# Decisions Fast

> Parallel Decisions Fast is a web-grounded Decisions model: send `state` (text or JSON) plus up to 100 typed `questions` (noul / choice / score) and get structured answers with per-question refusals and request-level citations after live web research — not generated chat text. Each question may use at most 32,000 estimated input tokens including the shared state. Call POST /api/v1/decisions (POST /api/v1/systemone is the same handler).

### Strengths [2,1]

- Answers are grounded in the live web, with a probability for each answer and citations for the whole response
- Up to 100 related questions share one retrieval and are billed as one request on Parallel's API
- Returns a refusal instead of a guess when the web has no answer

### Known limits [2]

- Closed questions only: open-ended research or long-form output belongs to the Task API
- Not for use when the answer must come only from what the caller supplies; it researches the live web

### Use cases [1]

- CRM enrichment across thousands of company records
- Eligibility checks against current program or insurance rules, with web evidence for review
- Agent guardrails: check whether a claim is still current before acting

### API notes [1,3]

- System One envelope: state plus named questions of type noul, choice, or score
- Noul returns a probability from 0 to 1; choice takes 2 to 255 options; score rates 2 to 10 ordered levels
- Each question including the shared state may use at most 32,000 estimated input tokens
- Up to 100 questions per request share one retrieval; citations carry url, excerpts, and optional title
