Hands-on playground for judging Hugging Face models against devices with JEV.

Evaluation & Benchmarking0.95Runner-up: Calibration & Research
Automated README summary

Automatically summarized from the README on 20 Oct 2026; not a run by jevbooks. Run instructions and author-reported outcomes still need verification.

What it is

A small educational app that lets you pick a Hugging Face model, a use case, and a device, then have JEV judge suitability two ways: from a text description and from numeric data, compared with code-calculated results.

How it uses Jev

JEV judges whether a model fits a device and use case. It receives either a text description or numeric data (capacity and speed) as state, and returns a judgment that the app displays alongside the code-calculated result for comparison.

Primitives:choice

Technique worth stealing

Comparing JEV's judgment from text-only versus numeric input against a code-calculated baseline.

Try it

In local/, run npm install and npm start, then open http://localhost:3210.

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.
