The developers of the AI coding editor Cursor have announced a new version that can be used to work with multiple agents and includes its first coding model.

Cursor is an AI-powered code editor built on top of Visual Studio Code. It uses large language models to help developers write, debug, and understand code. The LLMs are used to manipulate text with autocomplete and chat query functions.

Developers can use natural language instructions to tell Cursor to create code, or can provide prompts to generate or update code. Cursor can also index the codebase, after which it can be queried in natural language. 

The Cursor team says that as agents are used more for coding, they've seen two new bottlenecks emerge: reviewing code and testing the changes. Cursor 2.0 is designed to overcome these bottlenecks by making it easier to quickly review the changes an agent has made and dive deeper into the code when you need to.

The improvements to Cursor 2 start with the addition of Composer. The developers describe this as a frontier model that is four times faster than similarly intelligent models. Composer is built for low-latency agentic coding in Cursor, completing most turns in under 30 seconds. Composer was trained with a set of tools including codebase-wide semantic search, making it much better at understanding and working in large codebases.

The other main addition is a new interface that is more focused and designed from the ground up to be centered around agents rather than files. The Cursor team says this means you can focus on the outcomes you want while agents take care of the details. When you need to dive deep into the code, you can still easily open files in the new layout or switch back to the classic IDE.

Cursor 2.0 makes it easy to run many agents in parallel without them interfering with one another, powered by git worktrees or remote machines. The developers say they've even found that having multiple models attempt the same problem and picking the best result significantly improves the final output, especially for harder tasks.

Finally, the new version also has a native browser tool that allows Cursor to test its work and iterate until it has produced the correct final result.

Cursor 2 is available now.
