I’ll ask GPT-6.1 to design a landing page for AI travel planner (the same experiment I did with Sonnet 5.5).
This use case is great for two specific reasons:
It gives GPT-6.1 an opportunity to make meaningful choices around typography, imagery/illustration, hierarchy, editorial composition, UI cards, color, whitespace and motion.

the only thing I miss here is the buck you spent for each. it's not the consumption that matters, GPT 6 Luna will eat up 1M tokens, who cares, it's $1, while if Opus 5 did that it's like $50.
same difference Sonnet 4.6 is more expensive than Sonnet…
