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.\n- OpenAI Decisions API (87): Read for a model API, on the lines used for Jev. Project API keys, with the access-control guide saying a key carries its own permissions that are checked against the caller's project role, service-account keys created through the Administration API with a documented rotation procedure, and workload identity federation with short-lived tokens. Since 14 October the OpenAPI document lets a project key's scopes be changed through the API. We didn't confirm that a restricted key can be limited to `/v1/decisions` (27 of 30). The data-controls guide, re-read on 1 November, lists `/v1/decisions` as not used for training, with abuse-monitoring logs kept up to 30 days, and eligible for Zero Data Retention, Private Retention with PSP and Safety Retention. The column that read pending confirmation on 17 October now reads yes. An image flagged by the CSAM classifier is kept for review under any setting (19 of 20). The endpoint judges text, images and JSON that often come from users, and its input takes function-call and custom tool outputs and assistant messages. Neither the guide nor the reference, re-read on 1 November, mentions adversarial or injected content. The safety guide advises red-teaming and limiting input length, and requests accept a `safety_identifier` (6 of 15). Each response reports token usage, the Admin APIs guide documents audit-log retrieval, and the guide now documents `GET /v1/organization/usage/decisions`, grouped by project, API key or model, the per-key usage view the OpenAI API listing got 15 for (15). security.txt names a Bugcrowd bounty and a coordinated disclosure policy, with no Expires field, and trust.openai.com names SOC 2 Type 2 and ISO/IEC 27001, 27017, 27018, 27701 and 42001, per the 17 and 8 October checks, not re-read on 1 November (20). 27+19+6+15+20 = 87.\n\n### Reliability: OpenAI Decisions API +30\n\n- Gemini Decision 1 (40): 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.\n- OpenAI Decisions API (70): Read as a hosted model API. status.openai.com has a Decisions component under APIs, with data since 29 September (20). The endpoint was released on 6 October, so its public record is 26 days long on 1 November. The feed, read on 1 November, lists Decisions in one incident, the 21 October degraded performance across ChatGPT, Codex and the APIs, where the component was degraded from 02:26 to 02:48 UTC with most other API components, 22 minutes and minor. No other incident since release names it, and the API-wide incidents of 17 and 29 September predate the release. 26 days with one minor incident rather than 90 days stays at 15 of 30, the short-record reading excaliclaw got for 11 clean days. The GPT-6 Luna page, re-read on 1 November, lists 5,000 requests and 2,000,000 tokens a minute on the Build tier, 10,000 and 10,000,000 on Launch and 30,000 and 180,000,000 on Grow, but its endpoint table still doesn't list Decisions and the guide gives no limits of its own (10 of 15). The rate-limits guide, re-read on 1 November, says `Retry-After` may be present on 429 and 503 and the error table says to follow it and back off, and a decision has no side effects, so a retry is safe (15). No SLA covering the endpoint was found, and the Scale Tier page wasn't re-read (0). Generally available since 22 October 2026, per the changelog and the guide (10). 20+15+10+15+0+10 = 70.\n\n### Transparency \u0026 trust: OpenAI Decisions API +19\n\n- Gemini Decision 1 (70): 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.\n- OpenAI Decisions API (89): Closed service with Apache-2.0 SDKs and an MIT OpenAPI repository. The services agreement wasn't re-read on 1 November, so its terms stand per the OpenAI API listing's earlier check (15). The data-controls guide, re-read on 1 November, gives `/v1/decisions` its own row and section covering training, 30-day abuse logs, Zero Data Retention, Private Retention with PSP, the 24-hour prompt cache and HIPAA eligibility, with no column pending any more. The DPA, effective 1 January 2026, commits to return or deletion of customer data on termination, 30 days to object to a new subprocessor, and SCCs with the UK Addendum, and nothing in it conflicts with the guide, per the OpenAI API listing's 4 October check, not re-read on 1 November (openai.com answered 403). The same reading as the OpenAI API listing (30 of 30, was 28). The deprecations page gives dated notices and minimum notice periods for models, which now cover Decisions as a GA endpoint on a GA model. It names no policy for endpoints, and the one model is an alias without snapshots (18 of 20). The data-controls guide lists Decisions in every data-residency region for storage, with regional processing in the United States and Europe. The subprocessor list, updated 9 July 2026, names third-party subprocessors and OpenAI affiliates with processing countries for each and a form for notice of new ones, per the OpenAI API listing's 4 October check, not re-read on 1 November (openai.com answered 403). The same reading as the OpenAI API listing (20 of 20, was 16). 15+30+18+20 = 83.\n\n### Payments \u0026 pricing: Gemini Decision 1 +15\n\n- Gemini Decision 1 (60): 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.\n- OpenAI Decisions API (45): No x402, MPP or L402 in the guide or the pricing page, re-read on 1 November (0). Per-token price published without a login, $0.10 per million uncached input tokens with no output charge. Since general availability on 22 October cache reads and writes are charged at GPT-6 Luna's standard rates ($0.01 and $0.125 per million), where the beta charged neither (20). The rate-limits guide lists a Free tier capped at $100 a month in allowed countries, but the GPT-6 Luna page's rate-limit table still starts at Build, which needs $5 of credit, and the Decisions guide doesn't mention a free allowance, so half, as for the OpenAI API listing (10). A person signs up in a browser and creates a key (0). 0+20+10+0 = 30. Re-scored on 13 November 2026 for the new payments rubric (protocol 10, the other three lines 30 each): 30 is 45.\n\n### Schema \u0026 documentation: OpenAI Decisions API +11\n\n- Gemini Decision 1 (80): 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.\n- OpenAI Decisions API (91): OpenAI's OpenAPI 3.1 document (version 2.3.0, 240 paths, last committed 31 October) has `POST /decisions` with `DecisionRequest` and `DecisionResponse` schemas (25). llms.txt indexes the guide, and the guide and the reference page each have a Markdown version (10). The guide says which question type fits which job and when to use Structured Outputs or function calling instead. Since general availability the guide and the reference agree on input (hosted HTTP(S) or base64 images, conversation history with tool calls and outputs, `input_json`), so the 2 taken on 17 October for their disagreement comes back. No page of known limits for the model on this endpoint was found (16 of 20). Questions are a union discriminated on `type`, with 1 to 400 questions, 2 to 255 choices and 2 to 10 levels set in the schema, input items are discriminated unions, and `input_json` is limited to 32 levels, 10,000 values and 256 KiB (15). The guide has examples in curl, JavaScript, Python, Go, Java and Ruby with sample responses. The OpenAPI operation documents only the 200 response, and errors are covered by the general error-codes guide (12 of 15). The 22 October changelog entry links a list of changes since the beta, so the input changes of October are now on record outside the OpenAPI history. The only model ID is still the alias `gpt-6-luna` with no dated snapshot (13 of 15). 25+10+16+15+12+13 = 91.\n\n## Score by category\n\n| Category | Weight | Gemini Decision 1 | OpenAI Decisions API | Edge |\n| --- | --- | --- | --- | --- |\n| Reliability | 16% (20 this run) | 40 | 70 | OpenAI Decisions API +30 |\n| Performance | 10%, pending | pending | pending | not scored in this run |\n| Schema \u0026 documentation | 13% (16.2 this run) | 80 | 91 | OpenAI Decisions API +11 |\n| Agent ergonomics | 13% (16.2 this run) | 85 | 87 | OpenAI Decisions API +2 |\n| Security \u0026 auth | 14% (17.5 this run) | 45 | 87 | OpenAI Decisions API +42 |\n| Payments \u0026 pricing | 10% (12.5 this run) | 60 | 45 | Gemini Decision 1 +15 |\n| Task success | 10%, pending | pending | pending | not scored in this run |\n| Maintenance \u0026 community | 7% (8.8 this run) | 79 | 79 | even |\n| Transparency \u0026 trust | 7% (8.8 this run) | 70 | 89 | OpenAI Decisions API +19 |\n| Negative events | ≤15 | 0 | 0 | |\n| **Total** | | **63.2 · B** | **78.5 · A** | |\n\n## Facts side by side\n\n| Fact | Gemini Decision 1 | OpenAI Decisions API |\n| --- | --- | --- |\n| Kind | Model API | Model API |\n| Vendor | Google | OpenAI |\n| Hosted endpoint | no (local only) | `https://api.openai.com/v1/decisions` |\n| Transports | HTTP | HTTP |\n| Auth | API key | API key |\n| Pricing | Pay per use | Pay per use |\n| Price for decision models | free | $0.01 per 1M tokens |\n| x402 | no | no |\n| Licence | Closed model, used through the Gemini API's Decisions endpoint under Google's terms.

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.\n\n**OpenAI Decisions API.** Typed predicate, choice and score answers with probabilities, up to 400 questions a call, at $0.10 per million uncached input tokens with no output charge. Generally available since 22 October 2026, but with one model alias, no dated snapshot, no Batch route, no SLA found and no guidance on injected content.\n\n## Before you call either\n\n### Gemini Decision 1\n\n1. Call POST /v1beta/decisions or `client.decisions.create` (SDK 3.2 or later), not generateContent or the Interactions API\n2. Put every question about the same input in one request: there's no caching, and repeated input is billed in full\n3. 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\n4. Branch on the HTTP 400 error code (safety, prohibited_content, blocklist, image_safety, content_blocked) before retrying\n5. Keep question keys to [A-Za-z0-9_-] and 64 characters, and options or levels between 2 and 255\n\n### OpenAI Decisions API\n\n1. Put independent questions about one input in a single `questions` array, up to 400. Send a separate request when a question depends on an earlier answer\n2. Check each answer's `type` before reading it. A question can come back as `refusal` while the others in the same request are answered\n3. Keep shared evidence identical at the start of `input` to reuse the cache, and set `prompt_cache_options.mode` to explicit if one-off prefixes shouldn't incur cache writes\n4. Give a `choice` question a fallback value such as `other`, and set thresholds from your own labelled examples\n5. Use Python SDK 3.26.0 or JavaScript 7.30.0 or later, and follow `Retry-After` on 429 and 503\n\n## Tutorials\n\n- [Route an invoice question with OpenAI Decisions](https://www.anchorterminal.com/tutorials/openai-decisions-api/), for OpenAI Decisions API\n\n## Questions\n\n### Which is better for AI agents, Gemini Decision 1 or OpenAI Decisions API?\n\nOpenAI Decisions API scores 78.5 (A) on agent readiness against Gemini Decision 1's 63.2 (B), and leads in 5 of 7 scored categories.
