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.
Uprelic's hosted decision API, run on GPUs in Paris. Answers noul, choice and score questions about text, JSON and up to 8 images, with a probability for every option and no generated text, on the same request shape as Jev. No weights; base model and size not disclosed.

Questions
What is the difference between biodecision and strom?
biodecision is from Dimitris Papadopoulos and strom from Uprelic. biodecision has open weights you can download and run; strom is only available as a hosted API. Both answer choice, score, noul and classify questions. Only strom answers route. biodecision is licensed other; strom, proprietary.
Which is more accurate, biodecision or strom?
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), strom 87.0% on JevBench public set (231 items), the maker's production run of Strom 1.0.7 on 1 Oct 2026 (Open-Jev harness format) — so the numbers do not rank them. Test both on your own labelled examples.
Which is cheaper, biodecision or strom?
biodecision: Free (open weights). strom: $0.042 / $0 per 1M. Open weights cost nothing per call beyond your own hardware.
Which is faster, biodecision or strom?
By their publishers’ figures, biodecision answers in about 39 ms at the median and strom in about 136 ms — measured on different hardware, so treat it as a rough guide.
Can I run biodecision or strom locally?
biodecision yes — systemone pull lighteternal/biodecision downloads its weights. The other is only served as a hosted API.
