🎯 Problem

OpenRouter provides access to various AI models from OpenAI, Anthropic, and others. However, GitHub Copilot's Agent Mode requires models to support function calling/tools, but OpenRouter's API doesn't announce tool support for its models.

This prevents using powerful models like Claude, GPT-4, and others through OpenRouter with Copilot's advanced Agent Mode features.

✨ Solution

copilot-ollama creates a local proxy chain that:

• 🔄 Forwards requests to OpenRouter while preserving tool support
• 🛠️ Makes OpenRouter models compatible with Copilot's Ollama integration
• 🚀 Enables Agent Mode with any OpenRouter model
• 🔧 Uses LiteLLM for OpenAI-compatible proxying
• 🔗 Uses oai2ollama for Ollama compatibility

🚀 Quick Start

Prerequisites

• uv package manager
• OpenRouter API key (get one here)
• VSCode with GitHub Copilot extension

Installation & Setup

1. Clone and navigate to the project

   git clone https://github.com/bascodes/copilot-ollama.git
   cd copilot-ollama

2. Set your OpenRouter API key

   export OPENROUTER_API_KEY=your_openrouter_api_key_here

3. Start the proxy servers

4. Configure VSCode

   • Open VSCode settings
   • Set github.copilot.chat.byok.ollamaEndpoint to http://localhost:11434
   • Click "Manage Models" → Select "Ollama"

5. Start coding! 🎉 Your OpenRouter models are now available in Copilot Agent Mode.

⚙️ Configuration

Adding Models

Edit config.yaml to add or modify available models:

# This section defines the models that your local proxy will advertise
model_list:
  - model_name: kimi-k2  # Name that appears in VSCode
    litellm_params:
      model: openrouter/moonshotai/kimi-k2  # Actual OpenRouter model

  - model_name: claude-3-sonnet
    litellm_params:
      model: openrouter/anthropic/claude-3-sonnet

  - model_name: gpt-4-turbo
    litellm_params:
      model: openrouter/openai/gpt-4-turbo

🔧 How It Works

graph LR
    A[VSCode Copilot] --> B[oai2ollama<br/>:11434]
    B --> C[LiteLLM Proxy<br/>:4000]
    C --> D[OpenRouter API]
    D --> E[AI Models<br/>Claude, GPT-4, etc.]

1. VSCode Copilot sends requests to what it thinks is an Ollama server
2. oai2ollama translates Ollama API calls to OpenAI format
3. LiteLLM proxies OpenAI-compatible requests to OpenRouter
4. OpenRouter routes to the actual AI model providers
5. Tool/function calling capabilities are preserved throughout the chain
