For web app generation, gpt-5 seems to route my prompt to the reasoning model. Interestingly, gpt-4.1 often produced more creative or aesthetically interesting designs. In some cases, a bit of controlled hallucination (via temperature) is actually desirable, especially when generating UI ideas. Anyone else seeing this tradeoff?
I use image generation for UI layout and have Claude implement it with an actual UI library: usually MUI with theming, but honestly anything with a sane grid system is better than loose tailwind.
