tulu-2-dpo-13b-ExPO

The extrapolated (ExPO) model based on allenai/tulu-2-dpo-13b and allenai/tulu-2-13b, 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.
