Cursor Admits Using Kimi Base For Composer 2
Cursor acknowledged over the weekend that its new coding model Composer 2 was initially built on Kimi K2.5, an open-source model from Chinese startup Moonshot AI, after an X user flagged code references. The company said it fine-tuned and reinforced the base and is complying with licensing; Moonshot confirmed an authorized commercial partnership. Cursor priced Composer 2 at $0.50 per million input and $2.50 per million output tokens, markedly below rivals.
Scoring Rationale
Official company confirmation and competitive pricing increase impact; limited novelty and primarily company-specific, not industry-changing.
