The announcement was made at Microsoft’s Build developer conference on Monday, and was notable given Microsoft’s partnership with OpenAI. Musk founded xAI, the startup behind Grok, but he has also been locked in a feud with OpenAI since stepping down from its board in the late 2010s, citing disagreements over its leadership direction.

“Microsoft and xAI are thrilled to unveil the availability of Grok 3 into the Azure AI Foundry Models, marking a significant milestone in AI accessibility and innovation,” said Vaidyaraman Sambasivam, the partner Head of product for Azure AI, in an announcement blog post.
