Gemini 3.5 Transcribe Live

The batch sibling `gemini-3.5-transcribe` is listed in the Gemini API and returns ZERO output tokens on every request shape tried, while gemini-3.5-flash transcribes the same bytes in the same body — so only the Live model is measurable. 4.9% substitutions puts its hearing third on the board; it loses on 6.9% deletions.

ESTIMATE, not a published per-minute rate. Google prices this model per token -- $3.50/1M audio in, $21.00/1M text out -- and the ~$0.005/min + ~$0.004/min figures on the pricing page are Google's own estimate at 25 audio tokens/sec input and 175 text tokens/min output, for a blended ~$0.009/min. Speech density moves it, so read it as an order of magnitude rather than a rate card. Every other price on this column is the vendor's published per-minute rate.
