Gemini 3.5 Transcribe API pricing

google/gemini-3.5-transcribe

Speech-to-text with diarization and timestamps. Gemini 3.5 Transcribe by Google, routed through INFRO on a Google account you connect — alongside every other provider you run. Google bills you for it directly, on that account and at your own rate. INFRO adds routing, failover, request logs, cost attribution and policy around it, and takes no part of what you pay Google.
