“Antidoom” training aims to reduce small AI models’ “doom loops”

A user says small models with thinking capabilities can get stuck in “doom loops” on complex tasks, and that Liquid AI uses final token preference optimization (FTPO) as “antidoom” training. They share a tutorial described as explaining these loops, how to reduce them with FTPO, and how to implement a custom DPOTrainer class in TRL for the technique.
