Jev-compatible API endpoint using open models and prefill-only inference.

Automated README summary

Automatically summarized from the README on 1 Oct 2026; not a run by jevbooks. Run instructions and author-reported outcomes still need verification.

What it is

A server implementing the TypeSafe/Jev HTTP API with Qwen3.6-35B-A3B on SGLang. It provides Noul, Choice, and Score evaluations for developers needing a Jev-compatible endpoint.

How it uses Jev

Jev makes decisions on a given state and typed questions (Choice, Score, Noul). The state is rendered with the model's chat template, and each question is tokenized as a suffix. The server performs one-token prefill calls to read label logprobs, renormalizes them, and returns probabilities.

Primitives:choicescorenoul

Technique worth stealing

Prefill-only inference: one-token calls with token_ids_logprob for exact label readout, avoiding autoregressive generation.

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.
