Automated README summary
Automatically summarized from the README on 19 Oct 2026; not a run by jevbooks. Run instructions and author-reported outcomes still need verification.
What it is
Von is an open-source System One decision model for developers who need fast, local typed-question inference over JSON or text state, positioned as a drop-in replacement for TypeSafe Jev. It is now archived and unmaintained.
How it uses Jev
Von answers Choice (pick one of K described options with a probability over all), Noul (probability a condition holds) and Score (calibrated ordinal position) over a state, using one forward pass of a 395M ModernBERT encoder with no token generation. Results are returned as choice/confidence/probabilities, noul, or score fields.
Primitives:choicescorenoul
Technique worth stealing
Answer typed questions with calibrated probabilities from a single encoder forward pass instead of generating tokens.
Try it
pip install von-sdk, then call von.decide / von.judge / von.rate, or run von serve for the /v1/systemone endpoint.
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.
