OpenAI cuts Cursor's model access, citing distillation concerns and Astra-era accountability

OpenAI will end Cursor's model access by November 12, 2026, after its $60B acquisition by SpaceXAI. OpenAI pointed to Elon Musk's admitted distillation — training new AI models on a competitor's outputs — as proof it cannot trust SpaceXAI to honor service terms. OpenAI also invoked its upcoming Astra model and "a new level of accountability," suggesting future partners face alignment requirements beyond technical compliance.
