zephyr-7b-dpo-full-ExPO
The extrapolated (ExPO) model based on alignment-handbook/zephyr-7b-dpo-full and alignment-handbook/zephyr-7b-sft-full, as in the "Weak-to-Strong Extrapolation Expedites Alignment" paper.
Specifically, we obtain this model by extrapolating (alpha = 0.3) from the weights of the SFT and DPO/RLHF checkpoints, achieving superior alignment with human preference.
This model achieves the 18.0% win rate and 20.2% LC win rate on AlpacaEval 2.0.
