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.
Unofficial NoulXP package of Convai Innovations' Laya (English) (Apache-2.0), fp32-o23: checked against the model's own answers, none changed. Not made by Convai Innovations.

Questions
What is the difference between biodecision and laya-noulxp-cpu?
biodecision is from Dimitris Papadopoulos and laya-noulxp-cpu from Convai Innovations. Both have open weights you can download and run. Both answer choice, score, noul and classify questions. Only laya-noulxp-cpu answers route. laya-noulxp-cpu is the smaller model, at 421M parameters to 4.0B. biodecision is licensed other; laya-noulxp-cpu, apache-2.0.
Which is more accurate, biodecision or laya-noulxp-cpu?
Only biodecision publishes an accuracy figure (75.3% on BioDecision v2 held-out test set (63,432 overlap-screened decisions from public biomedical benchmarks; the maker's own split)); laya-noulxp-cpu does not, so there is no comparison to make without your own test.
Which is cheaper, biodecision or laya-noulxp-cpu?
biodecision: Free (open weights). laya-noulxp-cpu: Free (open weights). Open weights cost nothing per call beyond your own hardware.
Which is faster, biodecision or laya-noulxp-cpu?
By their publishers’ figures, biodecision answers in about 39 ms at the median and laya-noulxp-cpu in about 116 ms — measured on different hardware, so treat it as a rough guide.
Can I run biodecision or laya-noulxp-cpu locally?
Yes, both: systemone pull lighteternal/biodecision and systemone pull convai-innovations/laya-noulxp-cpu download the weights.
