According to CoinMeta, OpenAI announced the end of a nearly four-year partnership with Cursor. Subsequent new models will no longer be integrated with Cursor, and the direct supply of existing models is scheduled to cease on November 12, 2026. The contract between the two parties allows OpenAI to terminate the agreement after Cursor is acquired. OpenAI accuses Musk of violating their contract after acquiring Twitter and states that SpaceX is not trustworthy and should not be entrusted with new models.
