   Known issues

   There is currently a known issue using Claude Coder with CodeGate muxing. We are working on a fix which we expect to release in CodeGate v0.1.19.

   First, configure your provider(s) and select a model for each of your workspace(s) in the CodeGate dashboard.

   In the Provider Settings settings, select OpenAI Compatible. Set the Base URL to http://localhost:8989/v1/mux.

   Enter anything you want into the Model ID and API key fields; these are not used since the actual provider and model is determined by your CodeGate workspace.

   OpenAI

   You need an OpenAI API account to use this provider. To use a different OpenAI-compatible endpoint, set the CODEGATE_OPENAI_URL configuration parameter when you launch CodeGate.

   In the Provider Settings settings, select OpenAI Compatible. Set the Base URL to http://localhost:8989/openai.

   Enter the Model ID and your OpenAI API key. A reasoning model like o1-mini or o3-mini is recommended.

   OpenRouter

   You need an OpenRouter account to use this provider.

   In the Provider Settings settings, select OpenAI Compatible. Set the Base URL to http://localhost:8989/openrouter.

   Enter your preferred model for the Model ID (example: anthropic/claude-3.5-sonnet) and add your OpenRouter API key.

4. Click Save Settings and confirm that you want to apply the model.
