OpenAI plans to block Cursor users in three months, sparking debate over API proxying
AccBalanced · x · 2026-08-31
OpenAI announced plans to block Cursor users from accessing its models within three months. Cursor responded that OpenAI models serve only about 5% of their traffic and they are working with the OpenAI team to resolve the issue, emphasizing their long-standing trust in OpenAI as neutral infrastructure.
The move has sparked debate. Critics question why providers allowed Cursor to proxy access from day one, arguing it leaks user data to two companies instead of one. Others suggest that while monopolies are bad, the solution is more companies building LLMs, and Cursor's incentive to make alternatives like Composer or Grok competitive benefits consumers.
