OpenAI to cut Cursor off from its models on Nov 12 after SpaceX buyout

OpenAI says it will wind down the contract supplying its models to Cursor, with access ending November 12, after SpaceX closed its roughly $60 billion purchase of parent company Anysphere. OpenAI cited a change-of-control clause and doubts that Musk-owned firms will honor its terms, not any wrongdoing by Cursor. Cursor keeps Anthropic, Google and xAI models; OpenAI is about 5% of traffic.
