Overview

This project is designed to demonstrate the use of Retrieval-Augmented Generation (RAG) and LangChain technology to build a context-aware newspaper article generator. The tool retrieves relevant information from Wikipedia based on a user query, generates a brief article in three paragraphs, and creates a catchy headline for the article.

Features

• Retrieval-Augmented Generation (RAG): Retrieves contextually relevant information from Wikipedia to enhance the quality and relevance of generated articles.
• LangChain Integration: Utilizes LangChain's Runnable components to create a modular and composable sequence of operations for article generation.
• Text Generation and Summarization: Employs GPT-2 for text generation and a summarization model for headline creation.
