OpenAI has announced plans to end its partnership with Cursor following the AI coding company’s acquisition by SpaceX.
Two weeks ago, Elon Musk’s company, SpaceX officially completed a $60 billion acquisition of the AI coding tool Cursor on August 14, 2026.
In a statement published on August 28, OpenAI said Cursor’s direct access to its models is proposed to end on November 12, 2026. The company said the decision was difficult, especially because many developers rely on OpenAI models through Cursor.

OpenAI said its main concern is whether SpaceX would follow its terms of service. The company pointed to its past experience with Elon Musk’s companies, including alleged contract violations involving Twitter, now part of SpaceX, and xAI’s violation of OpenAI’s terms of service. OpenAI said this made it difficult to confidently continue the partnership.
The decision is also connected to Astra, OpenAI’s upcoming model. OpenAI said the growing capabilities of future models require greater accountability and confidence that they will be used according to its rules. OpenAI has previously said Astra could have advanced agentic coding and cybersecurity capabilities, and it is strengthening safeguards around the model.
For Developers, The Big Question Now Is: What Happens Next?
Many people rely on OpenAI’s models through Cursor, and this decision could force them to rethink the tools they use. OpenAI says it understands the impact and is ready to go “above and beyond†to support developers during the transition. But with the November 12 deadline approaching, the bigger question is whether developers will stay with OpenAI’s ecosystem or begin looking for other alternatives.
