Connect an OpenRouter Key

Learn how to create an OpenRouter API key and configure Automix to use it as your language-model provider, with options for workspaces that restrict usage to free models only.

Takes About 10 minutes.

  1. 1 Create an OpenRouter API key

    Sign in to your OpenRouter account and navigate to the API keys page. Create a new key and copy it immediately, as you may not be able to retrieve it later. Note that a key is required even if you only plan to use OpenRouter's free models; free models bill zero against the key, but the key itself is still necessary for authentication.

  2. 2 Set the provider and paste the key

    In your Automix workspace, go to Settings and locate the LLM & Providers section. Set the provider to OpenRouter and paste the API key you created in the previous step. The base URL and a default model are filled in automatically for the OpenRouter preset, so you do not need to configure these manually. Save the setting to apply the changes.

    Environment variables: LLM_PROVIDER, LLM_API_KEY

  3. 3 Optional: use more than one key

    If you have more than one OpenRouter account or key, you can enter them as a comma-separated pool in the key field instead of using a single key. Automix will rotate across the pool to distribute load, rather than requiring you to select one key for all requests.

    Environment variables: LLM_API_KEYS

After connecting

  • Automix's assistant and agent features will now send their generation requests through your OpenRouter key.
  • You can switch which specific OpenRouter model is used later in the settings without needing to repeat the key setup.
