SAN FRANCISCO — OpenAI plans to end access to its AI models for Cursor, a coding platform acquired by Elon Musk's SpaceX, escalating an increasingly public dispute between Musk and OpenAI CEO Sam Altman.
OpenAI said it intends to stop providing its models to Cursor on November 12. The dispute follows SpaceX's acquisition of Anysphere, the company behind Cursor, in a transaction reportedly valued at approximately $60 billion.
AI Competition Is Becoming a Corporate Power Struggle
The disagreement demonstrates how quickly competition is changing in the AI industry.
Coding assistants have become one of the most commercially important applications for generative AI.
Cursor has developed a large user base among software developers who use AI systems to write, modify and analyze code.
SpaceX's acquisition gives Musk a significant position in the AI software market.
OpenAI has now decided that continuing to supply its models to the Musk-controlled company is not acceptable under its interpretation of existing agreements.
Anthropic has increased its support for Cursor, potentially giving the platform another major AI provider.
The development illustrates the increasing importance of access to foundation models.
Companies building AI applications can become dependent on the largest model providers.
If access is withdrawn, those companies may have to rapidly switch providers.
The dispute is also another chapter in Musk's long-running conflict with OpenAI.
Musk has previously accused OpenAI of abandoning its original nonprofit mission.
OpenAI has rejected those claims.
The latest confrontation is more directly commercial.
It concerns who controls access to the technology powering the next generation of software-development tools.
For Silicon Valley, the dispute demonstrates how AI competition is evolving from a race between models into a battle over entire technology ecosystems.
