bev vs jevany

Q: Can I run bev or jevany locally?

Yes, both: systemone pull berget-ai/bev and systemone pull simplejev/jevany download the weights.

Berget AI: bev and SimpleJev: jevany, compared on what they decide, where they run, what they cost and what their publishers report.

The short version

Both have open weights you can download and run.
Both answer noul, choice and score questions.
bev is the smaller model, at 9.0B parameters to 27B.

Property	berget-ai/bev	simplejev/jevany
Summary	Berget AI's System One model for gating agent commands: a LoRA adapter and a fine-tuned joint schema head on Cloudflare's Clef-Flash that answer noul, choice and score questions over a state in one forward pass. Trained on Swedish and English operations decisions.	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.

Which is more accurate, bev or jevany?

They report on different suites — bev 97.0% on Berget held-out risk split (16,902 questions; same operations-traffic corpora as training), jevany 86.0% on SimpleJev Transfer suite (1,046 decisions from seven cross-domain datasets plus robustness slices; the maker's own) — so the numbers do not rank them. Test both on your own labelled examples.

Which is cheaper, bev or jevany?
