In its latest update, the developer editor Cursor AI integrates advanced functions for AI-supported programming that can fundamentally improve the software development process.
The latest update of the Visual Studio Code-based AI editor Cursor brings significant new features for developers. The focus is on the new Fusion Tab model, which supports multi-file editing and syntax highlighting. This enhancement enables developers to perform cross-file refactorings and navigate complex code bases more efficiently. The technology uses a mixture of local CodeLlama variants for small changes and Claude 3.5 Sonnet for more complex tasks.
Also new is the Background Agent in the preview version, which enables AI agents to be executed in parallel and remotely. This function automates routine tasks such as linting, testing and documentation creation, allowing developers to focus on more creative aspects of their work. According to initial user experience, the background agent reduces context switching by up to 40% for standardized tasks.
With the @folders function, Cursor addresses one of the main problems in AI-supported programming: limited context. This feature makes it possible to include entire directories in the context, whereby large files are automatically summarized. A BERT-based algorithm extracts the most important classes and methods while omitting implementation details. Tests show an impressive accuracy of 98% when answering queries on large code bases.
Technically, Cursor uses a multi-level AI model system that balances cost and performance. A proprietary cursor-small model is used for inline predictions, while Claude 3.7 Sonnet is used for cross-file processing. The background agent uses GPT-4 Turbo. This architecture enables real-time suggestions while reserving more powerful models for more complex tasks.

The most important facts about the update:
- The new Fusion Tab model supports multi-file processing and syntax highlighting with response times under 200ms
- The background agent allows parallel execution of AI assistants on remote servers for tasks such as testing and documentation
- The @folders function allows entire directories to be integrated into the context with intelligent summarization of large files
- Cursor uses a three-tier model system for different levels of complexity of code analysis and generation
- Compared to competitors like GitHub Copilot, Cursor offers superior project-wide context analysis and deeper IDE integration
