On August 29, 2026, OpenAI announced on X that it was terminating its partnership with Cursor due to Cursor's acquisition by SpaceX. OpenAI stated that, according to its proposal, direct access to OpenAI models in Cursor would end on November 12.
In the announcement, OpenAI acknowledged that the decision would most affect developers who rely on OpenAI models in Cursor, and promised to 'do everything in its power' to support them, but did not provide specific measures.
OpenAI's announcement sparked strong reactions on X, with 9.6 million views. User Annalea L questioned the decision, noting that OpenAI had previously claimed it would not restrict users' choice of tools, and argued that this move broke that promise.
Another user, Felix, posted a brief summary that was widely shared, indicating the developer community's broad attention to the news.
Replit CEO Amjad Masad responded on X, saying developers can use OpenAI models for free on Replit, and emphasized that its router makes high-end models more cost-effective.
