Cursor Trains Custom Model Using xAI Compute
Cursor is training its own Opus-class model from scratch to replace fine-tuned open-source versions like Kimi K2. The project leverages 10-20X more compute via xAI and the Colossus 2 cluster. This shift toward model independence aims to surpass Anthropic's coding capabilities. Developers should expect a significant jump in native tool performance.
