# Donut (base-sized model, fine-tuned on DocVQA) 

Donut model fine-tuned on DocVQA. It was introduced in the paper [OCR-free Document Understanding Transformer](https://arxiv.org/abs/2111.15664) by Geewok et al. and first released in [this repository](https://github.com/clovaai/donut).

Disclaimer: The team releasing Donut did not write a model card for this model so this model card has been written by the Hugging Face team.

## Model description

Donut consists of a vision encoder (Swin Transformer) and a text decoder (BART). Given an image, the encoder first encodes the image into a tensor of embeddings (of shape batch_size, seq_len, hidden_size), after which the decoder autoregressively generates text, conditioned on the encoding of the encoder.

## Intended uses & limitations

This model is fine-tuned on DocVQA, a document visual question answering dataset.

We refer to the [documentation](https://huggingface.co./docs/transformers/main/en/model_doc/donut) which includes code examples.
