Use Crazyrouter models in OpenCode

OpenCode's provider system takes any OpenAI-compatible endpoint. The setup script writes the provider block, a curated model list and sensible defaults, then verifies the key.

One-command setup

The script is idempotent — re-run it to change the default model. Add more models by extending the models map; names must match the Crazyrouter catalogue.

  1. 1Run the command

    Pulls the script from GitHub; nothing else is downloaded.

  2. 2Paste your Crazyrouter key

    Pick a default model when asked; you can change it later.

  3. 3Tool talks to Crazyrouter

    Config or env vars are written; the next launch routes through your key.

macOS / Linux
curl -fsSL https://raw.githubusercontent.com/xujfcn/opencode-crazyrouter/main/setup.sh | bash
What the script does
  • Checks that opencode, curl and python3 are present
  • Adds a crazyrouter provider to ~/.config/opencode/opencode.json with a preloaded model list
  • Sets the default and small model, then calls /v1/models to verify the key
  • Non-interactive: bash <(curl -fsSL …/setup.sh) --yes --model claude-sonnet-4-6

Scripts are fetched from the public GitHub repo linked below. Read them before piping to a shell if that's your policy; the download-then-run form is in the README.

FAQ

What is small_model for?

OpenCode uses it for cheap internal tasks like titles and summaries; deepseek-v4-flash keeps that cost near zero.

Why @ai-sdk/openai-compatible?

It's the provider adapter OpenCode uses for any OpenAI-shaped endpoint; Crazyrouter speaks that protocol.

Can I keep other providers?

Yes — the script only adds the crazyrouter key under provider and updates model / small_model.
