OpenAI terminates Cursor API access after SpaceX acquisition

OpenAI stated it will no longer supply models or endpoints to Cursor after SpaceX completed the purchase. The decision aligns with prior terminations of access for entities under new ownership that conflict with usage policies. Primary source documentation lists the change without additional rationale or transition period.

No public benchmark data or deployment logs accompany the announcement. Related OpenAI actions on acquired tools show consistent revocation within 30 days of ownership transfer in three prior cases. Cursor usage metrics from third-party reports indicated heavy reliance on OpenAI GPT-4o completions prior to the cutoff.

Operationally, Cursor users must migrate to alternative providers or self-hosted models within the stated window. This enforces separation between OpenAI infrastructure and SpaceX-controlled products. Future access requests from the same entity will route through standard enterprise review channels.

SpaceX has not issued a replacement model announcement. Affected developers report immediate fallback to Anthropic and local inference stacks in public forums.
