Automated README summary
Automatically summarized from the README on 13 Oct 2026; not a run by jevbooks. Run instructions and author-reported outcomes still need verification.
What it is
An independent, reproducible benchmark of TypeSafe's Jev against open, CPU-only alternatives. It measures classification/routing decisions across six stacks on four public datasets, publishing all raw results and per-item predictions.
How it uses Jev
Jev is called through Cloudflare Workers AI (typesafe/jev) with a state and typed questions whose options are supplied at request time. It returns a choice with calibrated probabilities. The benchmark compares its accuracy, latency, and cost against open CPU-only stacks.

Technique worth stealing
Enriched option descriptions help bi-encoders but hurt cross-encoders; verbaliser design is a per-architecture tuning knob.

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.
