Users of the Cursor IDE are expressing frustration with the platform's Bring Your Own Key (BYOK) support, claiming it is deliberately crippled. The issue arises when users enable an external API key (e.g., from OpenAI or Anthropic) and then attempt to use Cursor's proprietary models like Composer 2.5. Instead of routing requests appropriately, Cursor's system reportedly blocks the use of Composer, citing that it does not support custom API keys. This behavior, which Cursor has shifted from being described as a bug to an intentional design choice, prevents users from seamlessly integrating their own API keys with Cursor's models, leading to accusations that the company is creating friction to encourage use of its own billing and models.
