Microsoft Corp. -- OpenAI's largest investor and previously its exclusive cloud-computing provider -- recently announced a new commitment from OpenAI to spend some $250 billion on its Azure cloud unit. Oracle Corp. has inked a $300 billion deal to provide OpenAI with data centers, and earlier this year OpenAI disclosed that Alphabet Inc.'s Google Cloud Platform was among the companies powering ChatGPT. The startup also has a $22.4 billion deal with CoreWeave Inc., a leader among a new crop of so-called neo clouds pitching their services to AI developers.
