📺 T5 YouTube Summarizer

This is a fine-tuned flan-t5-base model for abstractive summarization of YouTube video transcripts. The model is trained on a custom dataset of video transcriptions and their manually written summaries.

✨ Model Details

Base Model: flan-t5-base
Task: Abstractive Summarization
Training Data: YouTube video transcripts and human-written summaries
Max Input Length: 512 tokens
Max Output Length: 256 tokens
Fine-tuning Epochs: 5
Tokenizer: T5Tokenizer (pretrained)

🧠 Intended Use

This model is designed to generate short, informative summaries from long transcripts of educational or conceptual YouTube videos. It can be used for:

Quick understanding of long videos
Automated content summaries for blogs, platforms, or note-taking tools
Enhancing accessibility for long-form spoken content

🚀 How to Use

python

from transformers import T5ForConditionalGeneration, T5Tokenizer

# Load the model
model = T5ForConditionalGeneration.from_pretrained("bilal521/flan-t5-youtube-summarizer")
tokenizer = T5Tokenizer.from_pretrained("bilal521/flan-t5-youtube-summarizer")

# Define input text
text = "The video talks about coordinate covalent bonds, giving examples from..."

# Preprocess and summarize
inputs = tokenizer.encode("summarize: " + text, return_tensors="pt", max_length=512, truncation=True)

summary_ids = model.generate(
    inputs,
    max_length=256,
    min_length=80,
    num_beams=5,
    length_penalty=2.0,
    no_repeat_ngram_size=3,
    early_stopping=True
)

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