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