# Cursor 2.0: Composer, Multi-Agent UI, Terminal

> Cursor 2.0 launches Composer (fast agentic coding), parallel multi-agent workflows, GA browser testing, improved reviews, and sandboxed terminals.

## Introduction

Cursor announced a major release with **Cursor 2.0**, introducing its first coding model **Composer** and a redesigned, **multi-agent** interface. The update focuses on faster agentic coding loops, parallel execution without file conflicts, improved review/testing workflows, and enterprise-grade safety with sandboxed terminals ([blog](https://cursor.com/blog/2-0), [changelog](https://cursor.com/changelog/2-0)).

## What’s new in Cursor 2.0

### Composer: fast agentic coding model
- Frontier coding model built for low-latency agent workflows
- Reported to be ~4x faster vs similarly capable models, with most turns <30s
- Trained to leverage codebase-wide semantic search for large projects

### Multi-agents in parallel
- Run up to eight agents in parallel on a single prompt
- Isolation via git worktrees or remote machines to prevent file conflicts
- Sidebar manages agents and plans in the new editor UI

### Browser for Agent (GA)
- In-editor browser tooling with element selection and DOM forwarding to agents
- Enterprise support expanded in 2.0

### Sandboxed terminals (GA on macOS)
- Default sandbox execution for agent commands with workspace read/write and no internet by default
- Admin controls for enterprise to enforce sandbox, git, and network access policies

### Improved code review experience
- Easier, consolidated diff review across multiple files without jumping between them

### Team commands and rules
- Define team-level custom commands and rules in the dashboard; centrally managed and auto-applied to teammates

### Voice mode
- Control Agent with speech-to-text; configurable submit keywords

### Performance upgrades
- Faster Python and TypeScript LSPs on large projects with dynamic memory limits
- Memory leak fixes and improved overall responsiveness, especially when viewing diffs

### Plan Mode in background
- Plan with one model, build with another; optionally run plans in parallel to compare

### Prompt UI and harness improvements
- Inline file/directory pills, better copy/paste of tagged context
- Agent harness upgraded across models, with notable gains for GPT-5 Codex

### Cloud agents and enterprise features
- 99.9% reliability, instant startup for cloud agents; improved send-to-cloud flow
- Enterprise hooks distribution from web dashboard and audit logs

## Why it matters

Cursor 2.0 targets the two biggest bottlenecks emerging with agentic coding—review and testing—while accelerating iteration speed. Parallel agents, better diffs, and a native browser tool aim to shorten the loop from planning to validated changes, especially on large TypeScript/Python codebases. Sandboxed execution and enterprise controls improve safety and governance.

## Availability

Cursor 2.0 is available now. You can download it via the official site and review the full changelog for details ([blog](https://cursor.com/blog/2-0), [changelog](https://cursor.com/changelog/2-0)).
