Ask an LLM to invent a new word and post it here, I will be waiting. You will see that it simply combines words already in the training data.

I'm not sure what the point of this exercise is. My prompt to ChatGPT: "Create a new English word with a reasonably sounding definition. That word must not come up in a Google search." Two attempts did come up in a search, the third was "Thaleniq (noun)". Definition: The brief feeling that a conversation has permanently changed your opinion of someone, even if nothing dramatic was said. Nothing in Google. There, a new word, not sure it proves or disproves anything. Or is it time to move the goal posts?

Why is everyone who responds to this with a real example immediately flagged/dead?

HN autokills LLM generated comments. People don’t seem to believe this, but there’s proof for you.

Splifket

Definition: That highly specific, short-lived burst of nervous energy that makes you accidentally drop a small object (like a pen, a guitar pick, or a piece of LEGO) immediately after picking it up.

Does a random sequence of letters qualify as a new word?

"Who cares if they just predict the next token?"

Exactly. I also only write one word at a time. Who knows what is going on in order to come up with that word.
