zero123 XL

Congratulations for the released of zero123 XL!!! Is it trained using exact the same model as zero123, and just differs in data?

It seems something is weird here since both the zero123-xl.ckpt and the 10500.ckpt are the exact same file size.

they did not change the model structure, just finetuned on more data with objaverse-xl as suggested in objaverse-xl's preprint

FYI: https://objaverse.allenai.org/objaverse-xl-paper.pdf

@tydia correct, zero123-xl is designed as a drop-in replacement for zero123. Previously zero123 showed some signs of overfitting when trained on objaverse for an extended period of time, so with zero123-xl we decided not to scale the model while scaling the dataset.

May I ask where the zero123-xl.ckpt is? In the hugging face model, I can only find 105000.ckpt and 165000.ckpt.
