ModernBERT-base-fineweb-edu-example

One-off run using a modified version of the original Fineweb-Edu quality filter regression training code, simply replacing the original model (snowflake-embed-m, a model fine-tuned on BERT-base) with ModernBERT-base.

w/o extensive tuning, the model trains considerably faster than BERT-base, and gets +5 Weighted F1:

(for some reason, the currently available annotated dataset is identical, except that it's missing 124 of the 125 5-rated examples. These are so anecdotal they have no real impact on the weighted metrics.)
