Using Langchain and GPT-4 to Create a PDF Chatbot
Users discussed how to create a PDF chatbot using the GPT-4 language model and Langchain. They shared a step-by-step guide on setting up the ChatGPT API and using Langchain's Documentreader `PyPDFLoader` to convert PDF files into a format that can be fed to ChatGPT. The users also provided a link to a GitHub repository that demonstrates this process: https://github.com/mayooear/gpt4-pdf-chatbot-langchain.
One user mentioned using GPT-4 for writing a novel and pointed out the model's limitations in referencing data from conversations that are too far back. Another user suggested using the `gpt_index` to create an index and provide context when querying ChatGPT. The user also mentioned that there are paid services for this purpose, but it can be done more affordably by coding and using the API. A few resources were shared, including a YouTube tutorial: https://youtu.be/TLf90ipMzfE and two chatbot services: filechat.io and ChatPDF.Tags: Langchain, GPT-4, ChatGPT, PDF Chatbot, PyPDFLoader, gpt_index, filechat.io, ChatPDF
