DPO vs SimPO: Removing Reference Model Alters Preference Tuning

A recent article explores the differences between Direct Preference Optimization (DPO) and Simplified Preference Optimization (SimPO) in the context of fine-tuning large language models. It highlights how SimPO's removal of the reference model during the optimization process leads to distinct tradeoffs compared to DPO. The piece delves into the underlying optimization mechanics and their implications for achieving desired model behaviors. AI
