FuXi

FuXi is an AI coding agent that runs in the terminal to edit code, execute commands, and manage tools with multi-provider model routing.

FuXi is an AI terminal development platform designed for individuals and teams to build and create without requiring coding skills. It operates directly in the terminal as a self-contained binary with no runtime dependencies. The platform supports over 30 AI model families, including Anthropic, OpenAI, Gemini, DeepSeek, GLM, Kimi, Qwen, and Grok. It features complexity-based tiered routing, automatic failover, and primary-backup model racing. Users can connect any MCP server, use 50+ built-in tools for file edits and diagnostics, and extend functionality via hot-reloaded hooks, skills, and plugins.
