Introducing Cursor 2.0 and Composer
Oct 29, 2025Cursor

Summary
Introduced Composer, a frontier AI model optimized for low-latency agentic coding, completing most turns in under 30 seconds. This model was trained with tools like codebase-wide semantic search for better understanding of large codebases. Also introduced a new multi-agent interface centered around agents rather than files, enabling parallel execution of multiple agents powered by git worktrees or remote machines. Developed native browser tools for testing agent work and iterating until correct results are produced, addressing bottlenecks in code review and testing.
