Zed Editor

Reviewed by Proof · Updated

Definition

Zed is a code editor with built-in AI features that can use luv13 as an OpenAI-compatible provider.

Key takeaways

  • In Zed, add luv13 as an OpenAI-compatible provider, either from Agent Settings or in settings.json.
  • The settings live under language_models.openai_compatible, with api_url set to https://api.luv13.ai/v1.
  • Each model needs a name (the luv13 id) and a max_tokens value, which Zed treats as the context window.
  • If you name the provider luv13, Zed reads the key from the LUV13_API_KEY environment variable.
  • These names come from Zed's official "Use API Access" docs.

Setup from the UI

  1. Run agent: open settings from the command palette.
  2. In the LLM Providers section, choose Add Provider.
  3. Fill in the provider name, API URL (https://api.luv13.ai/v1), model id (luv13/glm-5.3-flash), and a context window.
  4. Enter your luv13 key when asked. Zed stores it in your system keychain, not in settings.json.

Setup in settings.json

{
  "language_models": {
    "openai_compatible": {
      "luv13": {
        "api_url": "https://api.luv13.ai/v1",
        "available_models": [
          {
            "name": "luv13/glm-5.3-flash",
            "display_name": "GLM 5.3 Flash (luv13)",
            "max_tokens": 32000
          }
        ]
      }
    }
  }
}

The 32000 above is only an example value. Zed requires a number here, but luv13's model list doesn't publish context lengths, so pick a conservative value or ask the operator. See Context Window.

The API key

Zed builds the environment variable name from the provider id in upper snake case plus _API_KEY. A provider id of luv13 reads LUV13_API_KEY, the same name these docs use. A non-empty environment variable takes priority over a key saved in the keychain. Don't put the key in settings.json.

Capabilities

Zed assumes OpenAI-compatible models support tools and not images unless you set capabilities. Check Tool Calling on luv13 and Image Input for what luv13 supports, and adjust if needed.
