Repeated post-training is not Self-improving: Diagnosing Scientific Amnesia in Continual DPO Pipelines

Jianzhe Lin, Fei Wang, Xiaolin Li +2

Industrial LLM teams often ship behavior updates by repeatedly DPO-training a base model on sequences of related preference-data campaigns. The dominant failure mode in this regime…
