Hello Google AI Team, I am requesting allowlist access for the Audio Output (TTS) modality for the following project. I am trying to use the Batch API but its giving the error below. My code does work fine with both the models using the Non Batch API route but that is a bit difficult to use and costs twice as much.
Project ID: gen-lang-client → LifeMantraTest2
Account Tier: Paid Tier 1
Models Requested: gemini-2.5-flash-preview-tts, gemini-2.5-pro-preview-tts
Use Case: Developing a professional Marathi audiobook portal for long-form content (5,000+ words).
Current Error: BadRequest: You are not allowlisted to request audio output.
