Elon Musk is attempting to block OpenAI's transition to a for-profit model, citing a breach of their founding agreement. In response, OpenAI released email exchanges with Musk, highlighting his previous support for a for-profit structure. OpenAI argues Musk's claims contradict his past actions and intentions. Despite Musk's legal challenges, including an antitrust case, OpenAI is determined to pursue its new business direction under CEO Sam Altman.
