Are there any technical details about this website and how it works?

I asked it to quote Marcus Aurelius, then for 5 more similar quotes - it didn't get the context that I meant from the same person and found 5x others. But otherwise it was very snappy and I've seen similar results from ChatGPT.

For "Write an openfaas function with the python3-http templates to convert from text to speech" (something I saw a community member share) - it did a much worse job (just showing how to access Amazon Polly) - it also didn't have any styling or code blocks.

I'd be interested to know more about the model that's being used here.
