Zed setup

Zed's agent panel can use any OpenAI-compatible API. Point its OpenAI provider at Claudech and list the models you want.

Before you start#

• A Claudech API key from API keys. API access unlocks after your first purchase.

Configuration#

Add this to ~/.config/zed/settings.json (open it with zed: open settings):

{
  "language_models": {
    "openai": {
      "api_url": "https://api.claudech.com/v1",
      "available_models": [
        { "name": "claude-opus-5-5", "display_name": "Claude Opus 5.5", "max_tokens": 1000000, "max_output_tokens": 65536 },
        { "name": "claude-fable-5-1", "display_name": "Claude Fable 5.1", "max_tokens": 1000000, "max_output_tokens": 131072 },
        { "name": "claude-sonnet-5", "display_name": "Claude Sonnet 5", "max_tokens": 1000000, "max_output_tokens": 32768 }
      ]
    }
  }
}

max_tokens is the context window and max_output_tokens the longest reply; the values above match the Models page.

Then open the agent panel's settings, find the OpenAI provider and paste your sk-... key. Pick a Claudech model from the model selector.
