BabyLM Dataset

This download includes LM Pretraining data for the 2023 CoNLL/CMCL shared task, The BabyLM Challenge. The (unzipped) data is not large, only ~700MB.

Note that there is also a multi-lingual version of this dataset, that is availabled under the multi-lingual branch of the dataset repository.

Contents of this download

  • 10M: 10M-word training set for the strict-small track.
  • dev: Development set for both tracks (10M words)
  • test: Test set for both tracks (10M words)

Each directory above contains a single .txt file from each of the 10 domains listed below.
