Cursor Composer 2 appears to be built on Kimi K2.5 as the base model! 🤫 The Kimi model was then post-trained further with reinforcement learning for coding performance. I think it's quite likely true, as Cursor wouldn't train a completely new foundation model.












@mitsuhiko I found gpt 5.4 pretty good at cleaning up stuff from earlier models needs some meta prompting in some cases that help me understand what status quo is and what our options are etc but I expect this to continue w/ better models

We’re introducing GPT-5.4 mini and nano, our most capable small models yet. GPT-5.4 mini is more than 2x faster than GPT-5 mini. Optimized for coding, computer use, multimodal understanding, and subagents. For lighter-weight tasks, GPT-5.4 nano is our smallest and cheapest version of GPT-5.4. openai.com/index/introduc…
