# zephyr-7b-beta-ExPO

The extrapolated (ExPO) model based on `HuggingFaceH4/zephyr-7b-beta` and `HuggingFaceH4/mistral-7b-sft-beta`, 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.
