Microsoft was once the exclusive provider of data center infrastructure for OpenAI to train and run its AI models. No longer. Coinciding with the announcement of Stargate, OpenAIs massive new AI infrastructure deal with SoftBank, Oracle, and others, Microsoft says it has signed a new agreement with OpenAI that gives it right of first refusal on new OpenAI cloud computing capacity. That means that, going forward, Microsoft gets first choice over whether to host OpenAIs AI workloads in the cloud but if Microsoft cant meet its needs, OpenAI can go to a rival cloud provider.OpenAI recently made a new, large Azure commitment that will continue to support all OpenAI products as well as training, Microsoft said in a blog post. To further support OpenAI, Microsoft has approved OpenAIs ability to build additional capacity, primarily for research and training of models.OpenAI hasblameda lack of available compute for delaying its products, and compute capacity has reportedly become a source oftensionbetween the AI company and Microsoft, its close collaborator and major investor. In June, Microsoft, under shareholder pressure, permitted OpenAI to ink a deal with Oracle for additional capacity.In the blost post, Microsoft reiterated that key elements of its longstanding partnership with OpenAI remain in place through 2030, including its access to OpenAIs IP, revenue sharing arrangements, and exclusivity on OpenAIs APIs.That assumes, of course, that OpenAI doesnt achieve artificial general intelligence (AGI) under the two companiesagreed-upon definitionbefore then. When OpenAI develops AI systems that can generate at least $100 billion in profits, Microsoft will lose access to the companys technology, according to a reported agreement between the firms.OpenAI is said to be considering nullifying the agreement in a possible bid to secure more Microsoft funding.The OpenAI API is exclusive to Azure, runs on Azure and is also available through the Azure OpenAI Service, the blog post reads. This agreement means customers benefit from having access to leading models on Microsoft platforms and direct from OpenAI.Weve reached out to OpenAI and Microsoft for more information and will update this post if we hear back.
