Automated README summary
Automatically summarized from the README on 3 Nov 2026; not a run by jevbooks. Run instructions and author-reported outcomes still need verification.
What it is
A curated awesome-list of System One models — AI models that make fast, structured decisions rather than generating text — covering Jev from TypeSafe, open and hosted alternatives, plus agents, tools, SDKs and benchmarks for developers choosing or building with them.
How it uses Jev
The README describes Jev as the original System One model: you pass state plus typed questions and it returns a choice, a score, or a yes/no probability, with nothing to parse. It does not document specific Jev API calls, code examples, or how results are consumed in application code.
Primitives:choicescorenoul
Technique worth stealing
Framing decision models as state-in, typed-answers-out (choice/score/probability) instead of text generation, so no parsing is needed.
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.
