Three 4B decision models with per-option probabilities and Jev API.

Automated README summary

Automatically summarized from the README on 16 Oct 2026; not a run by jevbooks. Run instructions and author-reported outcomes still need verification.

What it is

JevAlt provides three 4B open-weights language models for English, Turkish, and German that choose between options and return a probability for each, for routing, policy checks, and typed decisions on your own hardware.

How it uses Jev

JevAlt implements the Jev API (POST /v1/systemone). Given a state and typed questions (choice, score, noul), the models return calibrated probabilities for each option. The server allows existing Jev clients to use these models for decisions.

Primitives:choicescorenoul

Technique worth stealing

Fine-tune Intern-Decision-4B with LoRA to output per-option probabilities for typed decisions.

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.
