Starling-LM-7B-alpha-ExPO
The extrapolated (ExPO) model based on berkeley-nest/Starling-LM-7B-alpha and openchat/openchat_3.5, as in the "Weak-to-Strong Extrapolation Expedites Alignment" paper.
Specifically, we obtain this model by extrapolating (alpha = 0.5) from the weights of the SFT and DPO/RLHF checkpoints, achieving superior alignment with human preference.
