The same decision workflow, with a different billing path
Jev and Liquid d1 both evaluate shared state against typed questions. Their request and response semantics are compatible, while their gateway formats and current prices differ.
This app currently calls Jev through OpenRouter and Liquid d1 through Vercel AI Gateway. The shared playground can run the same state and questions against either model after a small server-side adapter maps Noul to boolean and normalizes usage.
Compare the operating details
Compatible decisions, provider-specific wire formats
Use the same examples to compare behavior. This page keeps the price snapshot separate from model-quality claims, which still need a labeled evaluation set.
50% gross-margin credit rate
Jev
840 / 1M input tokens
Liquid d1
0 / 1M tokens + 1 / request minimum
At $0.0001 per credit, a 50% margin charges twice upstream cost. The zero-price d1 rate therefore computes to zero before the per-request minimum.
Decision output
Jev
Typed answers with probabilities
Liquid d1
Typed answers with probabilities
Both return boolean, choice, and score decisions. The adapter translates field names and token-usage casing; the Gateway response does not add a separate confidence field for Choice or Score.

01
You want to try d1 through the Vercel AI Gateway.
Use Liquid d1The site routes d1 to Vercel’s evaluation endpoint using the configured VERCEL_AI_GATEWAY_API_KEY.
02
Your existing app already calls Jev through OpenRouter.

A confidence threshold will trigger an action.
Evaluate before routingRun labeled examples through both models and compare false positives, false negatives, and calibration before you set production thresholds.
What changes when the provider changes?
The playground stays the same; server-side routing adapts each provider contract.
Jev · OpenRouter Decisions API
Noul, Choice, and Score
The current integration sends the shared state and Jev’s typed questions to OpenRouter, then bills input tokens at the configured app rate.
- Upstream input price is $0.042/M and output is $0/M.
- The current app rate is 600 credits/M, equal to $0.06/M or about 30% gross margin on model-token cost.
Liquid d1 · Vercel AI Gateway
Boolean, Choice, and Score
The gateway evaluation API accepts the same shared state and typed-decision workflow. This app maps its Noul question to boolean and converts the returned probability into the Jev playground answer shape.
- Vercel currently lists $0/M for both input and output, with a 32K context and 0 generated output tokens.
- The 50% gross-margin rate is 0 credits/M; successful calls still meet the existing one-credit minimum.
Request and response compatibility

Sources and calculation
Provider prices were checked on September 30, 2026. The 50% gross-margin target uses sell price = model cost ÷ (1 − 0.50), with $0.0001 per credit. Jev’s 840 credits/M is the target rate; the current app rate remains 600 credits/M. Liquid d1 is currently listed at $0/M, so its target token rate is 0 and the app minimum of 1 credit/request determines the actual charge. Because listed token cost is zero, that minimum yields more than a 50% margin on model-token cost alone; Gateway, payment, and serving costs are excluded.
