Composer 2
Cursor's second-generation in-house coding model, now the default agent model in the editor, with faster multi-file edits and native terminal tool use.
Overview
Anysphere shipped Composer 2 for Cursor on October 8, 2026, trained specifically on large multi-file refactor and agentic-edit trajectories rather than as a general chat model. Cursor says Composer 2 runs at roughly 2x the token throughput of Composer 1 at similar edit-quality scores on its internal evaluation set, and builds terminal and test-runner tool use directly into the base model rather than through a separate harness prompt. It is now the default model for Cursor's Agent and Background Agent modes.
