Benchmark: Jev decision models vs an LLM on crypto question routing.

Classification & Routing0.71Runner-up: Evaluation & BenchmarkingFunnelCheck-up
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 small reproducible benchmark comparing single-pass decision models (Jev, Kev-4B) against Claude Haiku 5.5 on routing and guardrail decisions for crypto market questions, measuring quality, calibration, latency and cost.

How it uses Jev

Jev answers two decision nodes on a user question: a Router (14 options: 13 data-tool areas plus unsupported) and a Guardrail (allow, advice, off_topic). It returns a probability per option from one prefill pass; the benchmark scores the selected option and calibration.

Primitives:choice

Technique worth stealing

Compare decision models to an LLM on the same items and options, scoring accuracy, Brier calibration, latency and cost.

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.
