Starting today, Claude models are generally available in Microsoft Foundry, hosted on Azure. Claude runs in your Azure environment with the authentication, billing, and governance controls your teams already use. You can choose where inference is processed, including a US data zone for teams with data residency requirements. Anthropic operates the inference and is the data processor.
Build with Claude through your Azure account
To start, Claude Opus 4.8 and Claude Haiku 4.5 are available in the Messages API, with core capabilities like prompt caching and extended thinking to support use cases ranging from coding and agentic work to complex reasoning. We'll continue expanding what's available in Foundry over time.
Claude in Microsoft Foundry is Azure-native, working with your existing Azure identity, networking, and governance controls. You receive a single consolidated invoice, and for eligible customers with a Microsoft Enterprise Agreement, Claude usage draws down a Microsoft Azure commitment.
Run Claude in Azure, operated by Anthropic
There are two ways to run Claude in Microsoft Foundry. Choose hosted on Azure** **when running in your Azure environment matters, with Azure authentication, billing, governance, and a US data zone. Choose hosted on Anthropic (previously the Foundry Preview) when you need the full set of API features or a model that is not yet available on Azure. Over time, we aim to have feature and model parity between the hosted on Azure offering and the Anthropic-hosted one.
