# T5-Large Fine-tuned on the combined XSum + CNN/DailyMail Datasets

**Task:** Abstractive Summarization (English)  
**Base Model:** google-t5/t5-large  
**License:** MIT

## Overview

This model is a T5-Large checkpoint fine-tuned jointly on [XSum](https://huggingface.co/datasets/EdinburghNLP/xsum) and [CNN/DailyMail](https://huggingface.co/datasets/abisee/cnn_dailymail) datasets. It produces concise, abstractive summaries and has been widely adopted as a baseline in summarization research.

## Performance ~ On XSum test set

| Metric | Score |
|--------|-------|
| ROUGE-1 | 36.77 |
| ROUGE-2 | 14.69 |
| ROUGE-L | 30.06 |
| Loss | 1.64 |
| Avg. Length | 18.6 tokens |



## Usage

### Quick Start

```python
from transformers import pipeline

summarizer = pipeline("summarization", model="sysresearch101/t5-large-finetuned-xsum-cnn")

article = "Your article text here..."
summary = summarizer(article, max_length=80, min_length=20, do_sample=False)
print(summary[0]['summary_text'])
```

### Advanced Usage

```python
from transformers import AutoTokenizer, AutoModelForSeq2SeqLM

tokenizer = AutoTokenizer.from_pretrained("sysresearch101/t5-large-finetuned-xsum-cnn")
model = AutoModelForSeq2SeqLM.from_pretrained("sysresearch101/t5-large-finetuned-xsum-cnn")

inputs = tokenizer("summarize: " + article, return_tensors="pt", max_length=512, truncation=True)
outputs = model.generate(
    **inputs,
    max_length=80,
    min_length=20,
    num_beams=4,
    no_repeat_ngram_size=2,
    length_penalty=1.0,
    repetition_penalty=2.5,
    use_cache=True,
    early_stopping=True,
    do_sample = True,
    temperature = 0.8,
    top_k = 50,
    top_p = 0.95
)

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

## Training Data

- [XSum](https://huggingface.co/datasets/EdinburghNLP/xsum): BBC articles with single-sentence summaries
- [CNN/DailyMail](https://huggingface.co/datasets/abisee/cnn_dailymail): News articles with multi-sentence summaries
- 
## Intended Use
- **Primary:** Summarization.
- **Secondary:** Educational demonstrations, reproducible baselines, Research benchmarking, academic studies on summarization


## Limitations
- Optimized for English news text; performance may vary on other domains
- Tends to produce very concise summaries (18-20 tokens average)
- No built-in fact-checking or content filtering
