Custom ChatGPT - Work in Progress

Welcome, candidates! This project is a custom-built chatbot application that mimics the functionalities of ChatGPT for personal use. It's built using Python and Django for the backend, and React with Next.js for the frontend. The application offers regular chatting capabilities with history stored in the database, streaming responses, and auto-generated titles using GPT-3.5. It also allows for title editing, conversation deletion, and message regeneration. The project currently supports model selection between GPT-3.5 and GPT-4 and features a custom Django admin page for managing conversations, versions, and messages.

Note: This project is a work in progress, with plans to add more features and functionalities. It serves as a platform to experiment with Next.js and create a personal version of ChatGPT with custom functionalities and features.
