Anthropic's Claude AI models are now publicly available inside Microsoft Foundry, Microsoft's platform for building and deploying AI applications.
According to Insider Monkey, the models are hosted on Microsoft Azure and run on Nvidia GB300 Blackwell Ultra GPUs, the graphics processors that power much of today's most demanding AI work. Insider Monkey reports that the update was shared on June 29, when the company said the Claude models running in this setup had become publicly available.
The arrangement ties together three of the biggest names in artificial intelligence. Anthropic supplies the Claude models, Microsoft provides the cloud infrastructure and the Foundry platform where developers access them, and Nvidia supplies the underlying Blackwell Ultra chips that do the heavy computing. Yahoo Finance and other outlets carried the same news about Claude models running on Blackwell Ultra hardware.
For a general reader, the practical takeaway is straightforward: businesses that already build software on Microsoft's Azure cloud can now tap Anthropic's Claude models directly, without stitching together a separate arrangement with Anthropic.
The move is notable because Microsoft has been closely associated with OpenAI, the maker of ChatGPT. Offering a rival's models inside its own developer platform signals that major cloud providers increasingly want to give customers a menu of AI options rather than a single choice.
Why it matters: making Claude available on Microsoft's cloud, powered by Nvidia's latest chips, lowers the barrier for companies to experiment with competing AI models and underscores how tightly the industry's leading players now depend on one another.
