The most-downloaded open System One reproduction. Merged Qwen3.5 fine-tunes, trained on about 95 public decision sets, then calibration-aware RL and a rank-64 LoRA, that softmax letter logits at an answer slot.
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.

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 decider and gliner2-5-decide?
decider is from Mapika and gliner2-5-decide from Fastino Labs. decider has open weights you can download and run; gliner2-5-decide has open weights and a hosted API. 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 2.0B.
Which is more accurate, decider or gliner2-5-decide?
They report on different suites — decider 80.2% on Decider 67-task regression set, 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, decider or gliner2-5-decide?
decider: 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, decider or gliner2-5-decide?
By their publishers’ figures, decider answers in about 3.2 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 decider or gliner2-5-decide locally?
Yes, both: systemone pull mapika/decider and systemone pull fastino-labs/gliner2-5-decide download the weights.
