FineWeb-LMs: BERT
This repository presents a BERT model that was pretrained on the 10BT subsets of FineWeb and FineWeb-Edu.
Pretraining Details
The released BERT model is part of my TensorFlow Model Garden LMs project.
The pretraining was done on a v3-32 TPU VM Pod, provided by the amazing TRC program. Detailed cheatsheets are available:
tl;dr: The model was pretrained for 1M steps with a global batch size of 512, a sequence length of 512 using a vocab size of 64k.
Checkpoint Evaluation with ScandEval
We evaluate the last 5 checkpoints (1M, 951k, 901k, 851k and 851k) with a recent version of ScandEval to check their performance and also compare it with popular encoder-only models such as BERT, RoBERTa or ELECTRA:
