Cursor

What is Cursor

Cursor is an AI code editor launched by AnysphereAI code editor, based on GPT3.5 and GPT4.0 models, supports multiple languages such as Python, Java, C#, and JavaScript, and uses keyboard shortcuts to enable features such as automatic code generation, editing, and discussion, significantly improving development efficiency. Cursor has advanced features such as code refactoring, understanding, and optimization. Cursor has launched web and mobile Agents. It enables seamless use of AI programming agents on any device. Multiple Agent tasks can run in parallel. It provides 200 uses of GPT3.5 and 50 uses of GPT4.0 per month, meeting the needs of most users.

The fully upgraded Cursor 2.0, equipped with the self-developed coding model Composer, can complete complex tasks within 30 seconds, with a code generation speed of 250 tokens/second, 400% faster than peers. Cursor 2.0 supports features such as voice-generated code, native browser tools for testing code, and multiple Agents running simultaneously, and its interface has changed from "file-centric" to "Agent-centric." Composer is trained based on reinforcement learning and MoE architecture, runs directly in real environments, and has strong reasoning and generalization capabilities.

Cursor 2.2 introduces debug mode, which can insert logs while the application is running, helping developers quickly locate and fix complex bugs. Planning mode has also been improved, adding inline flowcharts and task assignment features to make team collaboration more efficient. The multi-agent "judge" mechanism can automatically evaluate the results of multiple agents, recommend the best solution, and include detailed comments, saving the trouble of filtering results.
