Automated README summary

Automatically summarized from the README on 17 Oct 2026; not a run by jevbooks. Run instructions and author-reported outcomes still need verification.

What it is

jevos is a self-hosted C++ server that answers typed questions (yes/no, multiple choice, score) about a text and returns probabilities, using a 1B model on a laptop CPU. It targets developers wanting Jev's API without the cloud.

How it uses Jev

The server takes a state (text or object) and typed questions in Jev's /v1/systemone format. For each question it runs the model once per text and returns P(yes) for noul, the most probable option for choice, and the expected level for score, plus per-answer probabilities and confidence. Code uses these to route or decide.

Primitives:noulchoicescore

Technique worth stealing

Reuse Jev's wire format so existing SDK code works unchanged for yes/no questions.

Try it

Download release and model, run ./jev serve, then POST to /v1/systemone.

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.
