-- [Model Cards with first commit information](https://huggingface.co/datasets/librarian-bots/card_with_first_commit): a dataset containing model cards for models hosted on the Hugging Face hub with first commit information for each model. Model cards are intended to help communicate the strengths and weaknesses of machine learning models. Whilst these model cards are primarily intended to be read by a human they are themselves also interesting corpus that can be used to explore models hosted on the Hub in various ways.
