SimpleJev's LoRA adapters and pointer head that turn an open model into a typed-decision model: given a state, a question and the options, it returns a probability for every option without generating text. This entry is the Qwen3.8-27B release; the others are linked.
Uprelic's hosted decision API, run on GPUs in Paris. Answers noul, choice and score questions about text, JSON and up to 8 images, with a probability for every option and no generated text, on the same request shape as Jev. No weights; base model and size not disclosed.

Questions
What is the difference between jevany and strom?
jevany is from SimpleJev and strom from Uprelic. jevany has open weights you can download and run; strom is only available as a hosted API. Both answer choice, score and noul questions. Only strom answers classify and route. jevany is licensed apache-2.0; strom, proprietary.
Which is more accurate, jevany or strom?
They report on different suites — jevany 86.0% on SimpleJev Transfer suite (1,046 decisions from seven cross-domain datasets plus robustness slices; the maker's own), strom 87.0% on JevBench public set (231 items), the maker's production run of Strom 1.0.7 on 1 Oct 2026 (Open-Jev harness format) — so the numbers do not rank them. Test both on your own labelled examples.
Which is cheaper, jevany or strom?
jevany: Free (open weights). strom: $0.042 / $0 per 1M. Open weights cost nothing per call beyond your own hardware.
Can I run jevany or strom locally?
jevany yes — systemone pull simplejev/jevany downloads its weights. The other is only served as a hosted API.
