Model board / Jev 1.13

Verified 2026-09-24 against the pages listed below. Prices are USD per 1M tokens, list rate — no committed-use, enterprise or volume discount.

billed per input token only — output is free, because a System One model generates no text. $42 per billion input tokens. Not comparable per token with the language-model rows above: it answers typed questions, it does not write

64K per request for state plus all questions; 32K for state plus the single longest question. Vercel's AI Gateway lists 32,000

no caching or batch discount documented

Watch out

Early access with limits that "can change without notice", English-first, text only, and no fine-tuning. TypeSafe's speed and cost multiples are measured on its own workflows. Also served through Vercel's and Netlify's AI gateways

What we would use it for

Routing, triage, guardrails and rubric scoring where code needs a typed answer and a calibrated probability, not prose

What this has cost, week by week

Output price at each refresh since 2026-09-24. A vendor change is the provider changing its price. Our correction means this board changed what it prints and the provider's charge did not move — the two are never merged, because publishing the second as the first would be a price rise that never happened.

Nothing has moved since we started tracking it.

No number on this page was written that was not read from one of those pages on 2026-09-24. If one is wrong, send us the source URL and it is corrected in the next weekly refresh, with a changelog line saying what was wrong — contact@naderu.com.

Jobs this is one of our picks for

• Typed decisions (Jev-class) — State in, a calibrated choice out — no text generated (typed-decisions)
