Usage

from transformers import AutoModelForSeq2SeqLM, AutoTokenizer
import re

# Load model
model = AutoModelForSeq2SeqLM.from_pretrained("ciorant/news-summarizer")
tokenizer = AutoTokenizer.from_pretrained("ciorant/news-summarizer")

def summarize_news(article_text, max_length=128):
    inputs = tokenizer(article_text, return_tensors="pt", truncation=True, max_length=512)
    
    outputs = model.generate(
        inputs.input_ids,
        max_length=max_length,
        num_beams=4,
        early_stopping=True,
        do_sample=False,
        length_penalty=1.0
    )
    
    summary = tokenizer.decode(outputs[0], skip_special_tokens=True)
    
    # Clean up spacing around punctuation
    summary = re.sub(r'\s+([.,!?;:])', r'\1', summary)
