# DistilBERT base model (cased)

This model is a distilled version of the [BERT base model](https://huggingface.co/bert-base-cased).
It was introduced in [this paper](https://arxiv.org/abs/1910.01108).
The code for the distillation process can be found
[here](https://github.com/huggingface/transformers/tree/master/examples/distillation).
This model is cased: it does make a difference between english and English.

All the training details on the pre-training, the uses, limitations and potential biases are the same as for [DistilBERT-base-uncased](https://huggingface.co/distilbert-base-uncased).
We highly encourage to check it if you want to know more.

## Evaluation results

When fine-tuned on downstream tasks, this model achieves the following results:
