A training-free layer that turns an open LLM into a decision model. It reads typed choice, yes/no and score answers from one prefill, removes option-order bias with no labels and, from a few hundred labels, calibrates or fits a closed-form head. Weights stay untouched.
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.

Questions
What is the difference between anyjev and biodecision?
anyjev is from Nokia and biodecision from Dimitris Papadopoulos. Both have open weights you can download and run. Both answer choice, score, noul and classify questions. Only anyjev answers route. biodecision is the smaller model, at 4.0B parameters to 8.0B. anyjev is licensed apache-2.0; biodecision, other.
Which is more accurate, anyjev or biodecision?
They report on different suites — anyjev 77.1% on LocalLLaMA/typed-decisions (2,000 held-out decisions), L2 with 300 labels per question, biodecision 75.3% on BioDecision v2 held-out test set (63,432 overlap-screened decisions from public biomedical benchmarks; the maker's own split) — so the numbers do not rank them. Test both on your own labelled examples.
Which is cheaper, anyjev or biodecision?
anyjev: Free (open weights). biodecision: Free (open weights). Open weights cost nothing per call beyond your own hardware.
Can I run anyjev or biodecision locally?
Yes, both: systemone pull nokia/anyjev and systemone pull lighteternal/biodecision download the weights.
