> perplexity.ai/ specifically uses web sources to construct natural language.

I am going to guess that even though it uses the GPT language model, it works fundamentally differently than ChatGPT.

My guess is, Perplexity AI is a traditional search engine, that first finds a list of links that match your questions. And then it feeds text from those links to the GPT language model to write a summary of the results.

Whereas ChatGPT produces text based only on the trained deep neural net.

Maybe I am guessing wrong how Perplexity AI works. Maybe it works in a different manner.
