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.
A ModernBERT-large encoder with an option-marker head. Premise and options are packed into one sequence and each option's marker is scored in a single bidirectional pass; version 1.2 makes the scoring order-invariant.

Fastino fast-decisions suite (17 datasets)
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.
Questions
What is the difference between gliner2-5-decide and von?
gliner2-5-decide is from Fastino Labs and von from wfzyx. gliner2-5-decide has open weights and a hosted API; von has open weights you can download and run. 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 395M.
Which is more accurate, gliner2-5-decide or von?
They report on different suites — gliner2-5-decide 60.2% on Fastino fast-decisions suite (17 datasets), von 63.9% on JevBench public standard tier — so the numbers do not rank them. Test both on your own labelled examples.
Which is cheaper, gliner2-5-decide or von?
gliner2-5-decide: Hosted, price not published, or free to self-host. von: Free (open weights). Open weights cost nothing per call beyond your own hardware.
Which is faster, gliner2-5-decide or von?
By their publishers’ figures, von answers in about 18 ms at the median and gliner2-5-decide in about 38.3 ms — measured on different hardware, so treat it as a rough guide.
Can I run gliner2-5-decide or von locally?
Yes, both: systemone pull fastino-labs/gliner2-5-decide and systemone pull wfzyx/von download the weights.
