title: "Introducing Cursor 2.0 and Composer"
description: "Cursor 2.0 introduces Composer, described as the product’s first coding model, alongside an interface designed for running multiple agents in parallel. Composer is built for low-latency agentic coding, completes most turns in under 30 seconds, and was trained with tools including codebase-wide semantic search to improve work in large codebases. The new interface centers on agents and outcomes rather than files, while still allowing users to open files in a redesigned layout or return to the classic IDE; parallel runs are isolated through git worktrees or remote machines. The release also targets review and testing bottlenecks by simplifying change inspection and adding a native browser tool that lets Cursor test its work and iterate, and Cursor 2.0 is now available."

# Introducing Cursor 2.0 and Composer

**Type:** Announcement

## Summary

Cursor 2.0 introduces Composer, described as the product’s first coding model, alongside an interface designed for running multiple agents in parallel. Composer is built for low-latency agentic coding, completes most turns in under 30 seconds, and was trained with tools including codebase-wide semantic search to improve work in large codebases. The new interface centers on agents and outcomes rather than files, while still allowing users to open files in a redesigned layout or return to the classic IDE; parallel runs are isolated through git worktrees or remote machines. The release also targets review and testing bottlenecks by simplifying change inspection and adding a native browser tool that lets Cursor test its work and iterate, and Cursor 2.0 is now available.

## Context

As coding agents are used more, code review and testing changes have emerged as bottlenecks. The release also addresses the need to run multiple agents without interference and to work effectively with large codebases.

## Approach / What changed

The release combines Composer, a coding model trained with tools including codebase-wide semantic search, with an agent-centered interface. It supports parallel agents through git worktrees or remote machines, simplifies review, and adds a native browser tool for testing and iteration.

## Takeaways

- Composer is described as four times faster than similarly intelligent models, with most turns completing in under 30 seconds.
- Cursor 2.0 can run many agents in parallel without interference by using git worktrees or remote machines; trying multiple models on one problem can improve final output, especially for harder tasks.
- A native browser tool allows Cursor to test its work and iterate, while the interface makes it easier to review agent-made changes and inspect code.
