## Summary

Liquid AI released **d1**, a decision model designed for structured choices like classification, ticket routing, and moderation. Unlike text-generating models, d1 returns calibrated probabilities across predefined outcomes in a single API call, with no generated tokens billed. It supports three primitives—**Noul** (yes/no with probability), **Choice** (top pick from a set), and **Score** (ordered rubric ratings)—and evaluates all questions against the same input state in one round trip.

The model is available today via Liquid’s hosted API under **d1:free**, with no self-hosting options. Liquid’s migration guide advises using d1 for tasks with fixed answer sets (e.g., spam detection, urgency triage) and reserving LLMs for generation or multi-step reasoning. A demo shows d1 powering a real-time road-decision game, outperforming a competitor model in consistency. The company highlights benefits like predictable latency, no schema errors, and reduced round trips compared to LLMs.

## Key points

- d1 returns typed decisions with calibrated probabilities and zero output tokens, billed only for input
- Supports three primitives: Noul (yes/no), Choice (top pick), and Score (ordered ratings) in one call
- Deployable now via Liquid’s API as **d1:free**; no self-hosted weights or training options

## Why it matters

Decision models like d1 cut costs and latency for structured tasks, replacing LLMs in classification, routing, and moderation without generation overhead. This could reduce operational costs for teams handling high-volume, rule-bound workflows.
