Confidence: medium. Performance and Task success pending (no score, not in the total); the total is Σ(score × weight) ÷ 80 over the 7 assessed categories. "This run" is each category's share of the 100 points. | Category | Weight | This run | Score (0–100) | Points | | --- | --- | --- | --- | --- | | Reliability | 16% | 20 | 40 | 8.0 | | Performance | 10% | pending | pending | n/a | | Schema & documentation | 13% | 16.2 | 80 | 13.0 | | Agent ergonomics | 13% | 16.2 | 85 | 13.8 | | Security & auth | 14% | 17.5 | 45 | 7.9 | | Payments & pricing | 10% | 12.5 | 60 | 7.5 | | Task success | 10% | pending | pending | n/a | | Maintenance & community | 7% | 8.8 | 79 | 6.9 | | Transparency & trust (editorial 50, provenance 89) | 7% | 8.8 | 70 | 6.1 | | Negative events | up to −15 | up to −15 | none recorded | 0 | | **Total** | | | | **63.2 → B** | ### Why each score - Reliability 40 (checked 2026-11-11): Model reading for gemini-decision-1 on the Gemini API's Decisions endpoint. Platform facts are the Gemini API listing's (gemini-api, re-read 1 November), carried over as RULES.md allows for a model on an already graded platform. Status page at aistudio.google.com/status with no readable components or history (10 of 20) and no readable incident record (5 of 30). Rate-limit tiers and spend limits published for the platform, but the public rate-limit page, read on 11 November, has no row for Decision 1 and sends you to AI Studio (5 of 15). Backoff guidance for 429 and 503 and SDK retries (15). No SLA (0). The guide and the model page, read on 11 November, state no launch stage; the endpoint is v1beta and the model has one version, so half, as Gemini 4 Carbon was read (5 of 10). 10 + 5 + 5 + 15 + 0 + 5 = 40. - Performance: Pending. Latency is measured per call by our probes, which haven't run yet, so this run doesn't score it. Its weight is shared across the assessed categories until the first probe window closes. - Schema & documentation 80 (checked 2026-11-11): Model reading for gemini-decision-1 on the Gemini API's Decisions endpoint. Platform facts are the Gemini API listing's (gemini-api, re-read 1 November), carried over as RULES.md allows for a model on an already graded platform. No published machine-readable contract for the Decisions endpoint; the request and response types are generated and typed in google-genai 3.2.0, Apache-2.0 (10 of 25). llms.txt with Markdown twins on the platform (10). The guide and model page say what the endpoint is for and list what it doesn't do (no caching, Batch, Flex, Priority, function calling, structured outputs or text generation; no YouTube or gs:// sources; history only as text) (18 of 20). Fields carry stated rules: question keys match [A-Za-z0-9_-]+ up to 64 characters, 1 to 1,000 questions, 2 to 255 options or levels, option keys 1 to 128 characters, P(true) between 0.01 and 0.99, nesting to 100 levels (14 of 15). Python, JavaScript and REST examples, and errors documented as HTTP 400 with codes safety, prohibited_content, blocklist, image_safety and content_blocked (13 of 15). Dated SDK changelog and the platform's dated changelog (15). 10 + 10 + 18 + 14 + 13 + 15 = 80. - Agent ergonomics 85 (checked 2026-11-11): Read on the tool lines, as the other decision-model listings are. Model reading for gemini-decision-1 on the Gemini API's Decisions endpoint. Platform facts are the Gemini API listing's (gemini-api, re-read 1 November), carried over as RULES.md allows for a model on an already graded platform. Answers are probabilities only, and the shared input is billed once across up to 1,000 questions (25 of 25). Limits are written down: 262,144 tokens shared by the input and all questions, 1,000 questions, 2 to 255 options, inline data to 100 MB (50 MB for PDFs), 15 MB per external URL (20 of 20). Errors return HTTP 400 with a named code an agent can branch on, plus the platform's backoff advice (15 of 20). SDK retries and backoff guidance, no idempotency key; nothing is written, so a repeat only costs input again (10 of 20). Three required fields, SDK 3.2 or later in Python and JavaScript, and REST (15 of 15). 25 + 20 + 15 + 10 + 15 = 85. - Security & auth 45 (checked 2026-11-11): Model reading for gemini-decision-1 on the Gemini API's Decisions endpoint. Platform facts are the Gemini API listing's (gemini-api, re-read 1 November), carried over as RULES.md allows for a model on an already graded platform. Keys bound to a service account and restricted to the Gemini API, with no scopes and a token accepted in the URL (15 of 30, the platform's deduction). The pricing page, read on 11 November, says free-tier content is used to improve Google's products and paid-tier content isn't (10 of 20, the platform's reading). Abuse retention with no number (5 of 15). Request logs for billed projects are described for Generate Content; the Decisions guide says nothing on logging (10 of 15). security.txt and a reward programme, no certification naming the API (5 of 20). 15 + 10 + 5 + 10 + 5 = 45. - Payments & pricing 60 (checked 2026-11-11): Model reading for gemini-decision-1 on the Gemini API's Decisions endpoint. Platform facts are the Gemini API listing's (gemini-api, re-read 1 November), carried over as RULES.md allows for a model on an already graded platform. No machine payment protocol (0). The pricing page lists $0.10 per million input tokens on the paid tier for every modality and no output charge, without a login (20). Free of charge on the free tier (20). A Google account and an AI Studio key come first (0). 0 + 20 + 20 + 0 = 40. Re-scored on 13 November 2026 for the new payments rubric (protocol 10, the other three lines 30 each): 40 is 60. - Task success: Pending. Task success needs the category task suites run through each tool, which haven't run yet, so this run doesn't score it. Its weight is shared across the assessed categories until then. A data provider's data-quality score is published on its listing now and becomes half of this category when it's scored. - Maintenance & community 79 (checked 2026-11-11): Model reading for gemini-decision-1 on the Gemini API's Decisions endpoint. Platform facts are the Gemini API listing's (gemini-api, re-read 1 November), carried over as RULES.md allows for a model on an already graded platform. Released on 11 November 2026, the day of this check (30). Deprecations with earliest dates and no stated minimum notice (4 of 12). Shutdowns in the last 90 days kept to their table (4 of 8). Dated changelogs: google-genai 3.2.0's entry adds the Decisions API; the platform changelog wasn't re-read today (11 of 15). SDK replies not sampled (5 of 10). google-genai 3.2.0 tagged the same day with `client.decisions.create`; the JavaScript SDK is per Google's post (15). Runtimes stated on the platform (10). 30 + 4 + 4 + 11 + 5 + 15 + 10 = 79. The model is hours old, so these lines are the platform's habits more than this model's record. - Transparency & trust 70 (checked 2026-11-11): Model reading for gemini-decision-1 on the Gemini API's Decisions endpoint. Platform facts are the Gemini API listing's (gemini-api, re-read 1 November), carried over as RULES.md allows for a model on an already graded platform. Closed service with clear terms, SDKs Apache-2.0 (15). The pricing page states that free-tier content is used to improve products and paid-tier content isn't; abuse retention has no number (15 of 30). Deprecations table; the model page names no deprecation for this model (15 of 20). Data may be cached anywhere Google has facilities; no subprocessor list checked (5 of 20). Every benchmark, latency and cost comparison is Google's own, and the post gives charts without scores in its text. 15 + 15 + 15 + 5 = 50. Fix list, everything this grade says the listing lacks, the biggest gain first (16 items). What it covers is at https://www.anchorterminal.com/fixes/gemini-decision-1.md (JSON https://www.anchorterminal.com/fixes/gemini-decision-1.json). The whole list for a coding agent comes from `POST https://www.anchorterminal.com/api/v1/fix-list` with `{"listing": "gemini-decision-1", "plan": "read"}`, free while the beta runs ### 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. ### Sources - Google's announcement: model, question types, limits, pricing, latency and benchmark claims, availability: (seen 2026-11-11) - google-genai 3.2.0 changelog, Decisions API added: (seen 2026-11-11) - google-genai Decisions request and response types (cloned): (seen 2026-11-11) - Gemini API docs index for agents: (seen 2026-11-11) - API versions, what v1beta means: (seen 2026-11-11) - Decisions API guide: fields, limits, what is unsupported, errors: (seen 2026-11-11) - Gemini Decision model page: limits and unsupported capabilities: (seen 2026-11-11) - Gemini API pricing, Gemini Decision section: (seen 2026-11-11) - Gemini API rate limits and usage tiers (no Decision row): (seen 2026-11-11) ## Score history Every move of a score since the listing was graded, newest first, with its cause.

Google's story page (read 28 October 2026) says Larry Page and Sergey Brin started Google; their current roles rest on Wikipedia, as abc.xyz answered the top stream with a bot check. Sundar Pichai's role is from Google's company information page and Demis Hassabis's from Google DeepMind's about page, both read today. Listing people now rest on Google's own pages (the blog.google author page, the Google Cloud Next 2026 speaker page, the Google Developers Blog, the Google Maps Platform blog and the Firebase blog), and stay on their own listings only. The Lyria RealTime authors stay as they are, on the arXiv paper's author list. - Google: LinkedIn https://www.linkedin.com/company/google X https://x.com/Google ### Ownership and investors - Ownership: Part of Alphabet Inc. ### Getting support - No support route found yet. - Sources: https://www.linkedin.com/in/alicevik/, https://www.linkedin.com/feed/update/urn:li:activity:7462720959725334528/, https://www.linkedin.com/in/tulsee-doshi/, https://about.google/intl/ALL_en/our-story/, https://www.linkedin.com/company/google, https://x.com/Google ## Live (updated 2026-11-13 16:15 UTC) - security.txt: valid, expires 2030-04-01T00:00:00z - Always current: https://www.anchorterminal.com/api/v1/live/gemini-decision-1.json ## 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. Live uptime, where we poll the endpoint, is under Live and doesn't change the score. ## Prices | Item | Price | Unit | Note | | --- | --- | --- | --- | | Gemini Decision 1 input | $0.10 | per 1M tokens | Text, image, audio, video and PDF. Shared input billed once per request | | Gemini Decision 1 output | free | per 1M tokens | No output tokens are generated | Across all listings: https://www.anchorterminal.com/prices/index.md ## 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) 1. Call POST /v1beta/decisions or `client.decisions.create` (SDK 3.2 or later), not generateContent or the Interactions API 2. Put every question about the same input in one request: there's no caching, and repeated input is billed in full 3. 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 4. Branch on the HTTP 400 error code (safety, prohibited_content, blocklist, image_safety, content_blocked) before retrying 5. Keep question keys to [A-Za-z0-9_-] and 64 characters, and options or levels between 2 and 255 ## Connect First request: ```bash curl -X POST "https://generativelanguage.googleapis.com/v1beta/decisions" \ -H "x-goog-api-key: $GEMINI_API_KEY" -H "content-type: application/json" \ -d '{"model":"models/gemini-decision-1","input":"The blue mug I ordered arrived cracked.","questions":{"damaged":{"type":"noul","instructions":"Did the item arrive damaged?"},"team":{"type":"choice","instructions":"Which team handles this?","criteria":{"returns":"Damaged or wrong items","billing":"Charges and refunds"}}}}' ``` ## Similar tools Ranked by shared capabilities, then score.

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}/decisions` (source: ) - 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: ) ## In Scuttlebutt - What the chat says about it, newest first: https://www.anchorterminal.com/api/v1/chat.json?listing=gemini-decision-1.
