate, step-by-step thinking Agentic workflows that coordinate tools (search, retrieval, ticketing, CRM) and benefit from structured tool outputs Complex analysis, planning, or decision support where correctness matters more than conversational flow Interactive experiences where you want quick back-and-forth clarification and task completion Tasks involving multi-constraint reasoning (policy interpretation, detailed requirements, long-horizon plans) RAG-based apps where the model must decide when to retrieve and then synthesize grounded answers Offline or low-tool scenarios where the main value is deeper reasoning over provided context Pricing Model Input ($/1M tokens) Cached input ($/1M tokens) Output ($/1M tokens) GPT-chat-latest $5 $0.50 $30 Responsible AI in Microsoft Foundry At Microsoft, our mission to empower people and organizations remains constant.

Take a small design team running a global social campaign. They have the creative vision to produce localized imagery for every market, but not the resources to reshoot, reformat, or outsource that scale. Every asset needs to fit a different platform, a different dimension, a different cultural context, and they all need to ship at the same time. This is where flexible image generation comes in handy. OpenAI's GPT-image-2 is now generally available and rolling out today to Microsoft Foundry, introducing a step change in image generation. Developers and designers now get more control over image output, so a small team can execute with the reach and flexibility of a much larger one. What is new in GPT-image-2? GPT-image-2 brings real world intelligence, multilingual understanding, improved instruction following, increased resolution support, and an intelligent routing layer giving developers the tools to scale image generation for production workflows. Real world intelligence GPT-image-2 has a knowledge cut off of December 2025, meaning that it is able to give you more contextually relevant and accurate outputs. The model also comes with enhanced thinking capabilities that allow it to search the web, check its own outputs, and create multiple images from just one prompt. These enhancements shift image generation models away from being simple tools and runs them into creative sidekicks. Multilingual understanding GPT-image-2 includes increased language support across Japanese, Korean, Chinese, Hindi, and Bengali, as well as new thinking capabilities. This means the model can create images and render text that feels localized. Increased resolution support GPT-image-2 introduces 4K resolution support, giving developers the ability to generate rich, detailed, and photorealistic images at custom dimensions. Resolution guidelines to keep in mind: Constraint Detail Total pixel budget Maximum pixels in final image cannot exceed 8,294,400 Minimum pixels in final image cannot be less than 655,360 Requests exceeding this are automatically resized to fit. Resolutions 4K, 1024x1024, 1536x1024, and 1024x1536 Dimension alignment Each dimension must be a multiple of 16 Note: If your requested resolution exceeds the pixel budget, the service will automatically resize it down. Intelligent routing layer GPT-image-2 also includes an expanded routing layer with two distinct modes, allowing the service to intelligently select the right generation configuration for a request without requiring an explicitly set size value. Mode 1 — Legacy size selection In Mode 1, the routing layer selects one of the three legacy size tiers to use for generation: Size tier Description smimage Small image output image Standard image output xlimage Large image output This mode is useful for teams already familiar with the legacy size tiers who want to benefit from automatic selection without making any manual changes. Mode 2 — Token size bucket selection In Mode 2, the routing layer selects from six token size buckets — 16, 24, 36, 48, 64, 96 — which map roughly to the legacy size tiers: Token bucket Approximate legacy size 16, 24 smimage 36, 48 image 64, 96 xlimage This approach can allow for more flexibility in the number of tokens generated, which in turn helps to better optimize output quality and efficiency for a given prompt. See it in action GPT-image-2 shows improved image fidelity across visual styles, generating more detailed and refined images. But, don’t just take our word for it, let's see the model in action with a few prompts and edits. Here is the example we used: Prompt: Interior of an empty subway car (no people). Wide-angle view looking down the aisle. Clean, modern subway car with seats, poles, route map strip, and ad frames above the windows. Realistic lighting with a slight cool fluorescent tone, realistic materials (metal poles, vinyl seats, textured floor). As you can see, when using the same base prompt, the image quality and realism improved with each model. Now let’s take a look at adding incremental changes to the same image: Prompt: Populate the ad frames with a cohesive ad campaign for “Zava Flower Delivery” and use an array of flower types. And our subway is now full of ads for the new ZAVA flower delivery service. Let's ask for another small change: Prompt: In all Zava Flower Delivery advertisements, change the flowers shown to roses (red and pink roses). And in three simple prompts, we've created a mockup of a flower delivery ad. From marketing material to website creation to UX design, GPT-image-2 now allows developers to deliver production-grade assets for real business use cases. Image generation across industries These new capabilities open the door to richer, more production-ready image generation workflows across a range of enterprise scenarios: Retail & e-commerce: Generate product imagery at exact platform-required dimensions, from square thumbnails to wide banners, without post-processing. Marketing: Produce crisp, rich in color campaign visuals and social assets localized to different markets. Media & entertainment: Generate storyboard panels and scene at resolutions suited to production pipelines. Education & training: Create visual learning aids and course materials formatted to exact display requirements across devices. UI/UX design: Accelerate mockup and prototype workflows by generating interface assets at the precise dimensions your design system requires. Trust and safety At Microsoft, our mission to empower people and organizations remains constant. As part of this commitment, models made available through Foundry undergo internal reviews and are deployed with safeguards designed to support responsible use at scale. Learn more about responsible AI at Microsoft. For GPT-image-2, Microsoft applied an in-depth safety approach that addresses disallowed content and misuse while maintaining human oversight. The deployment combines OpenAI’s image generation safety mitigations with Azure AI Content Safety, including filters and classifiers for sensitive content.

Automate Prior Authorization with AI Agents - Now Available as a Foundry Template
By Amit Mukherjee · Principal Solutions Engineer, Microsoft Health & Life Sciences Lindsey Craft-Goins · Technology Leader - Cloud & AI Platforms, Health & Life Sciences Joel Borellis · Director Solutions Engineering - Cloud & AI Platforms, Health & Life Sciences Prior authorization (PA) is one of the most expensive bottlenecks in U.S. healthcare. Physicians complete an average of 39 PA requests per week, spending roughly 13 hours of physician-and-staff time on PA-related work (AMA 2024 Prior Authorization Physician Survey). Turnaround averages 5–14 business days, and PA alone accounts for an estimated $35 billion in annual administrative spending (Sahni et al., Health Affairs Scholar, 2024). The regulatory clock is now ticking. CMS-0057-F mandates electronic PA with 72-hour urgent response starting in 2026. Forty-nine states plus DC already have PA laws on the books, and at least half of all U.S. state legislatures introduced new PA reform bills this year, including laws specifically targeting AI use in PA decisions (KFF Health News, April 2026). Today we’re making the Prior Authorization Multi-Agent Solution Accelerator available as a Microsoft Foundry template. Health plan payers can deploy a working, four-agent PA review pipeline to Azure using the Azure Developer CLI (“azd”) with a single command in supported environments, then customize it to their policies, workflows, and EHR environment. Try it now: Find the template in the Foundry template gallery, or clone directly from github.com/microsoft/Prior-Authorization-Multi-Agent-Solution-Accelerator What the template delivers The accelerator deploys four specialist Foundry hosted agents (Compliance, Clinical Reviewer, Coverage, and Synthesis), each independently containerized and managed by Foundry. In internal testing with synthetic demo cases, the pipeline reduced review workflow, from beginning to completion in under 5 minutes per case. Agent Role Key capability Compliance Documentation check 10-item checklist with blocking/non-blocking flags Clinical Reviewer Clinical evidence ICD-10 validation, PubMed + ClinicalTrials.gov search Coverage Policy matching CMS NCD/LCD lookup, per-criterion MET/NOT_MET mapping Synthesis Decision rubric 3-gate APPROVE/PEND with weighted confidence scoring Compliance and Clinical run in parallel. Coverage runs after clinical findings are ready. Synthesis evaluates all three outputs through a three-gate rubric. The result is a structured recommendation with per-criterion confidence scores and a full audit trail, not a black-box answer. Solution architecture The accelerator runs entirely on Azure. The frontend and backend deploy as Azure Container Apps. The four specialist agents are hosted by Microsoft Foundry. Real-time healthcare data flows through third-party MCP servers. Figure 1: Azure solution architecture How the pipeline works The four agents execute in a structured parallel-then-sequential pipeline. Compliance and Clinical run simultaneously in Phase 1. Coverage runs after clinical findings are ready. The Synthesis agent applies a three-gate decision rubric over all prior outputs. Figure 2: Agentic architecture, hosted agent pipeline Compliance and Clinical run in parallel via asyncio.gather, since neither depends on the other. Coverage runs sequentially after Clinical because it needs the structured clinical profile for criterion mapping. Synthesis evaluates all three outputs through a three-gate rubric (Provider, Codes, Medical Necessity) with weighted confidence scoring: 40% coverage criteria + 30% clinical extraction + 20% compliance + 10% policy match. The total pipeline time is bound by the slowest parallel agent plus the sequential agents, not the sum. In internal testing with synthetic demo cases, this architecture indicated materially reduced processing time compared to sequential manual workflows. Under the hood For the architect in the room, here are four design decisions worth knowing about: Foundry hosted agents: Each agent is independently containerized, versioned, and managed by Foundry’s runtime. The FastAPI backend is a pure HTTP dispatcher. All reasoning happens inside the agent containers, and there are no code changes between local (Docker Compose) and production (Foundry); the environment variable is the only switch. Structured output: Every agent uses MAF’s response_format enforcement to produce typed Pydantic schemas at the token level. No JSON parsing, no malformed fences, no free-form text. The orchestrator receives typed Python objects; the frontend receives a stable API contract. Keyless security: DefaultAzureCredential throughout, so no API keys are stored anywhere. Managed Identity handles production; azd tokens handle local development. Role assignments are provisioned automatically by Bicep at deploy time. Observability: All agents emit OpenTelemetry traces to Azure Application Insights. The Foundry portal shows per-agent spans correlated by case ID. End-to-end latency, per-agent contribution, and error rates are visible from day one with no additional configuration. For the full architecture documentation, agent specifications, Pydantic schemas, and extension guides, see the GitHub repository. Why this matters now Human-in-the-loop by design The system runs in LENIENT mode by default: it produces only APPROVE or PEND and is not designed to produce automated DENY outcomes in its default configuration. Every recommendation requires a clinician to Accept or Override with documented rationale before the decision is finalized. Override records flow to the audit PDF, notification letters, and downstream systems. This directly addresses the emerging wave of state legislation governing AI use in PA decisions. Domain experts own the rules Agent behavior is defined in markdown skill files, not Python code. When CMS updates a coverage determination or a plan changes its commercial policy, a clinician or compliance officer edits a text file and redeploys. No engineering PR required.

Vector Drift in Azure AI Search: Three Hidden Reasons Your RAG Accuracy Degrades After Deployment
What Is Vector Drift? Vector drift occurs when embeddings stored in a vector index no longer accurately represent the semantic intent of incoming queries. Because vector similarity search depends on relative semantic positioning, even small changes in models, data distribution, or preprocessing logic can significantly affect retrieval quality over time. Unlike schema drift or data corruption, vector drift is subtle: The system continues to function Queries return results But relevance steadily declines Cause 1: Embedding Model Version Mismatch What Happens Documents are indexed using one embedding model, while query embeddings are generated using another. This typically happens due to: Model upgrades Shared Azure OpenAI resources across teams Inconsistent configuration between environments Why This Matters Embeddings generated by different models: Exist in different vector spaces Are not mathematically comparable Produce misleading similarity scores As a result, documents that were previously relevant may no longer rank correctly. Recommended Practice A single vector index should be bound to one embedding model and one dimension size for its entire lifecycle. If the embedding model changes, the index must be fully re-embedded and rebuilt. Cause 2: Incremental Content Updates Without Re-Embedding What Happens New documents are continuously added to the index, while existing embeddings remain unchanged. Over time, new content introduces: Updated terminology Policy changes New product or domain concepts Because semantic meaning is relative, the vector space shifts—but older vectors do not. Observable Impact Recently indexed documents dominate retrieval results Older but still valid content becomes harder to retrieve Recall degrades without obvious system errors Practical Guidance Treat embeddings as living assets, not static artifacts: Schedule periodic re-embedding for stable corpora Re-embed high-impact or frequently accessed documents Trigger re-embedding when domain vocabulary changes meaningfully Declining similarity scores or reduced citation coverage are often early signals of drift. Cause 3: Inconsistent Chunking Strategies What Happens Chunk size, overlap, or parsing logic is adjusted over time, but previously indexed content is not updated. The index ends up containing chunks created using different strategies. Why This Causes Drift Different chunking strategies produce: Different semantic density Different contextual boundaries Different retrieval behavior This inconsistency reduces ranking stability and makes retrieval outcomes unpredictable. Governance Recommendation Chunking strategy should be treated as part of the index contract: Use one chunking strategy per index Store chunk metadata (for example, chunk_version) Rebuild the index when chunking logic changes Design Principles Versioned embedding deployments Scheduled or event-driven re-embedding pipelines Standardized chunking strategy Retrieval quality observability Prompt and response evaluation Key Takeaways Vector drift is an architectural concern, not a service defect It emerges from model changes, evolving data, and preprocessing inconsistencies Long-lived RAG systems require embedding lifecycle management Azure AI Search provides the controls needed to mitigate drift effectively Conclusion Vector drift is an expected characteristic of production RAG systems. Teams that proactively manage embedding models, chunking strategies, and retrieval observability can maintain reliable relevance as their data and usage evolve. Recognizing and addressing vector drift is essential to building and operating robust AI solutions on Azure.

Stay connected to our developer community on Discord and stay up to date on what is new in Foundry through the Model Mondays series.Now in Foundry: Microsoft Harrier and NVIDIA EGM-8B
This week's Model Mondays edition highlights three models that share a common thread: each achieves results comparable to larger leading models, as a result of targeted training strategies rather than scale. Microsoft Research's harrier-oss-v1-0.6b from achieves state-of-the-art results on the Multilingual MTEB v2 embedding benchmark at 0.6B parameters through contrastive learning and knowledge distillation. NVIDIA's EGM-8B scores 91.4 average IoU on the RefCOCO visual grounding benchmark by training a small Vision Language Model (VLM) with reinforcement learning to match the output quality of much larger models. Together they represent a practical argument for efficiency-first model development: the gap between small and large models continues to narrow when training methodology is the focus rather than parameter count alone. Models of the week Microsoft Research: harrier-oss-v1-0.6b Model Specs Parameters / size: 0.6B Context length: 32,768 tokens Primary task: Text embeddings (retrieval, semantic similarity, classification, clustering, reranking) Why it's interesting State-of-the-art on Multilingual MTEB v2 from Microsoft Research: harrier-oss-v1-0.6b is a new embedding model released by Microsoft Research, achieving a 69.0 score on the Multilingual MTEB v2 (Massive Text Embedding Benchmark) leaderboard—placing it at the top of its size class at release. It is part of the harrier-oss family spanning harrier-oss-v1-270m (66.5 MTEB v2), harrier-oss-v1-0.6b (69.0), and harrier-oss-v1-27b (74.3), with the 0.6B variant further trained with knowledge distillation from the larger family members. Benchmarks: Multilingual MTEB v2 Leaderboard. Decoder-only architecture with task-instruction queries: Unlike most embedding models that use encoder-only transformers, harrier-oss-v1-0.6b uses a decoder-only architecture with last-token pooling and L2 normalization. Queries are prefixed with a one-sentence task instruction (e.g., "Instruct: Retrieve relevant passages that answer the query\nQuery: ...") while documents are encoded without instructions—allowing the same deployed model to be specialized for retrieval, classification, or similarity tasks through the prompt alone. Broad task coverage across six embedding scenarios: The model is trained and evaluated on retrieval, clustering, semantic similarity, classification, bitext mining, and reranking—making it suitable as a general embedding backbone for multi-task pipelines rather than a single-use retrieval model. One endpoint, consistent embeddings across the stack. 100+ language support: Trained on a large-scale mixture of multilingual data covering Arabic, Chinese, Japanese, Korean, and 100+ additional languages, with strong cross-lingual transfer for tasks that span language boundaries. Try it Use Case Prompt Pattern Multilingual semantic search Prepend task instruction to query; encode documents without instruction; rank by cosine similarity Cross-lingual document clustering Embed documents across languages; apply clustering to group semantically related content Text classification with embeddings Encode labeled examples + new text; classify by nearest-neighbor similarity in embedding space Bitext mining Encode parallel corpora in source and target languages; align segments by embedding similarity Sample prompt for a global enterprise knowledge base deployment: You are building a multilingual internal knowledge base for a global professional services firm. Using the harrier-oss-v1-0.6b endpoint deployed in Microsoft Foundry, encode all internal documents—policy guides, project case studies, and technical documentation—across English, French, German, and Japanese. At query time, prepend the task instruction to each employee query: "Instruct: Retrieve relevant internal documents that answer the employee's question\nQuery: {question}". Retrieve the top-5 most similar documents by cosine similarity and pass them to a language model with the instruction: "Using only the provided documents, answer the question and cite the source document title for each claim. If no document addresses the question, say so." NVIDIA: EGM-8B Model Specs Parameters / size: ~8.8B Context length: 262,144 tokens Primary task: Image-text-to-text (visual grounding) Why it's interesting Preforms well on visual grounding compared to larger models even at its small size: EGM-8B achieves 91.4 average Intersection over Union (IoU) on the RefCOCO benchmark—the standard measure of how accurately a model localizes a described region within an image. Compared to its base model Qwen3-VL-8B-Thinking (87.8 IoU), EGM-8B achieves a +3.6 IoU gain through targeted Reinforcement Learning (RL) fine-tuning. Benchmarks: EGM Project Page. 5.9x faster than larger models at inference: EGM-8B achieves 737ms average latency. The research demonstrates that test-time compute can be scaled horizontally across small models—generating many medium-quality responses and selecting the best—rather than relying on a single expensive forward pass through a large model. Two-stage training: EGM-8B is trained first with Supervised Fine-Tuning (SFT) on detailed chain-of-thought reasoning traces generated by a proprietary VLM, then refined with Group Relative Policy Optimization (GRPO) using a reward function combining IoU accuracy and task success. The intermediate SFT checkpoint is available as nvidia/EGM-8B-SFT for developers who want to experiment with the intermediate stage. Addresses a root cause of small model grounding errors: The EGM research identifies that 62.8% of small model errors on visual grounding stem from complex multi-relational descriptions—where a model must reason about spatial relationships, attributes, and context simultaneously. By focusing test-time compute on reasoning through these complex prompts, EGM-8B closes the gap without increasing the underlying model size. Try it Use Case Prompt Pattern Object localization Submit image + natural language description; receive bounding box coordinates Document region extraction Provide scanned document image + field description; extract specific regions Visual quality control Submit product image + defect description; localize defect region for downstream classification Retail shelf analysis Provide shelf image + product description; return location of specified SKU Sample prompt for a retail and logistics deployment: You are building a visual inspection system for a logistics warehouse. Using the EGM-8B endpoint deployed in Microsoft Foundry, submit each incoming package scan image along with a natural language grounding query describing the region of interest: "Please provide the bounding box coordinate of the region this sentence describes: {description}". For example: "the label on the upper-left side of the box", "the barcode on the bottom face", or "the damaged corner on the right side". Use the returned bounding box coordinates to route each package to the appropriate inspection station based on the identified region.

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.
