Cursor releases Composer 2.5, a powerful AI coding model. It's built on Kimi K2.5 with enhanced training.
Cursor has introduced Composer 2.5, a significant upgrade to its AI coding model, built on the Kimi K2.5 foundation. By training on 25 times more synthetic tasks than its predecessor, Composer 2.5 matches the benchmarks set by industry heavyweights Opus 4.7 and GPT-5.5, but at a lower cost. This development is crucial as it democratizes access to advanced AI coding capabilities, making it more affordable for developers and businesses.
As we reported on May 17, Claude Code is the engine behind Cursor, and this update further enhances its capabilities. Composer 2.5 is designed to handle long-running tasks, make subtler tool choices, and adhere to complex instructions more reliably. For the next week, Cursor is doubling the included usage of the model, allowing users to experience its full potential.
What to watch next is how Composer 2.5 will impact the AI coding landscape, particularly in comparison to established models like Opus 4.7 and GPT-5.5. With its competitive pricing and enhanced capabilities, Composer 2.5 is poised to be a game-changer in the industry, and its adoption will be closely monitored by developers, businesses, and investors alike.
