The shortest path from messy input to a typed decision
Jev keeps the state, the questions, and the decision types visible so you can inspect what the model is deciding.
State
The facts your software already has.
Question
The decision you want Jev to make.
Typed answer
Choice, score, or noul with confidence.
learn / build / share
Learn the vocabulary before you ship it
Short explanations, working examples, and the surrounding ecosystem in one place.
resources / ecosystem
A living resource library
Official docs first, then useful community projects, SDKs, MCP servers, integrations, and experiments.

recipes / use cases
Start from a decision you already need
Recipes turn a use case into a schema, a runnable example, and code you can take home.
benchmarks / methodology
See what the decision is good at
Small, transparent benchmark runs with the dataset version, provider, model, latency, and failure cases exposed.
BenchmarksThis site publishes the evaluation method before claiming measured results. F1, latency, and sample counts will be added only with a real dataset and reproducible run record.
These are directional experiments, not universal model rankings.
next decision
Begin with one decision
Use the glossary, browse the resources, or run the sample. Jev 101 is built for the first afternoon, not the last mile.
