Cursor Composer 2.0 and Kimi 2.5: a controversial hypothesis

A user discovered that Cursor Composer 2.0, when used, sends requests to /chat/completions containing the string accounts/anysphere/models/kimi-k2p5-rl-0317-s515-fast. This led to speculation that the service might be based on the Kimi 2.5 model.

Elon Musk contributed to fueling the discussion, commenting on the news and joking about the alleged dependence on Kimi 2.5.

The Kimi 2.5 license, a modified version of the MIT license, would require Cursor to explicitly state the use of the model.

For those evaluating on-premise deployments, there are trade-offs to consider carefully. AI-RADAR offers analytical frameworks on /llm-onpremise to evaluate these aspects.
