Claude in Microsoft Foundry is now generally available (claude.com)

Claude models are now generally available in Microsoft Foundry, enabling organizations to run these AI models directly in their Azure environment with seamless integration into existing authentication, billing, and governance workflows. This launch includes Claude Opus 4.8 and Claude Haiku 4.5, accessible via the Messages API, featuring essential functionalities like prompt caching and extended reasoning capabilities suited for various applications, including coding and complex decision-making. The significance of this development lies in its potential to enhance enterprise AI workflows by leveraging Microsoft Azure's robust infrastructure and security measures. Users can choose between two deployment options: hosted on Azure for direct integration and data residency compliance, or on Anthropic for access to the full range of API features. As the partnership evolves, there are plans to achieve feature and model parity between both deployment options, maximizing flexibility for developers. Overall, this milestone marks a crucial step in making advanced AI tools more accessible and efficient for organizational use.
