Zed Editor - ModRouter

Zed supports OpenAI-compatible model providers. Point that provider at ModRouter.

Endpoint

https://api.modrouter.online/openai/v1

Example Settings

Add a ModRouter provider in Zed settings:

{
  "language_models": {
    "openai_compatible": {
      "ModRouter": {
        "api_url": "https://api.modrouter.online/openai/v1",
        "api_key": "${MODROUTER_API_KEY}",
        "available_models": [
          {
            "name": "openai/gpt-4o-mini",
            "display_name": "GPT via ModRouter",
            "max_tokens": 128000
          },
          {
            "name": "anthropic/claude-sonnet-4-5",
            "display_name": "Claude via ModRouter",
            "max_tokens": 200000
          }
        ]
      }
    }
  }
}

Use the exact settings shape supported by your Zed version; the important part is that the OpenAI-compatible API URL points at ModRouter’s /openai/v1 endpoint.

Notes

Use a ModRouter virtual key for access control and usage limits.
Configure separate Zed provider entries if different teams or projects need different virtual keys.
Pick models that support the tool behavior required by Zed’s assistant features.
