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.
Qwen3.5-4B with a merged rank-16 LoRA distilled from 17,408 teacher questions and 30,000 public training rows, read out as a temperature-scaled softmax over answer-letter logits. Also in 9B, 2B and GGUF.

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 jevk5?
gliner2-5-decide is from Fastino Labs and jevk5 from Alibi Serikbay. gliner2-5-decide has open weights and a hosted API; jevk5 has open weights you can download and run. Both answer choice, score, noul, classify and route questions. Only gliner2-5-decide answers extract. gliner2-5-decide is the smaller model, at 340M parameters to 4.0B.
Which is more accurate, gliner2-5-decide or jevk5?
They report on different suites — gliner2-5-decide 60.2% on Fastino fast-decisions suite (17 datasets), jevk5 78.4% on JevBench public hard tier — so the numbers do not rank them. Test both on your own labelled examples.
Which is cheaper, gliner2-5-decide or jevk5?
gliner2-5-decide: Hosted, price not published, or free to self-host. jevk5: Free (open weights). Open weights cost nothing per call beyond your own hardware.
Which is faster, gliner2-5-decide or jevk5?
By their publishers’ figures, jevk5 answers in about 13.2 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 jevk5 locally?
Yes, both: systemone pull fastino-labs/gliner2-5-decide and systemone pull alibi-serikbay/jevk5 download the weights.
