A 4B biomedical decision model by Dimitris Papadopoulos: Qwen3.5-4B tuned with Together AI's Tev1 recipe on 1.75M pharma, clinical-trial and literature decisions. One forward pass gives a temperature-scaled probability per option. Research use only.
A 364M Hebrew decision encoder on NeoDictaBERT: give it a state, a question and 2 to 7 free-text options and it returns a probability for each option in one forward pass, about 70 ms on a laptop CPU. Hebrew only.

Questions
What is the difference between biodecision and nativ-he-decision?
biodecision is from Dimitris Papadopoulos and nativ-he-decision from Yoav Pinto. Both have open weights you can download and run. Both answer choice and classify questions. Only biodecision answers score and noul. Only nativ-he-decision answers route. nativ-he-decision is the smaller model, at 364M parameters to 4.0B. biodecision is licensed other; nativ-he-decision, cc-by-4.0.
Which is more accurate, biodecision or nativ-he-decision?
They report on different suites — biodecision 75.3% on BioDecision v2 held-out test set (63,432 overlap-screened decisions from public biomedical benchmarks; the maker's own split), nativ-he-decision 96.2% on nativ-bench user-intent task, 4 options (MASSIVE Hebrew, 2,973 items; the maker's own suite) — so the numbers do not rank them. Test both on your own labelled examples.
Which is cheaper, biodecision or nativ-he-decision?
biodecision: Free (open weights). nativ-he-decision: Free (open weights). Open weights cost nothing per call beyond your own hardware.
Can I run biodecision or nativ-he-decision locally?
Yes, both: systemone pull lighteternal/biodecision and systemone pull yoav-pinto/nativ-he-decision download the weights.
