What is Composer
Composer isCursor's self-developed coding model, designed for low-latency agentic coding. The model generates extremely fast, reaching up to 250 tokens per second, 4 times that of models with equivalent intelligence, and completes most tasks within 30 seconds. Composer is trained with tools such as semantic search, giving it significantly stronger understanding and handling of large codebases. The model supports calling a variety of tools, such as code editing, terminal commands, and semantic search, and also has parallel processing capabilities, able to run multiple agents in parallel to improve the efficiency of solving complex tasks. Composer is optimized through reinforcement learning, can handle tasks efficiently and reduce ineffective output, and is now integrated inCursor 2.0.
Composer's main features
-
Fast generation and low-latency interaction: Generation speed is 4 times that of models with equivalent intelligence, reaching up to 250 tokens per second, and most tasks are completed within 30 seconds, supporting low-latency agentic coding.
-
Efficiently handling large codebases: Trained with tools such as semantic search, it has significantly stronger understanding and handling of large codebases.
-
Multi-tool calling and parallel processing: Supports calling production-grade search and editing tools to solve various difficult problems, and also supports running multiple agents in parallel without interfering with each other, improving the efficiency of solving complex tasks.
-
Reinforcement learning optimization and self-learning capability: Optimizes the model through reinforcement learning, encouraging efficient tool use and parallel processing, and spontaneously acquires capabilities such as complex search, bug fixing, and writing unit tests during training.
How to use Composer
-
Install Cursor: Visit the Cursor official website to download the installation package, or directly downloadCursor APPand follow the prompts to complete the installation.
-
Start a task: Enter your coding requirements in the interface, and Composer responds quickly within 30 seconds.
-
Handle large codebases: Use Composer's semantic search feature to quickly locate and handle problems in large codebases.
-
Run multiple agents in parallel: Start multiple agents simultaneously in the interface, assign different tasks, and choose the best result.
-
Code review and change testing: Use Composer's quick review feature to view changes, switch to the classic IDE interface when necessary to dig deeper into the code, and continuously iterate and test through the native browser tool.
