o2lma

o2lma is a lightweight proxy server that transforms API requests compatible with DeepSeek or OpenAI formats into Ollama API requests. This enables tools like VSCode Copilot Chat to interact with third-party APIs through Ollama.

Features

• API Compatibility: Converts DeepSeek/OpenAI-style requests to Ollama-compatible requests.
• Flexible Configuration: Supports custom base URLs and API keys via command-line arguments or environment variables.
• Lightweight: Built with Hono for minimal overhead.
• Easy Setup: Simple installation and quick start with npm.

Installation

• Clone the repository:

  git clone https://github.com/wrtx-dev/o2lma.git
  cd o2lma
  

• Install dependencies:

  npm install
  

• Build the project:

  npm run build
  

Configuration

Configure the server using either command-line arguments or environment variables:

Command-line options:

npx o2lma --url [API_BASE_URL] --apikey [API_KEY] --host [HOST] --port [PORT] --cap [CAPABILITIES]

Options:

• --url: Base API URL (default: https://api.deepseek.com)
• --apikey: API key for authentication
• --host: Server host (default: localhost)
• --port: Server port (default: 11434)
• --cap: Additional capabilities (options: tools, thinking)

Environment variables:

export BASE_URL="https://api.deepseek.com"
export API_KEY="your-api-key"

Usage

• Start the server:

  npm start
  

  Or for development:

  npm run dev
  

• The server will run on http://localhost:11434 by default (configurable via --host and --port)

• Configure your client (e.g., VSCode Copilot) to use this local endpoint

API Endpoints

The server provides the following endpoints compatible with Ollama API:

• GET /api/version - Returns server version
• POST /api/show - Returns model capabilities
• GET /api/tags - Lists available models
• POST /v1/chat/completions - Proxies chat completion requests
