Leonie of Liquid AI explains that small models with thinking capabilities get stuck in "doom loops" on complex tasks. Liquid AI's fix: "antidoom" training via Final Token Preference Optimization (FTPO).
They open-sourced a full tutorial notebook showing what doom loops are, how FTPO reduces them, and how to implement a custom DPOTrainer in TRL — available in the Liquid4All/cookbook repo (2.5k stars).
