Cursor Ships Composer 2.5 With Major Intelligence Upgrade
Cursor's Composer 2.5 promises better handling of long-running tasks and complex instructions, built on Kimi K2.5.
Cursor just dropped Composer 2.5, and the company is calling it a substantial leap over its predecessor. The update targets two persistent pain points: sustaining performance on long-running tasks and reliably following complex instructions.
Under the hood, Composer 2.5 is built on Kimi K2.5. Cursor says the result is a meaningful improvement in both intelligence and behavior compared to Composer 2.
No incremental polish here. The jump from version 2 to 2.5 is framed as a significant upgrade rather than a minor iteration. The focus on sustained work suggests Cursor is going after workflows where previous versions would lose coherence or drift off-task midway through longer operations.
Details beyond the core claims remain thin. But for developers already embedded in Cursor's ecosystem, the update is live and available now.
