Check the current provider rate
Jev may be available through more than one provider surface. Treat each provider page as the source of truth for its current model ID, billing unit, limits, and included usage because those details can change.
Measure decisions, not requests
A cheap request can still be expensive if many outputs are uncertain, invalid, or retried. Track input usage, latency, confidence, error rate, and the percentage of results that enter fallback.
Include the human review path
If low-confidence cases go to a reviewer, that work belongs in the unit economics. A useful comparison reports cost per accepted automated decision and cost per reviewed decision separately.
Do not estimate missing usage fields
When a provider omits usage or pricing data, mark it unavailable and reconcile with provider billing. Invented precision makes model comparisons less trustworthy.
Where Jev sits among decision model APIs (October 2026)
Jev is no longer the only published price in the category. Hosted, input-only, output free: Jev $0.042 per million input tokens; Perplexity Decisions API $0.02 (halved from its $0.04 launch rate, verified 2026-10-07); OpenAI’s Luna-based Decisions API $0.10 while in public beta — that rate is published on OpenAI’s developer guide page, and its main pricing page still lists no separate Decisions line, so re-check both before you budget. The open-weight routes (Cloudflare Clef, Liquid D1, Laya, the OpenJev family) carry no API price at all: the marginal cost is the GPU you run them on. The six-vendor comparison lives on our decision model API hub; the calculator below keeps Jev against general-purpose LLMs.
