Automated README summary
Automatically summarized from the README on 30 Sept 2026; not a run by jevbooks. Run instructions and author-reported outcomes still need verification.
What it is
A curated catalog of open-source projects that use Jev, TypeSafe AI's System One model. For developers seeking real-world examples of Jev for decision-making, routing, and action selection.
How it uses Jev
Projects use Jev to make decisions such as picking browser actions, classifying rows, scoring files, or judging tool calls. Jev returns probabilities for Choice, Score, or Noul questions based on provided state, and code uses these to determine next steps.
Primitives:choicescorenoul
Technique worth stealing
Using Jev for fast, calibrated decisions in agent loops instead of text generation.
Model judgments from README excerpts
Project signals use repository metadata, an existing summary and the first 700 README characters, not the full project. “Not found” means not detected in that material; it does not establish absence. These are the original judgments with recorded models and dates, not source audits or run results.

Evidence
These signals use repository metadata, an existing summary and at most 700 cleaned README characters. ≥ 0.60 means reported in that excerpt; ≤ 0.40 means not found there. The middle band is inconclusive. None is a source-code audit or a test result. The runnable-tool question excludes research experiments; the recommendation question asks for a learning shortlist, not a quality verdict.
