CAPABILITY CONTRACT

Published model behavior.

REASONING

minimal · medium · high · default medium

Only provider-documented reasoning controls are shown; missing controls remain unpublished rather than inferred.

INPUT

text + image + video + PDF

Input modalities come from the cited official model documentation.

OUTPUT

text + image

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

PRICING STATUS

Official paid API.

$1.50 input · $30.00 output per 1 million tokens (IMAGE output; text output billed separately).

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.

01

Standard paid API input: $1.50 per 1M text/image/video input tokens; generated IMAGE output: $30.00 per 1M IMAGE output tokens. Text and thinking output is separately priced at $7.50 per 1M text tokens; do not apply the image rate to text.

02

Google estimates $0.0336 per 1K image, $0.0504 per 2K image and $0.113 per 4K image in Standard mode. Input prompts, Search grounding, Batch and additional output tokens may incur separate charges.

03

Stable provider-native ID gemini-nano-banana-2.1. The generative text-token cost calculator is intentionally disabled because output mixes image and text tokens.
