About Composer 2.5

Cursor's agentic coding model released May 18, 2026. Built on Moonshot AI's Kimi K2.5 open-source checkpoint with targeted RL using textual feedback and 25× more synthetic training tasks than Composer 2. Designed for long-horizon software engineering tasks: multi-file edits, terminal command execution, codebase-wide semantic search, and autonomous task planning. Uses Cursor's compaction-in-the-loop context management for long coding sessions. Available on all Cursor plans; accessed through the Cursor IDE (not a standalone API). Standard pricing: $0.50/M input, $2.50/M output; Fast (default): $3.00/M input, $15.00/M output.
