  # NOTE: This repository is now superseded by https://huggingface.co/bertin-project/bertin-roberta-base-spanish. This model corresponds to the `beta` version of the model using stepwise over sampling trained for 200k steps with 128 sequence lengths. Version 1 is now available and should be used instead.
  
  # BERTIN
  
  BERTIN is a series of BERT-based models for Spanish. This one is a RoBERTa-large model trained from scratch on the Spanish portion of mC4 using [Flax](https://github.com/google/flax), including training scripts.
  
  This is part of the
  [Flax/Jax Community Week](https://discuss.huggingface.co/t/open-to-the-community-community-week-using-jax-flax-for-nlp-cv/7104), organised by [HuggingFace](https://huggingface.co/) and TPU usage sponsored by Google.
  
  ## Spanish mC4
  
  The Spanish portion of mC4 containes about 416 million records and 235 billion words.
