There's a substantive difference in whether the artist is using the tool, or the tool works on its own. A paintbrush doesn't produce a painting by itself, a human needs to apply an incredibly specialized creative skillset, in conjunction with the paintbrush to do so.
An LLM takes a prompt and produces a painting. No sane person would say that I 'drew' the painting in question, even if I provided the prompt.
> Regarding copyright, we copyright output not input. Otherwise most photography would be uncopyrightable.
We copyright things that require creative input. A list of facts or definitions did not require creative input, and is therefore not copyrightable.
Using an LLM does not meet the bar for creative input.
