Automated README summary
Automatically summarized from the README on 28 Sept 2026; not a run by jevbooks. Run instructions and author-reported outcomes still need verification.
What it is
JevGPT is a ChatGPT-style chat app that generates replies one word at a time using TypeSafe's Jev System One model, which returns calibrated probabilities for multiple-choice options.
How it uses Jev
Jev answers 15 questions per word: which word group comes next, and which word within each group. Probabilities multiply into a distribution over ~1,800 words plus END. Optionally, Jev re-ranks the top 12 full continuations before sampling.
Primitives:choice
Technique worth stealing
Split a large vocabulary into groups under 255 options, then multiply group and within-group probabilities.
Try it
npm install && npm run dev, open localhost:3000, enter TypeSafe API key.
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.
