Dimitris Papadopoulos: biodecision and Convai Innovations: laya-multilingual-noulxp, compared on what they decide, where they run, what they cost and what their publishers report.

| Summary | 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 multilingual (Apache-2.0), fp32-o23: checked against the model's own answers, none changed. Not made by Convai Innovations. |

Figures are from each model’s manifest; accuracy and latency are what the publishers report, on their own suites and hardware. Add a third model.
biodecision is from Dimitris Papadopoulos and laya-multilingual-noulxp from Convai Innovations. Both have open weights you can download and run. Both answer choice, score, noul and classify questions. Only laya-multilingual-noulxp answers route. laya-multilingual-noulxp is the smaller model, at 322M parameters to 4.0B. biodecision is licensed other; laya-multilingual-noulxp, apache-2.0.
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-multilingual-noulxp does not, so there is no comparison to make without your own test.
biodecision: Free (open weights). laya-multilingual-noulxp: Free (open weights). Open weights cost nothing per call beyond your own hardware.
By their publishers’ figures, biodecision answers in about 39 ms at the median and laya-multilingual-noulxp in about 44.9 ms — measured on different hardware, so treat it as a rough guide.
Yes, both: systemone pull lighteternal/biodecision and systemone pull convai-innovations/laya-multilingual-noulxp download the weights.
