@niplav It produced the phrase "AkGPT4-qãl äxkäfţt îţkul Tp'Iţkuil oixţü" when asked to translate from "The GPT-4 Large Language Model is able to write at least some Ithkuil", but it may or may not be total gibberish, as a second GPT-4 conversation was unable to make much sense of it (it could only spot that "AkGPT4" was likely talking about GPT-4 and that "Tp'Iţkuil" was likely a reference to the Ithkuil language itself)
@flats Thanks! I might take this to the subreddit to discover whether it has actually learned any Ithkuil
