Google launches Gemini Decisions API and Gemini Decision 1 model for closed-set scoring
Overview
Google launches the Gemini Decisions API, powered by its Gemini Decision 1 model, for yes/no, multiple-choice, and rubric questions across text, images, audio, video, and PDFs.
The model scores up to 1,000 questions per request and returns probabilities and confidence values, with zero output tokens billed. Google prices input at $0.10 per 1M tokens and says it is about five times cheaper than Gemini 3.5 Flash-Lite. A free tier is available in Google AI Studio for prototyping, with a stated limit of 200 requests per minute, 50K tokens, and 10K requests per day, according to a Chinese-language post. Integrations with OpenRouter, LangChain, Vercel and others are rolling out, and Gemini on Google Cloud support is listed as coming soon.
Artificial Analysis reports Gemini Decision 1 scores 66 on its Decision Index v2.1, seven points behind Drex Max v1.1 and GLiDE v1.2, which both score 73. It costs $345 per 1M tasks, more than three times Drex Max v1.1's $103, and runs at 211ms per task. Artificial Analysis says it leads decision models on knowledge and reasoning evaluations but trails on AA-Paperclip. Google's own claims include beating OpenAI's Decisions API on seven of nine benchmarks, as reported by SiliconANGLE; Jev is cheaper per token, according to the same report and a separate post by Santiago.
