Decision Modelsdecisionmodels.io
One API, many open decision models.
Decision models don’t write text. They read a situation and a set of options and return one answer per option with a probability, in a single forward pass. That makes them fast and cheap enough to sit in the middle of any workflow. Decision Models hosts strong open ones behind one API that speaks the same request format as Jev, TypeSafe AI’s decision model.2 (note)
