🍋 Lemonade for GitHub Copilot

Lemonade allows you to use local LLMs on GitHub Copilot Chat!

🚀 Getting Started

1. Make sure Lemonade is running
   • We recommend setting the context size to at least 32k by using the Lemonade tray or --ctx-size cli option.
2. Install the Lemonade for GitHub Copilot extension
3. Open VS Code's chat interface, click the model picker, and click "Manage Models..."
4. Select "Lemonade" provider and choose a model (Qwen3-Coder-30B is a great start!)

You can now start chatting with your local LLM models! 🥳

NOTE: If needed, configure a custom server URL using the "Manage Lemonade Provider" command

🌟 Why Choose Lemonade for Copilot?

Requirements

• VS Code 1.104.0 or higher
• Lemonade server 8.1.10 or higher

🔧 Configuration

The extension connects to http://localhost:8000/api/v1 by default. You can change this by:

1. Opening VS Code Command Palette (Ctrl+Shift+P)
2. Running "Manage Lemonade Provider" command
3. Entering your custom Lemonade server URL
4. Optionally, entering your API key (if your server has LEMONADE_API_KEY configured)

Environment Variables

Variable	Default	Description
LEMONADE_CTX_SIZE	128000	Context window size (in tokens) reported to VS Code. Set this to match the --ctx-size value used when starting Lemonade so the model picker displays the correct context limits. For example, LEMONADE_CTX_SIZE=262144 for a 256 k context window.

Tip: Launch VS Code from a terminal where LEMONADE_CTX_SIZE is already set, or add it to your system/user environment variables so it is always picked up.
