Microsoft Foundry Revolutionizes Enterprise AI with Unified Architecture and Advanced Claude Models
November 30, 2025
Microsoft Foundry is a production-grade, end-to-end enterprise AI platform that unifies models, agents, IQ, and a control plane to treat AI as an integrated architecture rather than isolated tools.
Foundry Agent Service uses Claude as the reasoning core to enable multi-step workflows, data integration via the Model Context Protocol, automatic routing to Claude variants, and governance for managing agent fleets.
The platform supports moving from responsive AI to actionable AI, enabling single agents, teams, or multi-step workflows and integrates with the Microsoft Agent Framework for unified development.
Claude variants are priced for Global Standard deployment in East US 2 and West US, with Haiku 4.5 at $1 per 1 million input tokens and $5 per 1 million output tokens, Sonnet 4.5 at $3/$15, and Opus 4.1 at $15/$75.
Deep Research extends Claude’s reasoning by pulling live information, comparing with internal data, and producing context-grounded insights with source grounding.
A real-time optimization layer dynamically routes tasks to the most efficient models to reduce latency, improve accuracy, and optimize resource use.
Centralized management tools provide real-time monitoring, enhanced security, and streamlined oversight to support compliance and operational efficiency.
Readers are invited to explore Claude in Foundry, with links to start building and Ignite event registrations for more announcements.
Developer experience includes a consistent UX across web experimentation, SDKs for Python and C#, REST APIs, GitHub workflows, Visual Studio integration, and templates to accelerate production deployment.
Defender for Cloud integrates with GitHub Advanced Security to deliver AI-suggested fixes inside GitHub and real-time security tracking in Defender for Cloud for secure AI systems.
Claude models—Haiku 4.5, Sonnet 4.5, and Opus 4.1—are enterprise-ready, designed for fast experiences, complex agents, and specialized reasoning, all built on Constitutional AI for safety.
Azure AI adoption is widespread, with more than 60,000 organizations using Azure AI and many leveraging Foundry to automate complex processes and scale intelligent agents.
