Use Redline in Zed

Zed's Agent Panel supports an openai_compatible provider. Declare it in settings.json with the model list; the key is entered through the UI so it stays in the keychain.

An openai_compatible provider

In settings.json:

{
  "language_models": {
    "openai_compatible": {
      "redline": {
        "api_url": "https://redline-gateway.pages.dev/v1",
        "available_models": [
          {
            "name": "deepseek/deepseek-chat-v3.1",
            "display_name": "DeepSeek Chat v3.1 (Redline)",
            "max_tokens": 163840
          }
        ]
      }
    }
  }
}

Add the key through Agent Settings, "Add Provider" (it is stored in your OS keychain, never in the settings file). Each model's capabilities.tools defaults to true; set it to false for a non-tool model. Zed's inline edit predictions need a legacy completions endpoint Redline does not serve, so use Redline for the Agent Panel chat and edits, not for edit predictions.
