GPT-5.5 Pro pulls this off technically with the same prompt, but with a somewhat boring nature poem that doesn't hold together quite as well, and without the same self-referential nature of Fable.

@emollick "without vowels, all that's left of poetry is shivering, growling, and falling asleep." (and emdashes)

@footrecovering That’s an odd response. You okay?

@emollick The “(y)” line is incredible. Truly jaw dropping. Anyone who thinks AI can’t be as (or more) creative than humans - with just as much emotional resonance - is deluding themselves. What percentage of average humans can do something like this?

@emollick Why does it consider "y" as the vowel instead of u?

@emollick In the (a e y) stanza, I’m genuinely surprised that it did something pretty complex: not forcing the rhyme at the end of a thought, but allowing meter to dominate (terse / Rehearse)

@excesstential I mean, I agree it’s fundamentally a gimmick, not expressing anything particularly deep or important.

But I think it’s good (gimmicky) poetry, and I’d be proud if I’d written it.

@emollick Fable is also very good at automatic writing.

@bellaforristal Scouring the dictionary for words that fit certain requirements and using them in a sentence is a perfect task for an LLM. I would not consider this "good poetry" but taste is subjective

@bellaforristal it’s a parlor trick and devoid of capital P poetry

@emollick brb, off to tattoo "Shy myths spry nymphs spy Styx's wry sky"

@emollick ITT: people who have never voluntarily read a poem in their life, marveling at how great this poetry is

@bellaforristal You're subhuman. Useless, worthless, rotted-out brain

@TJangodarkblade Eh, I agree it’s trite. This isn’t, like, professional poet level - but I don’t know any professional poets. But it’s better than almost any amateur poet I know.

@emollick This rules

@bellaforristal Writing a poem about the poem you're currently writing is so trite

@bellaforristal Perfectly suitable response to that embarrassment of a post

@emollick this kind of layered constraint, rhyme scheme plus progressive vowel exclusion plus meter, used to fall apart by stanza 3 on older models. tracking what you *cant* use while still writing coherent verse is genuinely hard token prediction.

@bellaforristal idk if I'm jaded but it didn't really do it for me, except for "All ballads sag; all sagas crack" which for some reason hits me just right

@bellaforristal literally it makes a mistake in the third one by not mentioning Y
