What is Decision Model?

A model that answers a fixed question with a typed result, such as a choice, a probability or a score, in one forward pass instead of generating text. Liquid AI's d1-3B takes 30 ms per decision on an M5 Pro (vendor-reported). Ollama serves decision models through /v1/systemone and, since v0.40.4, ollama run --ask; LM Studio 0.4.26 added /v1/decisions.
