 ### Problem Description : 
 1. When you pass a large text to Open AI, it suffers from a 4K token limit. It cannot take an entire pdf file as an input
 2. Open AI sometimes becomes overtly chatty and returns irrelevant response not directly related to your query. This is because Open AI uses poor embeddings.
