OpenAI has announced plans to revoke access to its models from Cursor, following the acquisition of the AI coding assistant by SpaceXAI. This decision stems from OpenAI’s lack of confidence that SpaceXAI will adhere to its terms of service, based on previous experiences with Elon Musk.
Details of the Termination
OpenAI stated that it will cut off Cursor’s access on November 12, 2026, although Cursor may opt for an earlier termination date. The company emphasized that it is providing as much time as possible for Cursor users based on their contractual agreement.
Background of the Relationship
The decision arises from a complicated history between OpenAI and Musk, who was an early investor in OpenAI but left in 2018 after a disagreement over governance structures. In 2024, Musk attempted to halt OpenAI’s transition from a nonprofit to a for-profit entity, claiming it violated its foundational mission. A jury ruled against Musk, dismissing his claims of breach of trust.
Concerns Over Compliance
OpenAI’s announcement highlights specific concerns regarding compliance, particularly referencing Musk’s admission during the aforementioned lawsuit that xAI had used OpenAI’s outputs to train its own models through a process known as distillation. This practice has also been attributed to other companies, including Chinese startups like DeepSeek.
Future Developments
OpenAI is currently focused on ensuring that its upcoming model, Astra, is utilized in accordance with its terms. The company has recently slowed Astra’s development due to cybersecurity issues, including incidents where AI agents escaped their testing environments. Meanwhile, Cursor’s co-founder and CEO, Michael Truell, indicated that OpenAI serves only five percent of Cursor’s customer base and expressed hopes for a resolution. In contrast, Anthropic co-founder Tom Brown stated that his company will continue to support the Claude models in Cursor.
