Claude in Microsoft Foundry is now generally available
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.
“At NVIDIA, we use autonomous AI agents every day to help our teams move faster and think bigger. Claude models bring strong reasoning, coding and enterprise capabilities that are valuable for complex technical work. With Claude now available in Microsoft Foundry running on NVIDIA GB300 GPUs, more organizations can run advanced, specialized AI agents with the performance, scale and security needed for production.”
“Running Claude models on Azure has given us the sustained throughput and reliability our enterprise customers expect. The combination of frontier model quality and enterprise-grade infrastructure is what makes Bolt viable for the Fortune 500.”
“Between Anthropic and Azure, we get the best capabilities in the world and we get the best security in the world. And that's exactly what nuclear needs. It's how we compressed a safety analysis that would have taken 200 human days into a single day.”
“Our customers describe their tests in plain English, and Momentic runs through the interface to verify everything works before a release ships. We found Claude Opus especially suited to this, and running it on Azure Foundry we now serve millions of tokens per minute with the reliability our customers depend on.”
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.
