Best decision models for AI agents · All 241 decisions comparisons
Which one, for what
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.
Ahead on
- Maintenance & community, 79 against 68
Watch for
No context caching, Batch API, Flex or Priority: the guide says repeated input across requests counts in full
Best for Typed decisions with per-option probabilities over text, JSON, images, audio and PDFs, including on streaming state
Ahead on
- Reliability, 50 against 40
- Security & auth, 70 against 45
Also in its favour
- A hosted endpoint, with nothing to install
- Free to start without a card
Watch for
Standard context is 38,000 tokens. The 64k, 128k and 1M bands are held, and video is a preview

Security & auth RightNow System Zero +25
Gemini Decision 1 45
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.
RightNow System Zero 70
Read for a model API. Workspace API keys are named, shown once and revocable by their creator or an admin, with a leaked-key procedure. They have no scopes, and the stream refuses credentials in the URL (20 of 30). The privacy policy and terms say content and answers are never used to train any model and request content isn't logged. Answers are kept for up to 24 hours only when a request sends an Idempotency-Key (18 of 20). Requests whose content reads as instructions to the model are refused with 422 injection_suspected, the terms warn that hidden instructions in documents or images can change answers, and the Danger zone page says the guard isn't qualified for every input size (12 of 15). The console lists recent requests by ID, status and error code without content, and usage separates answered, replayed and failed calls. We found no exportable audit log (12 of 15). security.txt is valid until 20 September 2027, and the SDK repository's SECURITY.md takes private reports. trust.rightnowai.co shows SOC 2 Type 2 as compliant with no public documents, and the blog and contact footers label it 'RunInfra: SOC 2 Type 2'. No report was reviewed and no bug bounty was found (8 of 20).
Maintenance & community Gemini Decision 1 +11
Gemini Decision 1 79
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.
RightNow System Zero 68
Read for a model. Launched on 15 October 2026, with price card G and SDK 0.4.2 on 27 October and the models and rate-limit pages updated on 31 October (30). Six SDK releases on npm and PyPI from 20 to 27 October and two dated release-note entries. Pinned model IDs are said to have a retirement notice policy, but no notice period is stated (12 of 20). Public release notes, Discord and a contact form, and the SDK's SECURITY.md aims to acknowledge reports within five business days. We didn't read Discord or the GitHub issues (7 of 15). Official TypeScript and Python SDKs under Apache-2.0 at 0.4.2. The docs say 0.4.2's request contract predates the served API spec for long context (13 of 15). npm versions from 0.1.0 were published by GitHub Actions and the Python package bounds its dependencies. GitHub's API wasn't reachable from this session, so CI results went unread (6 of 10).
Reliability RightNow System Zero +10
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.
RightNow System Zero 50
Scored as a hosted model API, as for Celeris-1 Decision and Clef. The docs, footer and privacy policy point to a public status page at status.rightnowai.co, but its robots.txt disallows every path (re-read on 1 November), so its components and history went unread (10 of 20, a judgement call). No readable incident history (5). Limits are published with numbers, 600 requests a minute per key, 16 calls in flight and 100,000 model calls a day per workspace, and 5,000,000 decisions a UTC month (15). 429 and 503 refusals carry Retry-After and Retry-After-Ms, every error carries a retryable flag mirrored in x-should-retry, and decide takes an Idempotency-Key (15). The terms say no service level agreement applies without a signed agreement (0). Text decisions launched on 15 October 2026 without a beta label, but video is a preview, the 64k, 128k and 1M bands are held, and the support page says availability counting changes 'at public launch' (5 of 10).

How the scores have moved
Verdicts
Gemini Decision 1
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.
RightNow System Zero
A well-documented decision API with an OpenAPI file, idempotent retries, a detailed error catalogue, streaming over WebSocket and published per-unit prices with USD 5 of starting credit. Standard context is 38,000 tokens; the 64k, 128k and 1M bands are held and video is a preview. The latency and benchmark figures are RightNow's own, and several of its pages disagree.
Before you call either
Gemini Decision 1
- 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
RightNow System Zero
- Send audio only as inline 16,000 Hz WAV. The FLAC, MP3, OGG and MP4 audio named on the blog are refused with media_unsupported.
- Keep state under 38,000 tokens. Long-context requests return 404 long_context_not_available, which never succeeds on retry.
- Reuse the same Idempotency-Key and body on retries, and stop when error.retryable or x-should-retry is false.
- Check every entry in answers even on HTTP 200, since one question can be refused while the others are answered.
- Treat probabilities as uncalibrated while calibrated is false, and pin system-zero-2.0.0 when answers must not move with the alias.
