OpenAI breaks free of Microsoft cloud

OpenAI and Microsoft rewrote their partnership on April 27, ending Microsoft’s exclusive rights to sell OpenAI models and letting OpenAI offer products on rival clouds. (openai.com) (blogs.microsoft.com) Microsoft said it remains OpenAI’s primary cloud partner, and OpenAI products will still ship first on Azure unless Microsoft cannot or chooses not to provide the needed capacity. (blogs.microsoft.com) (cnbc.com) The amended deal also changed the money flow. Microsoft’s license to OpenAI intellectual property now runs through 2032 on a non-exclusive basis, and Microsoft will no longer pay OpenAI a revenue share. (blogs.microsoft.com) (forbes.com) Amazon moved within a day. On April 28, Amazon Web Services said OpenAI models were becoming available through Bedrock, its service for using outside AI models inside Amazon’s cloud. (cnbc.com) (geekwire.com) Amazon said Bedrock customers can use GPT-4.1, GPT-4.1 mini and GPT-4.1 nano, and it described the move as a “major expansion” of its partnership with OpenAI. (cnbc.com) (usnews.com) For customers, the change is about where OpenAI software can run. A company that already keeps data and applications on Amazon Web Services or Google Cloud no longer has to route every OpenAI deployment through Microsoft Azure. (axios.com) (venturebeat.com) That matters for procurement as much as engineering. Cloud buyers often negotiate on price, data residency and resilience, and a multi-cloud OpenAI can now pitch enterprises that were reluctant to standardize on Azure. (axios.com) (nbcnews.com) The shift also reflects how OpenAI’s infrastructure has already spread beyond Microsoft. OpenAI has separately built out Stargate with Oracle, SoftBank and CoreWeave to secure more data center capacity for training and serving models. (openai.com) (cnbc.com) Microsoft is not out of the picture. It still holds a large equity stake after investing more than $13 billion since 2019, and Azure keeps first-call status for OpenAI product launches when it can meet demand. (cnbc.com) (latimes.com) The practical result is simpler than the contract language: OpenAI is no longer tied to one cloud, and Amazon was first to turn that new freedom into a product listing.
