Sam Altman Ends OpenAI Partnership with Cursor Amid Feud with Elon Musk

OpenAI has decided to end its partnership with Cursor, the AI coding tool developed by Anysphere and now owned by SpaceX. The cutoff is set for November 12, as OpenAI cited a lack of trust in Elon Musk's companies adhering to their terms due to past contract disputes. This decision follows years of legal battles between Musk and former colleagues from his time at OpenAI, including Sam Altman. Despite the loss, SpaceX appears unfazed given that only about 5% of Cursor’s traffic relies on OpenAI models. The company has other AI partners like Anthropic, which is eager to expand its collaboration with SpaceX after Anysphere's acquisition for $60 billion. Meanwhile, Musk dismissed the decision as unimportant and reiterated his claim against Altman in a recent social media post. The feud dates back years when Musk co-founded OpenAI before leaving the board in 2018. He later launched xAI and sued OpenAI over its alleged shift from nonprofit to profit-driven goals, though he lost that case earlier this year.
