Well, it is GPT-3; through dev told me on Discord it's finetuned, prompt is more limited than what's possible (I think), to just generate lots of text one has to spam enter (with an empty prompt)...

But if you just do "custom" scenario, it works well.

Here's navy seal copypasta parody, like Gwern did (through he had much longer prompt; I could fit only one long and one super-short example): https://pastebin.com/Lc7tC8j9

I've been most impressed by this so far, because I didn't expect GPT-3 to handle language other than English so well: https://www.reddit.com/r/slatestarcodex/comments/hqnteu/my_t...
