In the field of artificial intelligence, Anthropic has announced today an expanded strategic partnership with Microsoft. The company's three Claude AI models — Sonnet4.5, Haiku4.5, and Opus4.1 — have officially launched on the Microsoft Foundry platform and are now in public beta testing. Azure customers can now use these powerful AI models through the Foundry platform to build enterprise-level production applications and intelligent agents, fully leveraging the advantages of the Microsoft ecosystem.

The biggest highlight of this collaboration is that enterprises can easily deploy Claude models within their familiar Microsoft environment, applying them to multiple fields including code development and smart office work. Developers can also use Claude Code, an AI coding assistant, to enhance the level of automation in project development within Microsoft Foundry. At the same time, Microsoft 365 Copilot has also achieved the original integration of Claude, such as the Researcher multi-step research agent in Copilot Studio, and user-customizable AI agent features. In addition, the Agent Mode in Microsoft Excel now supports calling Claude, allowing users to directly generate formulas, analyze data, identify errors, and optimize solutions within Excel.

For enterprise users who have already deeply invested in Microsoft Foundry and 365 Copilot, these integrations simplify the AI procurement process. Users no longer need to sign or settle separately with multiple vendors, greatly reducing deployment cycles. The deployment of Claude on Foundry uses serverless technology, managed by Anthropic, and developers can quickly go live through the APIs and tools on the Foundry platform to start building projects. The platform supports various APIs, development tools, and workflows, and seamlessly integrates with Azure protocols, suitable for Azure Consumption Commitment (MACC), and can be directly incorporated into existing billing systems without separate approval.

Claude models also support access through multiple programming languages, including Python, TypeScript, and C# SDK, and are compatible with Microsoft Entra authentication. Currently, the Claude models have been officially launched in global standard deployments and are billed according to standard API pricing. It is expected that the U.S. local data center will also be launched soon. For different application scenarios, Microsoft customers can flexibly choose the cutting-edge models of Claude: Sonnet4.5 is suitable for complex reasoning and autonomous programming, Haiku4.5 is the best choice for high-concurrency applications, and Opus4.1 excels at handling highly complex problems.

Now, users can freely choose to deploy the Sonnet4.5, Haiku4.5, or Opus4.1 models on the Microsoft Foundry platform. For detailed information, please refer to the official documentation and quickly experience the AI innovation brought by Claude.
