Dimitris Papadopoulos: biodecision and Omar (kouhxp): gutsy, compared on what they decide, where they run, what they cost and what their publishers report.
| Property | lighteternal/biodecision | kouhxp/gutsy |
|---|---|---|
| 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. | Omar (kouhxp)'s CPU decision model: a Qwen3.5-0.8B fine-tune shipped as GGUF for llama.cpp that answers yes/no, choice and score questions with a probability per option plus a 'none of these' reject probability, served by a local Jev-style HTTP runtime. |

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 gutsy from Omar (kouhxp). Both have open weights you can download and run. Both answer choice, score, noul and classify questions. Only gutsy answers route. gutsy is the smaller model, at 800M parameters to 4.0B. biodecision is licensed other; gutsy, apache-2.0.
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), gutsy 73.2% on JevBench public set (231 items; 169 correct), the maker's own run with Q8_0 — so the numbers do not rank them. Test both on your own labelled examples.
biodecision: Free (open weights). gutsy: Free (open weights). Open weights cost nothing per call beyond your own hardware.
Yes, both: systemone pull lighteternal/biodecision and systemone pull kouhxp/gutsy download the weights.
