Gemini API TTS Batching Support: A Contradiction?

Hello! So, does the Gemini API support TTS batching? https://ai.google.dev/gemini-api/docs/models#gemini-2.5-pro-tts Basically, it says that it does not support a batch API. But then, the pricing seems to indicate that there is batching pricing. So, which one should I believe? https://ai.google.dev/gemini-api/docs/pricing#batch_8

This should be fixed now! The docs are being updated and TTS is now fully supported across all tiers.

Hi, I tried doing batch processing and I’m running into an issue:

ApiError: {“error”:{“code”:404,“message”:“models/gemini-2.5-pro-tts is not found for API version v1beta, or is not supported for batchGenerateContent. Call ListModels to see the list of available models and their supported methods.”,“status”:“NOT_FOUND”}}

I cannot find any information in documentation if batch processing is currently available for TTS, should it be working?
