Ah。 Big spender Microsoft considering suing OpenAI? Microsoft previously invested over $13 billion in OpenAI for ChatGPT and obtained exclusive deployment and API call rights for its model on its own cloud service Azure. However, after completing a new round of financing, OpenAI went to reach a cooperation agreement with Amazon worth approximately $50 billion. Both parties have proposed a new architecture that can technically attempt to bypass the traditional API path and directly integrate OpenAI from Amazon AWS instead of Microsoft. Microsoft is currently evaluating whether to take legal action.
