# GeminiEndpointConfig Gemini backend routing. DEVELOPER does not use projectId or location; GOOGLE_CLOUD requires projectId and defaults an omitted location to global. ```python from goodmem.models import GeminiEndpointConfig ``` - `backend` (`GeminiApiBackend | None`, required): Google API surface. UNSPECIFIED is invalid when this configuration is supplied on a write. - `project_id` (`str | None`, optional): Google Cloud resource project. Required for GOOGLE_CLOUD and unused for DEVELOPER; this is distinct from the ADC quota project. JSON: `projectId`. - `location` (`str | None`, optional): Google Cloud location. Valid only for GOOGLE_CLOUD; omission defaults to global. [Python](../../python.md) Related types — open only those used by your request: - [GeminiApiBackend](GeminiApiBackend.md)
