# MiMo-Code — AI Coding Agent by Xiaomi Where Models and Agents Co-Evolve

> Open-source AI coding agent from Xiaomi's MiMo team that pairs a specialized code model with an agentic CLI for iterative software development.

## Install

Save in your project root:

# MiMo-Code — AI Coding Agent by Xiaomi

## Quick Use
```bash
npm install -g @xiaomi/mimo-code
mimo-code init
mimo-code "Add input validation to the user registration endpoint"
```

## Introduction
MiMo-Code is an open-source AI coding agent developed by Xiaomi's MiMo research team. It combines a purpose-trained code generation model with an agentic loop that can read files, run commands, and iteratively refine code changes in your repository.

## What MiMo-Code Does
- Generates and edits code across multiple files in a repository
- Executes shell commands to test and validate changes in a feedback loop
- Understands project context by reading relevant source files on demand
- Supports multi-turn conversations for iterative refinement
- Co-evolves model and agent capabilities through reinforcement learning

## Architecture Overview
MiMo-Code pairs a fine-tuned language model optimized for code understanding with a tool-calling agent runtime. The agent has access to file reading, writing, and command execution tools. A reinforcement learning pipeline continuously improves the model based on real coding task outcomes, creating a feedback loop between model quality and agent effectiveness.

## Self-Hosting & Configuration
- Install the CLI via npm; the agent connects to local or remote model endpoints
- Configure model backend (local GPU, API endpoint) in the config file
- Set workspace root and file access permissions per project
- Customize tool availability (shell, file I/O, browser) through agent profiles
- Supports running behind corporate proxies with custom CA certificates

## Key Features
- Co-evolution framework jointly improves the model and agent through RL
- Multi-file editing with automatic dependency tracking across changes
- Built-in test execution validates modifications before proposing them
- Conversation history persists across sessions for long-running tasks
- Extensible tool system allows adding custom capabilities

## Comparison with Similar Tools
- **OpenHands** — broader AI dev agent with visual capabilities but no co-evolution training
- **Aider** — terminal-based pair programmer focused on git integration
- **SWE-agent** — research-focused agent for GitHub issue resolution
- **Cline** — VS Code extension with autonomous coding but IDE-dependent
- **Continue** — IDE code assistant focused on completion rather than agentic editing

## FAQ
**Q: Which programming languages does MiMo-Code support?**
A: The model is trained on Python, TypeScript, Java, Go, Rust, and C++, with best performance on Python and TypeScript.

**Q: Can I use my own model backend?**
A: Yes. MiMo-Code supports OpenAI-compatible API endpoints, so you can point it at any compatible model server.

**Q: How does the co-evolution training work?**
A: The model is periodically fine-tuned on successful agent trajectories, improving its ability to use tools and plan multi-step changes.

**Q: Does it support private repositories?**
A: Yes. MiMo-Code runs locally and never sends source code to external servers when using a local model backend.
