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.

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
400 / 1M input tokens; platform charges 600
At $0.0001 per credit, a hypothetical 50% margin gives 400 credits/M for d1. The actual platform rate remains 600 credits/M, with a 1-credit minimum per successful request.
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.
Keep Jev in the comparisonThe current Jev integration remains available; choose either model in the shared workbench without changing the question editor.
03

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 $0.02/M input, free output, a 65,536-token context and 0 generated output tokens.
- The platform charges 600 credits/M of actual input usage, with a one-credit minimum per successful request.

Sources and calculation
Liquid d1 pricing was checked on October 19, 2026: $0.02/M input and free output on Vercel AI Gateway. The hypothetical 50% gross-margin calculation gives 400 credits/M for d1 and 840 credits/M for Jev at $0.042/M upstream. Actual platform rates remain 600 credits/M for both, rounded up to at least 1 credit per successful request. At $0.0001 per credit, d1 has about a 66.7% inference margin before Gateway, payment and serving costs.
