## Usage

```python
from transformers import BartTokenizer, BartForConditionalGeneration

# Load model and tokenizer
tokenizer = BartTokenizer.from_pretrained("alansary/full_finetuning-bart-summarization")
model = BartForConditionalGeneration.from_pretrained("alansary/full_finetuning-bart-summarization")

# Example usage
text = "Your long text to summarize here..."
inputs = tokenizer.encode("summarize: " + text, return_tensors="pt", max_length=512, truncation=True)

# Generate summary
with torch.no_grad():
    summary_ids = model.generate(
        inputs, 
        max_length=128, 
        num_beams=4, 
        early_stopping=True,
        no_repeat_ngram_size=2
    )

summary = tokenizer.decode(summary_ids[0], skip_special_tokens=True)
print(summary)
```

## Model Performance

Performance metrics will be updated after evaluation completion.

## Limitations and Bias

This model inherits the limitations and biases present in the base BART model and training datasets. Users should be aware of potential biases in summarization outputs.
