Jev
Start hereEarly access · $0.042 / MTok input · output free. Waitlist at typesafe.ai. No public Free Forever.
Typed decisions from TypeSafe — noul, choice, score. Code branches. No prose to parse.
Agent: GET /api/catalog/tools/jev
Jev is TypeSafe AI’s System One model. Not chat. Not a writing seat. You send state plus typed questions; you get noul, choice, or score with probabilities your agent or code can branch on.
Use it where Skillrails already runs decision desks: support triage, refund recommendations, hire screens, research claim checks. Desktop agents draft prose. ClickUp holds the board. Resend/Email only after yes. Jev sits in the middle as the smart if. Early access. Join at typesafe.ai; keys at console.typesafe.ai after invite. Public price: **$0.042 per million input tokens**, output free (docs.typesafe.ai/models, fetched 2026-09-20). No public Free Forever plan found. Alternate path: Vercel AI Gateway model `typesafe-ai/jev` at the same listed input rate — still not Free Forever.

Use cases
You need a decision, not a paragraph
Jev (TypeSafe System One) returns noul / choice / score with probabilities. Grokbot and chat models write. Jev decides. Do not blur.
Agent drafts the question map. Side effects stay gated
State + questions in one call. Thresholds and actions live in code or the desk agent. Refunds, rejects, sends, kills — still need your yes.
Wire decisions into desks you already run
Support triage, refund grant/deny score, hire screen rubrics, research claim checks. ClickUp holds rows. Jev scores. You act.
Access is early — price is public, Free Forever is not
Waitlist / console keys at TypeSafe. Also on Vercel AI Gateway as typesafe-ai/jev at the same published input rate. Do not invent starter credits.
Decide in types. Act in code.
Jev scores. You still own the side effect. Early access — price is public.
- Decisions ≠ text gen — honest sibling to Grokbot
- Confidence gates: act / review / human
- No silent refund, reject, or send
