Today at Ignite 2025, the spotlight shone brightly on Microsoft Foundry the unified AI platform empowering enterprises to build, deploy, and govern intelligent agents at scale. New features released today are designed to enhance model accessibility, agent sophistication, and enterprise-grade reliability. Below is a deep dive into these powerful updates.
Anthropic’s Claude Models Join Foundry
Microsoft Foundry customers can now access three Claude models: Claude Sonnet 4.5, Claude Opus 4.1, and Claude Haiku 4.5. These frontier AI models bring specialized capabilities to Foundry users, including advanced code generation, complex reasoning with ultra-long context (up to 1 million tokens), and robust tool-use skills. Critically, the addition of Claude means Azure becomes the only cloud platform to offer customers both OpenAI’s GPT series and Anthropic’s Claude models side-by-side, giving enterprises unprecedented flexibility to choose the optimal model for each use case.
Foundry Models: Unparalleled Choice and Performance
Ignite revealed major enhancements in the Foundry Models suite, empowering organizations with:
- Broader model catalog: Over 11,000 models now available including frontier generators and specialized AI from Anthropic, Cohere, NVIDIA, RosettaFold, MongoDB’s Voyage AI, and more.
- Model Router (GA): Automatically selects the best model for each prompt based on real-time checks for latency, quality, and cost. Benchmarks show up to 50% latency reduction, saving time and money.
- Priority Processing (Public Preview): SLA-backed, low-latency inference lanes for critical workloads using GPT‑4.1, with promising additions like GPT‑5 on the horizon.
- Fine-Tuning: Preview tools that allow custom tuning using synthetic data, adapter layers, and community-hosted models—ranging from Ministral 3B to Llama 3.3—enable tailored enterprise intelligence.
- Synthetic Data Generation (Preview): Generate Synthetic Data within Microsoft Foundry for fine-tuning by providing sample data. More information on this available here Generate synthetic data with Microsoft Foundry (Preview) - Microsoft Foundry | Microsoft Learn
- Knowledge: Provides a single endpoint that connects agents to multiple knowledge sources Azure Blob, OneLake, SharePoint, Azure AI Search indexes, the web (via Bing), and more without needing separate RAG pipelines for each agent.
Next‑Gen Agent Hosting with Foundry Agent Service
Foundry Agent Service received significant enhancements that elevate intelligent agent development and deployment:
- Hosted Agents (Public Preview): Deploy agents built with Microsoft Agent Framework, LangGraph, or other third-party tools directly into a fully managed runtime no container orchestration needed.
- Multi-Agent Workflows (Public Preview): Visually design and program multi-step, collaborative agent workflows. Ideal for complex tasks like onboarding or finance approvals, with built-in fault recovery and orchestration.
- Built-in Memory (Public Preview): Agents now persist context securely across sessions. Developers define memory scope, while Access is governed via Entra ID, ensuring session continuity without compromising data isolation.
- Foundry Tools (Public Preview): A catalog of 1,000+ prebuilt and private connectors (MCP, OpenAPI) and even and Browser Automation for UI based tasks. Agents can securely call business systems like SAP, UiPath, and much more.
OpenAPI, MCP, and A2A Integrations available in Foundry as Custom tools
- Foundry IQ (Public Preview): Integrates Azure AI Search to provide agents with RAG-powered access to enterprise sources (SharePoint, ADLS, web), enforcing Purview security policies automatically.
- Agent Evaluation: enables developers to benchmark and validate agent performance across tasks using automated metrics, custom test sets, and real-world scenarios ensuring reliability and continuous improvement.
Enterprise Confidence with Foundry Control Plane
Security, compliance, and governance the hallmarks of any enterprise-grade platform are front and center in today’s announcements:
- Foundry Control Plane (Public Preview): Centralizes identity (Entra Agent ID), policy enforcement, observability, and risk control. Includes safeguards for inputs, outputs, tool calls, and prompt hygiene.
- Deeper integrations: Defender and Purview enrich agent telemetry. GitHub Advanced Security + Defender for Cloud bring dev-to-production safety.
- AI Gateway: an essential part of Microsoft Foundry for enforcing enterprise grade governance, usage control, and observability across model and agent interactions.
- One-click Agent 365 publication: Simplified deployment path from Foundry Agent Service into Microsoft 365 Copilot and Teams managed intelligently via Agent 365 in the Admin Center.
Enterprises gain a unified control plane to manage AI agents across development, production, and deployment ensuring trust, visibility, and fault-free governance.
Hybrid AI: Local, Cloud & Edge for Maximum Reach
Now with Microsoft Foundry’s, Teams can deploy AI experiences everywhere from cloud to edge to on-device ensuring performance, privacy, and resilience regardless of connectivity.
- Foundry Local expanded: Now in private preview on Android, joining Windows and macOS support.
- Managed Instance on Azure App Service (Public Preview): Enables .NET apps to migrate easily, tapping into Foundry’s model, tool, and governance stack.
Looking Ahead
Today’s Ignite announcements make Microsoft Foundry a robust platform for enterprise intelligence bringing model diversity, rich agent orchestration, strong governance, and hybrid deployment flexibility.
Enterprises now have a mature foundation to:
- Experiment across best-in-class AI models,
- Seamlessly embed agents into business processes,
- Maintain robust control through centralized governance, and
- Empower users regardless of device or deployment environment.
Foundry’s full stack from models to control plane becomes a key enabler of scalable, secure, and intelligent transformation. With these layered improvements from model innovation to multi-agent workflows, from on-device edge support to unified governance Foundry is well-positioned to lead enterprises into a new era of purposeful AI.
