🚀 Xiaomi MiMo GitHub Copilot Chat
Use MiMo AI models directly in GitHub Copilot Chat — no Copilot Pro/Enterprise subscription needed. Just bring your own API key (BYOK).
💡 What Is This?
Xiaomi MiMo GitHub Copilot Chat is a free, open-source VS Code extension that brings Xiaomi MiMo AI models into GitHub Copilot Chat via the official VS Code Language Model Chat Provider API.
Why Xiaomi MiMo GitHub Copilot Chat?
- 🔑 No Copilot Pro/Enterprise needed — just sign in with a free GitHub account

- ⚡ MiMo V2.5 — 1M token context window, top-tier performance at fraction of the cost
- 🧩 Seamless integration — appears in the Copilot Chat model picker like GPT-4 or Claude
- 🛡️ Private & secure — API key stored locally via VS Code SecretStorage, no telemetry

✨ Features
- BYOK — configure MiMo with your Xiaomi API key
- Live model list — fetches available models directly from MiMo API on every startup
- Bundled fallback — keeps the picker usable offline with an internal fallback catalog when live metadata cannot be refreshed
- Tool-calling support — forwards tool schemas using the OAI-compatible request shape
- Native transport — all models use OpenAI-compatible
/chat/completions endpoint
- Safer requests — adds request and stream idle timeouts with clearer rate-limit/quota errors in VS Code
- Diagnostics command — one-click markdown report showing exactly which models VS Code has registered plus recent request summaries
- Usage status bar — shows the latest prompt/output/total/cache summary after each MiMo response
Requirements
- VS Code 1.120.0 or higher with the Language Model Chat Provider API
- GitHub Copilot Chat extension — install from marketplace (required — this extension only adds models into Copilot Chat)
- Sign in to GitHub Copilot Chat (a personal GitHub account is sufficient — no Copilot Pro/Enterprise needed for BYOK)
- A MiMo API key — get one from Xiaomi MiMo
⚡ Quick Start
- Install GitHub Copilot Chat from the marketplace if you haven't already.
- Install this extension (or press
F5 in the repo to launch an Extension Development Host).
- Open GitHub Copilot Chat (click the Copilot icon in the sidebar or press
Cmd+Shift+I / Ctrl+Shift+I).
- Click the model picker (current model name) → Manage Models…
- Select MiMo.
- Press
Enter to accept the default Group Name.
- Enter your MiMo API Key when prompted — VS Code stores it securely as a secret.
- Choose the models you want available.
- Select any MiMo model from the picker and start chatting.
💡 Tip: Registered models are automatically available in the Copilot Chat model picker — no extra setup needed. If a model appears in the Language Models view but not in the chat picker, hover its row and click the eye icon (👁) to enable visibility.
Commands
Once installed, MiMo models appear directly in the GitHub Copilot Chat model picker — no special commands needed. The easiest way to manage your API key is via Settings → Language Models (gear icon ⚙).
For advanced usage, you can also run these commands via the Command Palette (Cmd+Shift+P / Ctrl+Shift+P):
| Command |
Description |
MiMo: Manage Provider |
Manage API key, refresh models, or test connection |
MiMo: Set API Key |
Store or update your MiMo API key |
MiMo: Diagnostics |
Show a markdown report of registered MiMo models and recent request summaries |
Note: The native BYOK flow via Language Models (gear icon ⚙) is recommended. VS Code will ask for a group name, then the matching API key.
