Paper claims 0.77% training, but released checkpoint actually uses 6.31% of parameters

Peer review and reproducibility problems are not new

The poster argues that these trust and reproducibility issues have existed for a long time and likely could have been observed 15 years ago as well. They say peer review is broken, but also note that these problems did not stop the scientific system from being a huge net positive overall.

In a reply, they add a concrete example from their analysis: one paper claimed its method trained only 0.77% of the base model’s parameters, presenting that as a headline advantage. But the checkpoint actually released trained 6.31% of parameters — about 8× more. The 0.77% figure only held under a narrower condition, which they say is just one example of the broader issue.
