BENGALURU:

Microsoft is considering legal action against its partner OpenAI and Amazon over a $50 billion deal that could violate its exclusive cloud agreement with the ChatGPT maker, the Financial Times reported on Wednesday.

Last month, Amazon and OpenAI signed several agreements, including one that makes Amazon Web Services the exclusive third-party cloud provider for Frontier, OpenAI's enterprise platform for building and running AI agents.

The dispute centres on whether OpenAI can offer Frontier via AWS without violating the Microsoft partnership, which requires the startup's models to be accessed through the Windows maker's Azure cloud platform, the FT report said, citing sources. OpenAI and Microsoft recently stated together that "Azure remains the exclusive cloud provider of stateless OpenAI APIs," a Microsoft spokesperson said in an emailed statement, referring to software interfaces used to access OpenAI's models.
