November 11: The Decoder adds that integrations are still rolling out, Google claims the lowest Top-1 ECE, and OpenAI, Cloudflare, and Microsoft recently shipped similar models.

Merged summary · x-ai/grok-4.7 · rewritten as coverage arrivesSummaries by Vani AI

Google’s Gemini Decisions API scores up to 1,000 closed-set questions in one pass, with probabilities returned in 150–250 ms.

Google DeepMind introduced the Gemini Decisions API, powered by Gemini Decision 1 (gemini-decision-1), in the Gemini API and Google AI Studio. One request can score yes/no, multiple-choice, and rubric or scale questions over text, images, audio, video, and PDFs, returning probabilities and confidence rather than generated text. Google says end-to-end latency is 150–250 ms and pricing is $0.10 per million input tokens with output tokens free, nearly five times cheaper than Gemini 3.5 Flash-Lite. Internal uses include Gemini Notebook routing, Stitch, and Search safety checks. The Decoder reports integrations are still rolling out and that Google claims the lowest Top-1 ECE calibration error.

Key facts
  • Input can mix modalities up to 256K tokens and 1,000 questions.
  • Choice questions cover 2 to 255 options, each with a probability.
  • Google cites 50–100 ms of model compute.
  • Search uses it to flag adversarial behavior against MCP tools.
  • A no-cost prototyping tier is available in Google AI Studio.
  • OpenRouter, LangChain, and Vercel integrations are still rolling out.
