OpenAI to cut Cursor's access, citing trust concerns after SpaceXAI acquisition

OpenAI will cut Cursor's access to its AI models by November 12, 2026, after SpaceXAI bought Cursor for $60B. OpenAI said Elon Musk admitted copying OpenAI's outputs to train his own models, making trust impossible. The company also mentioned its upcoming Astra model and "a new level of accountability," hinting partners may soon face broader rules beyond just following technical terms.
