This is the smallest version of 24 smaller BERT models (English only, uncased, trained with WordPiece masking) released by google-research/bert.

These BERT models was released as TensorFlow checkpoints, however, this is the converted version to PyTorch. More information can be found in google-research/bert or lyeoni/convert-tf-to-pytorch.
