CamemBERT(a)-v2: A Smarter French Language Model Aged to Perfection

CamemBERTv2 is a French language model pretrained on a large corpus of 275B tokens of French text. It is the second version of the CamemBERT model, which is based on the RoBERTa architecture. CamemBERTv2 is trained using the Masked Language Modeling (MLM) objective with 40% mask rate for 3 epochs on 32 H100 GPUs. The dataset used for training is a combination of French OSCAR dumps from the CulturaX Project , French scientific documents from HALvest , and the French Wikipedia.

The model is a drop-in replacement for the original CamemBERT model. Note that the new tokenizer is different from the original CamemBERT tokenizer, so you will need to use Fast Tokenizers to use the model. It will work with CamemBERTTokenizerFast from transformers library even if the original CamemBERTTokenizer was sentencepiece-based.
