I didn't know what SSE was, so I asked ChatGPT:

> What does 'SSE' stand for in the following code sample: <pasted fetch-sse.js>

"In this code sample, 'SSE' likely stands for "Server-Sent Events". It is the name of the fetchSSE function and it is used to fetch data from a server using the Server-Sent Events protocol. This protocol allows a server to push data to a client in real-time, rather than requiring the client to continually poll the server for updates."

Not sure how accurate this is but it gave me enough information to look into it more!

The only thing here is instead of copy-pasting it into ChatGPT, you get to use a browser extension that does the job. Pretty convenient actually.

So technically, we are still using https://chat.openai.com/chat, with the UI

ChatGPT is in fact just a chat prompt on top of Davinci3, plus a markdown renderer
