A training-free layer that turns an open LLM into a decision model. It reads typed choice, yes/no and score answers from one prefill, removes option-order bias with no labels and, from a few hundred labels, calibrates or fits a closed-form head. Weights stay untouched.
A family of open System One models by Mark Marosi, decider-0.8b, decider-2b, decider-4b and decider-35b-a3b on Qwen3.5 bases, that softmax letter logits at an answer slot. This page carries decider-2b v11.

Questions
What is the difference between anyjev and decider?
anyjev is from Nokia and decider from Mapika. Both have open weights you can download and run. Both answer choice, score, noul, classify and route questions. decider is the smaller model, at 1.9B parameters to 8.0B.
Which is more accurate, anyjev or decider?
They report on different suites — anyjev 77.1% on LocalLLaMA/typed-decisions (2,000 held-out decisions), L2 with 300 labels per question, decider 75.2% on Decider regression set, 28 held-out tasks (decider-2b v11) — so the numbers do not rank them. Test both on your own labelled examples.
Which is cheaper, anyjev or decider?
anyjev: Free (open weights). decider: Free (open weights). Open weights cost nothing per call beyond your own hardware.
Can I run anyjev or decider locally?
Yes, both: systemone pull nokia/anyjev and systemone pull mapika/decider download the weights.
