About

Composer is Cursor’s custom-built agentic AI model optimized specifically for software engineering tasks and designed to power fast, interactive coding assistance directly within the Cursor IDE, a VS Code-derived editor enhanced with intelligent automation. It is a mixture-of-experts model trained with reinforcement learning (RL) on real-world coding problems across large codebases, so it can produce high-speed, context-aware responses, from code edits and planning to answers that understand project structure, tools, and conventions, with generation speeds roughly four times faster than similar models in benchmarks. Composer is specialized for development workflows, leveraging long-context understanding, semantic search, and limited tool access (like file editing and terminal commands) so it can solve complex engineering requests with efficient and practical outputs.

About

Incbury is an independent UK AI company that develops its own small language models, known as Atom. Incbury Chat is an AI assistant for conversation, writing, research, and analysis, with web search, projects, and file handling. Incbury Code is a coding agent for desktop and terminal workflows, with sidebars for VS Code and Cursor; it can inspect codebases, propose file changes for approval, and run commands and tests. The Incbury API gives developers OpenAI-compatible access to Atom for adding language-model features to applications, including streaming and function calling. Chat offers a free plan with daily fair-use limits; API and Code use prepaid credits. Incbury publishes benchmark results and examples of model limitations. Its products serve individuals, developers, startups, and teams seeking chat, coding assistance, or AI-powered applications.
