A curated awesome list of public projects and practices built on Jev, TypeSafe AI's System One model for typed decisions.
This README is the homepage aggregate of the current category files, so the latest accepted entries are visible here without drilling into subpages.
Jev is not a chat model. It takes unstructured state plus a typed question and returns a typed decision — a choice, a score, or a boolean, each with a confidence. That makes it a drop-in decision layer for software: classification, routing, rubric scoring, verification, and agent guardrails. This list tracks who is actually building with it, and which patterns transfer across industries.
The repository treats all categories equally — each entry lives in exactly one category, chosen by its direct Jev application domain. A dedicated Related Practices / Discussions category captures credible public practice signals — X threads, Reddit discussions, and interviews — that describe real Jev usage even when no strong standalone case page exists yet.
Warning
A listing is not an endorsement. This project applies inclusion rules only — public, citable, genuinely uses Jev for a typed decision, one-sentence summary. It does not review code quality, security, maturity, or whether a project runs at all.
Treat same-day bulk submissions with particular care. Several repositories published together by one author, sharing a scaffold and a thin commit history, can satisfy every inclusion rule and still be unproven. Volume is not evidence of quality. See Curation is not endorsement for a checklist to run before adopting anything here.
Most Jev discussion is scattered across launch threads, model-gateway listings, and one-off prototypes. This list answers two practical questions quickly:
- Where is Jev already making real decisions in production workflows?
- Which decision patterns transfer across industries?
This is not a comprehensive database. It is a high-signal, fast-scanning field guide.
