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.

🤖 tamaratran/fast-jev-compaction · ⭐7380 · TypeScript · 🔎 inferred · 16d · ⭐+2
📝 Summary
Claude Code plugin that replaces the compaction summary with Jev decisions: every tool call and result is scored in one fast request, stale ones are dropped or truncated, everything kept stays verbatim.
💡 Replaces a coding agent's context-compaction summary with a typed decision. A clean example of swapping one LLM call in an existing pipeline rather than rebuilding the pipeline.
