Every entry below was collected, filtered and re-checked by the pipeline in this repository. Numbers and timestamps come from the sources, not from a hand-written snapshot.

🔥 Picks of the moment — the top of each category

One entry per category, ranked by evidence grade and stars, recomputed on every update. A ranking, not an endorsement; every pick links through to its full card below. Projects that published a screenshot or a recording are preferred, so the strip stays visual.

What is Jev

Jev is TypeSafe AI's first System One model. It does not write prose. It takes a state plus questions whose answer space you define in advance, and returns typed values with probability distributions your code can branch on.

Shape state + typed questions → constrained answers + probabilities → your code
Primitives Choice (pick one of ≤255 options), Score (a rubric 2–10), Noul (a probabilistic yes/no)
Endpoint POST https://api.typesafe.ai/v1/systemone, model jev-1.13.0 / alias jev-latest
Good fits routing, triage, scoring, moderation, verification and low-latency gates inside a bounded workflow
Known limits counting is unreliable, multi-level indirection is weak, and official material names nine classes of jaggedness. Schema-valid output is not the same as a correct decision — calibrate on your own data.

How entries are graded

Most lists in this space assert inclusion. This one says how much it actually verified, then lets you filter accordingly.

Grade What it means
official Published by TypeSafe AI itself.
observed A public artifact that can be opened and read — real source, real configuration, or an explicit TypeSafe/Jev declaration in the repository name or topic.
inferred Matched on an ambiguous signal plus corroborating vocabulary, but not yet read line by line.
unverified Looks related, nothing independently confirmed. Listed for discovery only.

📝 Summary

Agent skills for building with TypeSafe's System One API

💡 The vendor's own agent skills. Because it is updated continuously, it is the closest thing to a specification of how TypeSafe intends Jev to be driven from an agent.

📝 Summary

Drop-in TypeSafeClient replacement backed by LLM APIs

💡 Drop-in replacement that backs the same interface with an ordinary LLM provider. This is the honest way to A/B a typed decision against a prompt, on your own data, before committing to either.
