A 0.4B decision model made from the first 20 layers of Qwen3-0.6B plus a small attention head that compares options. It answers choice, noul and score questions in one pass, and choice order cannot change its answer by construction. Non-commercial licence.
An independent Jev-shaped reproduction on DeBERTa-v3-large. One state and any number of choice, score and yes/no questions go in, and a calibrated distribution per question comes out of one forward pass. Public gold labels only.

Questions
What is the difference between bev-decider and open-jev-deberta-v3-large?

Only open-jev-deberta-v3-large answers classify. bev-decider reads up to 2K tokens of state, against 512 tokens for open-jev-deberta-v3-large. open-jev-deberta-v3-large is the smaller model, at 434M parameters to 478M. bev-decider is licensed cc-by-nc-4.0; open-jev-deberta-v3-large, apache-2.0.
Which is more accurate, bev-decider or open-jev-deberta-v3-large?
They report on different suites — bev-decider 74.7% on avbiswas/bev-decision test split (5,000 held-out questions over 2,617 states), the maker's own, open-jev-deberta-v3-large 85.4% on Kotoba held-out test, seen question types (banking77, SST-5, BoolQ) — so the numbers do not rank them. Test both on your own labelled examples.
Which is cheaper, bev-decider or open-jev-deberta-v3-large?
