Google launches Gemini Decisions API for fast multimodal scoring of up to 1,000 questions per request

Google says the new Gemini Decisions API, running the Gemini Decision 1 model, is available now through the Gemini API in Google AI Studio. It scores up to 1,000 yes/no, choice and rubric questions in one pass over text, images, audio, video and PDFs, returning probabilities and confidence scores in 150-250 ms end-to-end latency. Pricing is $0.10 per 1M input tokens with zero output tokens billed, and the shared input is billed once per request. Google says this makes it nearly 5x cheaper than Gemini 3.5 Flash-Lite on a shared benchmark suite. A no-cost tier covers prototyping, and Google Cloud support is coming soon.
