Cursor 2.0 adds coding model, UI for parallel agents

Anysphere has introduced Cursor 2.0, an update to the AI coding assistant that features the tool’s first coding model, called Composer, and an interface for working with many agents in parallel.

Both Cursor 2.0 and Composer were introduced October 29 by the Cursor team at Anysphere. Cursor is a fork of Microsoft’s popular Visual Studio Code editor, downloadable at cursor.com for Windows, MacOS, and Linux.

Composer is a frontier model that is four times faster than similarly intelligent agent models, the Cursor team said. Built for low-latency agentic coding in Cursor, Composer completes most turns in fewer than 30 seconds, according to the team’s own benchmarks. A mixture-of-experts language model that supports long-context generation and understanding, Composer is specialized for software engineering through reinforcement learning in a diverse range of development environments, the Cursor team said. The model was trained with a set of tools including codebase-wide semantic search, which makes it better at understanding and working in large code bases, they added.

Cursor’s new multi-agent interface, meanwhile, was designed to be centered around agents rather than files, the Cursor team said. Cursor 2.0 makes it easy to run many agents in parallel without them interfering with each other, powered by git worktrees or remote machines. The team said it has found that having multiple models attempt the same problem and picking the best result significantly improves the final output, particularly for harder tasks.

Cursor 2.0 also is intended to streamline the “bottlenecks” of reviewing code and testing changes when working with agents, making it easier to quickly review changes an agent has made and to dive deeper into code when needed. The addition of a native browser tool allows Cursor to test its work and iterate until the correct final result has been produced.
