OpenAI said it’s ending its contract with Cursor, a coding startup recently acquired by SpaceX, because it doesn’t trust an Elon Musk-owned company to comply with its terms of service.

The company said in a statement published on Friday night that it plans to shut off Cursor’s access to OpenAI models on November 12.

OpenAI did not accuse Cursor of violating any terms. It instead pointed to past conduct by another Musk-owned company, Twitter, which Musk bought in 2022 and merged with SpaceX earlier in February.
