# Gemini CLI + Luma Cloud Gemini CLI's documented connection uses Google services rather than a generic OpenAI-compatible provider. API connection: No direct connection. Instructions checked: 2026-09-28. Client capabilities and versions may vary; follow the verification steps below. This is an API setup guide. SuperGPT desktop installation and sign-in are separate; use a customer API key for the client described here. ## Before you start - Use a client with a documented OpenAI-compatible custom provider for direct Luma API access. ## Setup 1. **Check the supported connection** Gemini CLI documents Google sign-in, a Gemini API key, and Vertex AI. GOOGLE_GEMINI_BASE_URL changes the destination of Gemini-format requests; it does not turn them into Chat Completions or Responses. 2. **Use a compatible agent** Choose OpenCode, Aider, or another client in this directory for Luma. Keep your Google login and Gemini CLI settings unchanged. ## Verify - No direct Luma setup is claimed for Gemini CLI. Verify the alternative client using its own guide. ## Limits - Do not enter a Luma key as GEMINI_API_KEY or assume that an OpenAI-compatible URL supports Gemini's API format. - Luma does not document a Gemini/Vertex endpoint. A separate translator would need its own compatibility testing. ## Troubleshooting ### GOOGLE_GEMINI_BASE_URL points to Luma but requests fail The setting changes where Gemini-format requests go; it does not translate them into Chat Completions. Restore the override you added and use a documented OpenAI-compatible client for Luma. ### GEMINI_API_KEY rejects the Luma key These keys belong to different services. Keep your Google credentials in Gemini CLI and enter the Luma portable key only in a compatible client's own configuration. ### A Google sign-in or Gemini model picker succeeds That verifies the Google connection, not Luma billing or API access. For a Luma test, follow the OpenCode or Aider guide and check the matching named key in the Luma dashboard. ## Official client documentation - [Gemini CLI: authentication methods](https://geminicli.com/docs/get-started/authentication/) - [Gemini CLI: base URL configuration](https://geminicli.com/docs/reference/configuration/)
