Detailed breakdown for poetry
Poetry is where Sonnet 4.5 earns its name.
It brings a craftsperson's attention to meter, imagery, and the weight of individual words — the kind of sensitivity that separates verse from poetry.
GPT-5.2 approaches poetry differently: it takes creative risks, reaches for unexpected images, and sometimes produces lines that genuinely surprise you.
But poetry rewards precision more than surprise.
A daring image that doesn't land disrupts a poem in a way it wouldn't disrupt prose.
Sonnet 4.5 understands that restraint is a creative choice, that what you leave out of a poem shapes it as much as what you put in.
For poets working within formal constraints — sonnets, villanelles, ghazals — Sonnet is the clear choice.
For experimental work where you want to be pushed into unfamiliar territory, GPT-5.2 can be a valuable provocation.
But for most poetry work, Sonnet 4.5 is the model that treats your craft with the seriousness it deserves.
