Can a small local LLM replace Jev as a decision model?

Automated README summary

Automatically summarized from the README on 13 Oct 2026; not a run by jevbooks. Run instructions and author-reported outcomes still need verification.

What it is

An experiment comparing a general local LLM (Qwen) read as a decision model via label logprobs against TypeSafe's Jev on 310 synthetic AIOps alerts, with three decisions per alert: category, priority, and page a human.

How it uses Jev

Jev answers the same three decisions (category, priority, page a human) on each alert's state, using the same question wording as Qwen from src/schema.py. Its output shape (choice + confidence + probabilities) is scored identically to Qwen's by src/score.py.

Primitives:choicescore

Technique worth stealing

Read a general LLM as a decision model by renormalising label-token logprobs over allowed labels in one forward pass.

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.
