Highlights
- 10 points and 4 comments on 23 September 2026.
- The author describes Jevper as the Jev interface pointed at a model you already have, so classification can use that model's reasoning.
- khimaros replies with verdict, a llama-server wrapper that finishes a decision in one forward pass from logprobs.
Watch out
A short thread. Verdict is already a separate entry. This does not add the Jevper repo.
Questions about this entry
Short answers drawn from the linked project or page.
Just the interface. The author describes it as the Jev interface pointed at whatever model you already have, so judgment quality is whatever sits behind your OpenAI-compatible endpoint. No benchmark appears in the thread.
The author's answer is that it is an alternative to the hosted route and a way to take advantage of an LLM's reasoning for the classification. The thread offers no measurement of whether that reasoning helps or hurts the labels it produces.
For the closest sibling, yes. A commenter points at verdict, a llama-server wrapper that takes advantage of logprob output and completes a decision in a single forward pass, which implies the server has to return them.
No numbers appear anywhere in the thread, which is four comments long. Commenters mostly post their own equivalents, including a router serving several decision-style models built on Mercury and Gemma, one of which takes image input.
czl_my's Show HN for the Jev interface pointed at any OpenAI-compatible model. It drew 10 points and 4 comments on 23 September 2026.
khimaros pointed to verdict, a llama-server wrapper that completes a decision in one forward pass from logprobs, and ljlolel mentioned router-hosted decision models including mev based on Mercury, gemmev based on Gemma, zev and lev, one of which takes image input.
jgilias asked 'but why', and the author answered that it is an alternative to Jev and a way to take advantage of the LLM's reasoning for the classification.

The typed-answer shape removes a category of data risk, not all of it. Zero data retention per surface, the legal set to read, and the controls that remain yours to run.
