Launch Composer 2.5

What changed

Composer 2.5 launched on May 18, 2026. It delivers better intelligence and behavior than Composer 2, with stronger performance on long-running tasks and more reliable handling of complex instructions.

Pricing shifted to Standard mode at $0.50 per million input tokens and $2.50 per million output tokens. Fast mode, set as default, runs at $3.00 input and $15.00 output per million tokens. Double usage limits apply automatically for the first week.

Why it matters

The update focuses on sustained agent work rather than quick single-turn responses. This change supports builders who want agents to carry projects across multiple steps without frequent resets or re-prompting.

Solo operators gain a practical edge on tasks that span hours instead of minutes. The pricing structure favors selective use of Fast mode for high-value work while keeping Standard available for routine steps. Cursor is betting that improved instruction following will reduce the need for constant oversight in cloud agents.

How to use it

Open Cursor and select Composer 2.5 from the model menu. Review exact rates and limits in the model docs at cursor.com/docs/models/cursor-composer-2-5. The doubled usage window starts on the day you first access the model after May 18.

Switch modes per session based on task length and budget. Full details appear in the announcement post at cursor.com/blog/composer-2-5.

Watch for

Track whether long tasks finish with fewer manual interventions over the coming weeks. Quality drops on nuanced edge cases would undermine the reliability claim. The next logical step is tighter integration between Composer and the new multi-repo environment tools released earlier in May.
