+# BigBirdPegasus model (large)
+
+BigBird, is a sparse-attention based transformer which extends Transformer based models, such as BERT to much longer sequences. Moreover, BigBird comes along with a theoretical understanding of the capabilities of a complete transformer that the sparse model can handle. 
+
+BigBird was introduced in this [paper](https://arxiv.org/abs/2007.14062) and first released in this [repository](https://github.com/google-research/bigbird).
+
+Disclaimer: The team releasing BigBird did not write a model card for this model so this model card has been written by the Hugging Face team.
+
+## Model description
+
+BigBird relies on **block sparse attention** instead of normal attention (i.e. BERT's attention) and can handle sequences up to a length of 4096 at a much lower compute cost compared to BERT. It has achieved SOTA on various tasks involving very long sequences such as long documents summarization, question-answering with long contexts.
+
+## How to use
+
+Here is how to use this model to get the features of a given text in PyTorch:
+
+```python
+from transformers import BigBirdPegasusForConditionalGeneration, BigBirdPegasusTokenizer
+
+# by default encoder-attention is `block_sparse` with num_random_blocks=3, block_size=64
+model = BigBirdPegasusForConditionalGeneration.from_pretrained("google/bigbird-pegasus-large-pubmed")
+
+# decoder attention type can't be changed & will be "original_full"
+# you can change `attention_type` (encoder only) to full attention like this:
+model = BigBirdPegasusForConditionalGeneration.from_pretrained("google/bigbird-pegasus-large-pubmed", attention_type="original_full")
+
+# you can change `block_size` & `num_random_blocks` like this:
+model = BigBirdPegasusForConditionalGeneration.from_pretrained("google/bigbird-pegasus-large-pubmed", block_size=16, num_random_blocks=2)
+
+text = "Replace me by any text you'd like."
+inputs = tokenizer(text, return_tensors='pt')
+prediction = model.generate(input_ids=input_ids, num_beams=5, length_penalty=0.8)
+prediction = tokenizer.batch_decode(prediction)
+```
+
+## Training Procedure
+
+This checkpoint is obtained after fine-tuning `BigBirdPegasusForConditionalGeneration` for **summarization** on **pubmed dataset** from [scientific_papers](https://huggingface.co/datasets/scientific_papers).
