OpenAI says it intends to end the contract supplying its models to Cursor following Cursor’s acquisition by SpaceX, proposing 12 November 2026 as the cutoff. OpenAI also says future models will not be supplied through that integration. OpenAI announcement — 28 August 2026
- What changed: Developers relying on OpenAI models through Cursor now face a concrete migration deadline.
- Why it matters: Coding-agent availability depends on commercial integrations as well as technical capability.
- Practical takeaway: Keep repository instructions, specifications and test workflows provider-neutral so projects can move between Copilot, Codex, Kiro or another coding agent.
- Analysis: Teams should inventory any workflow that specifically depends on Cursor’s OpenAI models; the final product behavior after the cutoff has not yet been detailed.
