A family of open System One models by Mark Marosi that softmax option-letter logits at an answer slot: decider-0.8b, 2b, 4b and 35b-a3b on Qwen3.5 bases, decider-12b on Gemma-4-12B-it, and training-free readouts of larger chat models. This page carries decider-2b v11.
A 364M Hebrew decision encoder on NeoDictaBERT: give it a state, a question and 2 to 7 free-text options and it returns a probability for each option in one forward pass, about 70 ms on a laptop CPU. Hebrew only.

Questions
What is the difference between decider and nativ-he-decision?
decider is from Mapika and nativ-he-decision from Yoav Pinto. Both have open weights you can download and run. Both answer choice, classify and route questions. Only decider answers score and noul. decider reads up to 32K tokens of state, against 1K tokens for nativ-he-decision. nativ-he-decision is the smaller model, at 364M parameters to 1.9B. decider is licensed apache-2.0; nativ-he-decision, cc-by-4.0.
Which is more accurate, decider or nativ-he-decision?
They report on different suites — decider 75.2% on Decider regression set, 28 held-out tasks (decider-2b v11), nativ-he-decision 96.2% on nativ-bench user-intent task, 4 options (MASSIVE Hebrew, 2,973 items; the maker's own suite) — so the numbers do not rank them. Test both on your own labelled examples.
Which is cheaper, decider or nativ-he-decision?
decider: Free (open weights). nativ-he-decision: Free (open weights). Open weights cost nothing per call beyond your own hardware.
Can I run decider or nativ-he-decision locally?
Yes, both: systemone pull mapika/decider and systemone pull yoav-pinto/nativ-he-decision download the weights.
