REASONING

Not published

Only provider-documented reasoning controls are shown; missing controls remain unpublished rather than inferred.

INPUT

audio

Input modalities come from the cited official model documentation.

OUTPUT

text

Output modality and output-limit claims remain separate so an undocumented token cap is not guessed.

PRICING STATUS

Official paid API.

$2.00 input · $12.00 output per 1 million tokens.

SXF preserves the provider-published native billing basis. Only calculator-eligible generative token models enter token-cost arithmetic; specialist units and input-only embeddings remain visible without forced conversion.

CAVEATS

What the source record does not assume.

Google announced Gemini 3.5 Transcribe as generally available on August 26, 2026, with no shutdown date currently announced.

The model accepts audio and returns text/word annotations; Google documents up to one hour of audio per request, or up to 30 minutes when diarization or word-level timestamps are enabled.

Standard pricing is $2 per 1M audio input tokens and $12 per 1M text output tokens. The model is excluded from the generic text-token calculator because the input token dimension is audio-specific.
