Gemini Decision 1 and the Gemini Decisions API

Google released a scoring-only Gemini model that answers up to 1,000 yes/no, multiple-choice or rubric questions about one multimodal input in a single pass.

Available through the Gemini API in Google AI Studio as gemini-decision-1. Instead of generating text it returns probabilities and confidence scores, which Google pitches for routing, policy checks and grading, with 150-250 ms end-to-end latency and inputs up to 256K tokens across text, images, audio, video and PDFs. Google says it already powers model routing in Gemini Notebook and tools in Stitch and Search; Google Cloud support is coming later.
