When models are aligned with comparisons, human or reward-model labelers may prefer longer answers even when the extra text is not better. In standard DPO, the implicit reward sums per-token log-probability differences, so it can grow with response length. SimPO uses average per-token log probability, removes the need for a separate reference model, and adds a target reward margin between preferred and rejected responses. The SimPO paper reports chat-based evaluations on AlpacaEval 2, MT-Bench, and Arena-Hard; these results are tied to its tested models and training setups. Length-normalized objectives can reduce verbosity bias, but aggressive normalization can also encourage under-informative answers. Evaluation should assess completeness and correctness alongside length-controlled preference results.
