Looking to self-host your own model? Check out the OpenAI Compatible provider.
To use Ask Sourcebot you must define at least one Language Model Provider. These providers are defined within the config file you provide Sourcebot.
Example config with language model provider

    "$schema": "https://raw.githubusercontent.com/sourcebot-dev/sourcebot/main/schemas/v3/index.json",
    "models": [
        // 1. Google Vertex config for Gemini 2.5 Pro
        {
            "provider": "google-vertex",
            "model": "gemini-2.5-pro",
