Claude Sonnet 4.5, Haiku 4.5, and Opus 4.1 Now Available in Microsoft Foundry and Microsoft 365 Copilot
Anthropic and Microsoft are expanding their partnership to make Claude Sonnet 4.5, Haiku 4.5, and Opus 4.1 available in public preview on Microsoft Foundry, enabling Azure customers to build production applications and enterprise agents using existing Azure agreements and billing.
