Overview

Multimodal decision model served only through Google's new Decisions API (API id gemini-decision-1, v1beta endpoint). It generates no text: it scores options directly and returns calibrated probabilities for yes/no, multiple-choice and rubric-score questions with zero output tokens, aimed at routing, ranking, classification and grading steps inside agent pipelines. Up to 1,000 independent questions per request against one shared input, 262,144-token context. Input-only pricing of $0.10 per MTok. Google states no release stage, and publishes no named benchmark figures, only chart images. None of the tracked benchmarks apply to a model that produces no text, so every benchmark field stays empty and the model takes no part in any ranking.

Benchmarks

No benchmark values are recorded for this model.
