Liquid AI Open-Sources Antidoom: A Final Token Preference Optimization (FTPO) Method that Reduces Doom Loops in Reasoning Models
Liquid AI open-sourced Antidoom, a method that targets repeated "doom loop" behavior in reasoning models. The approach uses Final Token Preference Optimization to retrain the token that triggers the loop, reducing loop rates in tests on LFM2.5-2.6B and Qwen3.5-4B.
