Google launches Gemini Decision 1 to answer 1,000 closed questions in one pass

At a glance

Google DeepMind has released the Gemini Decisions API for quick, closed-ended choices such as yes/no questions, multiple choice, and ratings. Its underlying model, Gemini Decision 1, can handle up to 1,000 independent questions at once across text, images, audio, video, and PDFs.

Key points

1. 1

   Each answer comes with a probability and a confidence value.

2. 2

   Responses arrive in 150 to 250 milliseconds.

3. 3

   Google says it already uses the API for model routing in Gemini Notebook, design prototyping in Stitch, and safety checks in Google Search.

4. 4

   The price is $0.10 per million input tokens with no output charge, which Google says is about five times cheaper than Gemini 3.5 Flash-Lite.

Why it matters

It signals a shift toward AI tools that quickly and cheaply pick fixed answers rather than writing long text. Several companies have released similar models in recent weeks.
