Open AI Decisions API is coming soon.

LIQUID AI / VERCEL AI GATEWAY

Liquid d1

Liquid AI's decision model for classification, routing and scoring. Send one shared state with typed questions and get structured answers with probabilities instead of generated prose.

Vercel AI Gateway currently lists Liquid d1 as free (checked September 30, 2026). This site charges its minimum 1 credit for each successful request.

Uses the TypeSafe decision contract

Liquid d1 is available through Vercel AI Gateway's TypeSafe-compatible endpoint. It accepts the same state and typed questions as Jev and returns answers keyed by the same question IDs. The existing playground can switch between the two models without changing the input format.

STATE → DECISION

Three structured answer types

Ask a yes/no question (noul), choose from named options, or score against an ordered scale. Answers include probabilities for your application to interpret; d1 does not generate explanatory prose.

Vercel lists a 32,000-token context and no generated output tokens. This site's shared workbench accepts text or JSON state, up to 8 questions and 32 KiB per request. Check the live model page for current availability and price.

Compare Liquid d1 and Jev in the same playground

This page opens the existing Jev workbench with Liquid d1 selected. Keep the state and questions fixed, then switch the model to compare the returned choices, scores and probabilities. The browser draft is saved separately from the main playground.

Call through Vercel AI Gateway

Use a site API key with Jev AI Model's /v1/systemone endpoint. Select liquid/d1 as the model. The server forwards the request to Vercel AI Gateway using VERCEL_AI_GATEWAY_API_KEY; the Gateway key stays on the server.

The public Vercel listing currently shows $0 input and output cost. At a zero upstream price, a 50% gross-margin token rate has no nonzero cost base: the token rate is 0 credits per million and this site applies its 1-credit successful-request minimum. If Vercel changes the price, recalculate the rate from the paid upstream cost before updating billing.

// Server-side JavaScript (Node 20+ or Bun). Set JEV_API_KEY.
const response = await fetch("https://jevaimodel.net/v1/systemone", {
  method: "POST",

How the 50% margin calculation works

Credits are worth $0.0001 each at the listed pack rate. For a nonzero upstream cost, a 50% gross margin requires a selling price equal to twice that cost: credits per million = upstream dollars per million × 20,000. For reference, Jev at $0.042 per million input tokens would require 840 credits per million for 50%; its current 600-credit rate corresponds to a 30% gross margin. Liquid d1's current $0 listing instead bills at the 1-credit request minimum.
