Introducing Claude Opus 4.5 In Microsoft Foundry
Microsoft, Monday, November 24th, 2025
We're at a real inflection point in the AI landscape, a threshold where models move from useful assistants to genuine collaborators. Models that understand the objective, factor in constraints, and execute complex multi-tool workflows.
Models that not only support processes, but help restructure them for reliability, scale, and operational efficiency.
Anthropic's newest model, Claude Opus 4.5, embodies that shift. Today, we are excited to share that Opus 4.5 is now available in public preview in Microsoft Foundry, GitHub Copilot paid plans, and Microsoft Copilot Studio.
