Hi , We run a production real-time voice-AI calling platform on Vertex AI and would like to request allowlist / product-gate access to the following Gemini Live (bidirectional streaming) preview models for our Google Cloud project. Project ID: selldo-voice-ai Billing account: Primary region: us-central1 (also requesting: global) API surface: Vertex AI Live API — LlmBidiService/BidiGenerateContent (WebSocket) Models requested (Vertex publisher IDs): 1. gemini-3.8-live 2. gemini-3.8-live-extended-thinking 3. gemini-3.1-flash-live-preview Observed behavior (why we believe this is a gate, not a config issue): - Unary catalog GET publishers/google/models/gemini-3.8-live returns launchStage=GA at us-central1. - Opening a Live session (BidiGenerateContent) for the same model returns: 1008 “Publisher model projects/selldo-voice-ai/locations/us-central1/ publishers/google/models/gemini-3.8-live was not found or [no access]”. - Same 1008 at location=global (model not published there). - The model does NOT appear in ListModels (publishers/google/models), while GA models we already use do. - Reproduced with google-genai 1.71.0 (vertexai=True) and 2.23.0 (enterprise=True); service-account auth (ADC) is correct and other Gemini models on this project work. Stack: Python google-genai + google-adk (Vertex AI backend), service-account auth. GA Live model gemini-live-2.5-flash-native-audio already works for us at us-central1, so the integration itself is proven; we only need access to the 3.x Live SKUs above. Business context: \. Could you add project selldo-voice-ai to the Live-API allowlist for these models, or point us to the correct preview-access form? Happy to provide any additional details. Thanks, Vinayak Katkar ---
