A ChatGPT UI. Stream OpenAI responses with Langchain and Nextjs

A complete UI for an OpenAI powered Chatbot inspired by https://www.ai.com.

It makes use of Nextjs streaming responses from the edge. Langchain is used to manage the chat history and calls to OpenAI's chat completion. It uses a basic BufferMemory as Memory.

This is part 3 of a Langchain+Nextjs series:

Disclaimer: The code in this series is not meant for production or be taken as an example for best practices. It is meant to be be a starting point and conceptual example of how to implement those kind of technologies. There are bugs and no tests! You have been warned! ;)

Getting Started!

First, run the development server:

npm run dev
# or
yarn dev
# or
pnpm dev

Open http://localhost:3000 with your browser to see the result.

You can start editing the page by modifying app/page.tsx. The page auto-updates as you edit the file.

This project uses next/font to automatically optimize and load Inter, a custom Google Font.
