+ADK uses the `GOOGLE_GENAI_USE_ENTERPRISE` environment variable to determine which Live API platform to use:
 
-- `GOOGLE_GENAI_USE_VERTEXAI=FALSE` (or not set): Uses Gemini Live API via Google AI Studio
-- `GOOGLE_GENAI_USE_VERTEXAI=TRUE`: Uses Gemini Live API (Agent Platform) via Google Cloud
+- `GOOGLE_GENAI_USE_ENTERPRISE=FALSE` (or not set): Uses Gemini Live API via Google AI Studio
+- `GOOGLE_GENAI_USE_ENTERPRISE=TRUE`: Uses Gemini Live API (Agent Platform) via Google Cloud
 
 This environment variable is read by the underlying `google-genai` SDK when ADK creates the LLM connection. No code changes are needed when switching platforms—only environment configuration changes.
