Google's Decisions endpoint returns probabilities, not text, at $0.10 per million tokens

What this means for you

Nothing to act on yet. The interesting part is the interface: one call returns a probability per question, rather than a label you post-process into a threshold yourself. But with no calibration testing, no output price and no availability date, any cutoff you set today is a guess.

Google has launched an API whose model returns probabilities rather than prose. Gemini Decision 1 answers up to 1,000 yes/no, multiple-choice or rubric questions per request, over text, images, audio, video and PDFs, and the Gemini Decisions API charges $0.10 per million input tokens. Google describes the outputs as calibrated — a stated 70% should be right about 70% of the time — and no evaluation of that calibration is given. Output pricing, availability date and regional limits are absent from the report.
