Gemini Decision 1
by Google Model API in Decision models
Google LLC · google.com since 1997 · status page · who's behind it
Gemini Decision 1 is Google's model for closed-set decisions. It scores yes/no, multiple-choice and rubric questions in one pass and returns probabilities, not text, over text, images, audio, video and PDFs, at $0.10 per million input tokens.
Best for Routing, tool selection, policy checks and rubric grading over mixed media, where many fixed questions share one input and generated text isn't needed.

The same model, listed separately Gemini Developer API (Model API)
Assessment. Google's decision model scores up to 1,000 yes/no, choice and rubric questions per request over a 262,144-token multimodal input, at $0.10 per million input tokens, no output charge and a free tier. It is on a v1beta endpoint with no caching or batch discount, so repeated input is paid in full, and every speed and accuracy figure is Google's.

From our research 11 facts checked against the vendor's pages
- Surface graded
- The Decisions endpoint of the Gemini Developer API (v1beta), read from Google's announcement, the Decisions guide, the model page and the pricing page on 11 November 2026, and the request and response types in google-genai 3.2.0. Platform readings (status page, keys, terms, retention, deprecations) are the Gemini API listing's of 1 November. No account was made and nothing was called
- Model ID
- gemini-decision-1, sent as models/gemini-decision-1 in the SDK's request type
- Question types
- noul (yes/no, a calibrated P(true) between 0.01 and 0.99, with optional true and false criteria), choice (2 to 255 mutually exclusive options, the winner and a normalised probability for each) and score (an ordered rubric of 2 to 255 levels from 0, a probability-weighted score and a probability per level). Every answer carries a confidence from 0 to 1
- Google's figures
- Vendor-reported: 150 to 250 ms end to end and 50 to 100 ms median model compute for contexts up to 16K tokens, nearly flat from 1 to 100 questions; leads Google's suite with the lowest calibration error; nearly five times cheaper than Gemini 3.5 Flash-Lite on the same suite. Gemini Notebook routing up to 40% lower latency for everyday queries
- Where
- Gemini API and Google AI Studio now. Gemini in Google Cloud coming soon. Third-party integrations, OpenRouter among them, described as rolling out
- Limits
- 262,144 tokens shared by the input and all questions. 1 to 1,000 questions, keys matching [A-Za-z0-9_-] up to 64 characters. Inline data to 100 MB a request (50 MB for PDFs), Files API URIs, or public or signed HTTPS URLs up to 15 MB each; no YouTube or gs:// sources. Image and video resolution low, medium, high or ultra_high (images only)
- Request and response
- POST /v1beta/decisions with model, input (a string, a block or blocks of text, image, audio, video or PDF) and questions. The response has answers keyed by question id and usage by modality, with output tokens always 0. Conversation history goes in as text
- Errors
- Safety blocks, limit breaches and key failures return HTTP 400, with codes safety, prohibited_content, blocklist, image_safety and content_blocked
- Not supported
- Context caching, Batch API, Flex and Priority inference, function calling, structured outputs, text generation, thinking, grounding and the Live API, per the model page
- Pricing
- $0.10 per million input tokens on the paid tier for every modality, $0 output, free of charge on the free tier, per the pricing page
- Launch stage
- Not stated in the post, the guide or the model page. The endpoint is on v1beta and the model has one version
Facts verified 11 November 2026 from vendor docs, repositories and package registries. JSON · Markdown
Strengths
- Price published without a login: $0.10 per million input tokens and $0 output, with the shared input billed once per request
- A no-cost tier in Google AI Studio, so an agent's operator can start with a key and no card
- Up to 1,000 questions in one request over text, images, audio, video and PDFs, within 262,144 tokens
- Typed request and response models in google-genai 3.2.0 (Apache-2.0), with stated ranges for options, levels and probabilities
- Every answer carries a confidence from 0 to 1, so uncertain cases can go to a larger model or a person
Weaknesses
- No context caching, Batch API, Flex or Priority: the guide says repeated input across requests counts in full
- Launch stage not stated, and the endpoint is on v1beta, which Google says may change
- Free-tier requests are used to improve Google's products, per the pricing page
- Google's latency figures cover contexts up to 16K tokens, not the 262,144-token maximum
- The public rate-limit page has no row for this model; limits are shown only in AI Studio
Before you call it notes for agents
- Call POST /v1beta/decisions or
client.decisions.create(SDK 3.2 or later), not generateContent or the Interactions API - Put every question about the same input in one request: there's no caching, and repeated input is billed in full
- Pass media inline (100 MB, 50 MB for PDFs), as a Files API URI or as an HTTPS URL up to 15 MB; YouTube and gs:// links are refused
- Branch on the HTTP 400 error code (safety, prohibited_content, blocklist, image_safety, content_blocked) before retrying
- Keep question keys to [A-Za-z0-9_-] and 64 characters, and options or levels between 2 and 255

Notable
- Announced on 11 November 2026 by Min Choi (Product Manager) and Felix Yu (Principal Scientist) of Google DeepMind, available the same day through the Gemini API in Google AI Studio source
- Up to 1,000 independent questions per request against one shared input; the guide gives 262,144 tokens for input and questions together, while Google's latency figures (150 to 250 ms end to end) are for contexts up to 16K tokens source
- Google says it leads its own benchmark suite on agent routing, reasoning, ranking and multimodal understanding with the lowest calibration error, and is nearly five times cheaper across that suite than Gemini 3.5 Flash-Lite through the Interactions API. No scores are given in the text (vendor claim, https://blog.google/innovation-and-ai/technology/developers-tools/gemini-decisions-api/)
- Google says Gemini Notebook uses it to route queries to a model tier and thinking level, and Google Search uses it as a safety layer that detects adversarial behaviour in MCP tools source
- google-genai 3.2.0, tagged on 11 November 2026, adds
client.decisions.create, posting to/{api_version}/decisionssource - Gemini in Google Cloud is listed as coming soon, with an interest form; OpenRouter, LangChain, Vercel, LiteLLM, Pydantic AI, Pipecat, LiveKit and OpenCode integrations are described as rolling out source
- The guide says context caching, the Batch API and Flex and Priority inference aren't supported, and that repeated input across requests counts in full source

Fix list 16 items, the biggest gain first
Everything this grade says the listing lacks, from the reasons above, the checklist, the provenance checks, the deductions, what we couldn't check and what the review panel asked for, with the steps, ready to paste into a coding agent working on Gemini Decision 1. A fix counts at the next check, once it's public.
You're lucky. As part of the beta, your first month is free.
What we couldn't check
- unchecked: Decision 1's rate limits. The public rate-limit page has no row for it, and the AI Studio rate-limit page answered with a server error on 11 November.
- unchecked: whether Decisions calls are logged like Generate Content requests.
- unchecked: OpenRouter's model page, which Google's post links as rolling out.
- The post gives latency for contexts up to 16K tokens; the limit is 262,144 tokens, and the two aren't reconciled.
- Launch stage (preview or GA) isn't stated on the post, the guide or the model page.

Probe metrics
Not measured yet. Our benchmark probes haven't run, so there's no availability, latency or error rate from a run and Performance is pending. The live panel above has what the pollers have seen so far, which doesn't change the score.

Agents send the same to POST /api/v1/verify as {"slug": "gemini-decision-1", "url": "…"}, or call the verify_listing tool at /mcp. Ten checks an hour from one address. What we check. To announce the listing, get sharing assets for social media.
