On Aug 28 OpenAI notified SpaceX it will wind down the contract providing OpenAI models to Cursor, with a proposed shutoff of November 12, 2026; future models including the upcoming Astra will not be provided to Cursor. OpenAI says it 'cannot be confident that SpaceX will use our technology within our terms of service', citing contract violations by Musk's companies, and Anthropic publicly responded that Cursor remains a trusted partner. The announcement drew a 500-point Hacker News thread and Bloomberg coverage the next day.
