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.
Laya fine-tune that scans untrusted text (extracted files, knowledge-base documents, agent skills, tool descriptions) for prompt injection and data exfiltration in English and German, as a noul question answered in one forward pass. 322M parameters, PyTorch and ONNX.

Questions
What is the difference between biodecision and laya-cybersec?
biodecision is from Dimitris Papadopoulos and laya-cybersec from TextCortex. Both have open weights you can download and run. Both answer noul and classify questions. Only biodecision answers choice and score. laya-cybersec is the smaller model, at 322M parameters to 4.0B.
Which is more accurate, biodecision or laya-cybersec?
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-cybersec does not, so there is no comparison to make without your own test.
Which is cheaper, biodecision or laya-cybersec?
biodecision: Free (open weights). laya-cybersec: Free (open weights). Open weights cost nothing per call beyond your own hardware.
Which is faster, biodecision or laya-cybersec?
By their publishers’ figures, biodecision answers in about 39 ms at the median and laya-cybersec in about 95.4 ms — measured on different hardware, so treat it as a rough guide.
Can I run biodecision or laya-cybersec locally?
Yes, both: systemone pull lighteternal/biodecision and systemone pull textcortex/laya-cybersec download the weights.
