Cursor has released its new Composer 2.5 model, which leverages Kimi as a base and incorporates significant additional training and reinforcement learning. The model reportedly achieves performance comparable to Anthropic's Claude Opus 4.7 at one-tenth the cost, making it a highly cost-effective option for developers. This move towards self-developed models is seen as a strategic necessity for Cursor, especially after Anthropic launched its own coding product, potentially positioning Cursor's unique RL training and developer workflow data as its core competitive advantage.
