# 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](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. |
