OpenAI brings its models to Amazon's cloud after ending exclusivity with Microsoft

openai's models are now available on amazon web services, ending years of exclusivity with microsoft. aws customers can test openai's models and its codex agent through amazon bedrock, with general availability coming in the next few weeks. "this is what our customers have been asking us for for a really long time," aws ceo matt garman said at a launch event in san francisco. the shift follows monday's renegotiation of openai's microsoft deal, which lets the ai company cap revenue share payments and serve customers on any cloud. openai revenue chief denise dresser told employees in a memo that the old arrangement "has also limited our ability to meet enterprises where they are — for many that's bedrock." openai ceo sam altman sent a recorded message from court in oakland, where he's fighting elon musk's lawsuit. the partnership has been building for months. in november, openai announced a $38 billion commitment with aws, and in february, amazon said it would invest $50 billion in altman's company. openai will use two gigawatts of aws' custom trainium chips for training. the announcement came after the wall street journal reported openai missed internal user and revenue goals, which altman and cfo sarah friar called "ridiculous."
