opencode

Open-source terminal agent, works with any provider.

opencode configures each provider with a base URL rather than reading OPENAI_BASE_URL. The fastest way is the interactive login; for full control, edit the config file.

    Requires Node.js 18 or newer. Installs the global opencode command.

    bash
    npm install -g opencode-ai
  2. 2

  3. 3

    Option B: config file

    Declare an OpenAI-compatible provider with its base URL, key and model. Replace the values with your own.

    ~/.config/opencode/opencode.json
    {
  "$schema": "https://opencode.ai/config.json",
  "provider": {
    "custom": {
      "npm": "@ai-sdk/openai-compatible",
      "options": {
        "baseURL": "https://api.example.com/v1",
        "apiKey": "your-api-key"
      },
      "models": { "your-model-name": {} }
    }
  }
}
  4. 4

    Start coding

    Launch it in your project folder and select your custom model with the /models command.

    bash
    opencode
Tip: opencode does not read OPENAI_BASE_URL or OPENAI_API_KEY for custom endpoints. You must declare the provider, either via auth login or the config file.
Pick a cheaper model or provider first, then plug its key and endpoint into the steps above. Compare prices · Browse providers
