# LLaMA3-iterative-DPO-final-ExPO

The extrapolated (ExPO) model based on [`RLHFlow/LLaMA3-iterative-DPO-final`](https://huggingface.co/RLHFlow/LLaMA3-iterative-DPO-final) and [`RLHFlow/LLaMA3-SFT`](https://huggingface.co/RLHFlow/LLaMA3-SFT), as in the "[Weak-to-Strong Extrapolation Expedites Alignment](https://arxiv.org/abs/2404.16792)" paper.

Specifically, we obtain this model by extrapolating from the weights of the SFT and DPO/RLHF checkpoints, achieving superior alignment with human preference.
