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.
Fastino's open-weight decision model. A DeBERTa-v3-large encoder that scores label sets supplied at runtime, answers single-label, multi-label, yes/no and ordinal questions in one pass, and extracts spans and relations.

Questions
What is the difference between biodecision and gliner2-5-decide?
biodecision is from Dimitris Papadopoulos and gliner2-5-decide from Fastino Labs. biodecision has open weights you can download and run; gliner2-5-decide has open weights and a hosted API. Both answer choice, score, noul and classify questions. Only gliner2-5-decide answers extract and route. gliner2-5-decide is the smaller model, at 340M parameters to 4.0B. biodecision is licensed other; gliner2-5-decide, apache-2.0.
Which is more accurate, biodecision or gliner2-5-decide?
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), gliner2-5-decide 60.2% on Fastino fast-decisions suite (17 datasets) — so the numbers do not rank them. Test both on your own labelled examples.
Which is cheaper, biodecision or gliner2-5-decide?
biodecision: Free (open weights). gliner2-5-decide: Hosted, price not published, or free to self-host. Open weights cost nothing per call beyond your own hardware.
Which is faster, biodecision or gliner2-5-decide?
By their publishers’ figures, gliner2-5-decide answers in about 38.3 ms at the median and biodecision in about 39 ms — measured on different hardware, so treat it as a rough guide.
Can I run biodecision or gliner2-5-decide locally?
Yes, both: systemone pull lighteternal/biodecision and systemone pull fastino-labs/gliner2-5-decide download the weights.
