REASONING

Not published

Only provider-documented reasoning controls are shown; missing controls remain unpublished rather than inferred.

INPUT

text

Input modalities come from the cited official model documentation.

OUTPUT

audio

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

PRICING STATUS

Official paid API.

$0.50 input · $0.125 cached · $6.00 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 lists Gemini 3.8 Flash-Lite TTS as generally available as of September 22, 2026 and as the production replacement for gemini-3.1-flash-tts-preview.

Standard pricing uses text input tokens and audio output tokens; audio output tokens correspond to 25 tokens per second.

The model is excluded from the generic generative token calculator because its output-token dimension represents audio rather than text.
