> I'm not too mad about it not following my instructions

I'm a bit concerned about this - starting with GPT5, AI labs started doing this 'complete app from a prompt' sizzle demos. When I started working with GPT5 - which was supposed to be a qualitative jump, just like Fable is now, I tried to do a frontend, and discovered that it gave me a CSS-animated purple-blue interface with embossed buttons, gradient backgrounds and dropshadows.

It looked very cool, but it was a bit overwhelming (also broken), and I was really looking for a pedestrian Bootstrap job.

It required not inconsiderable amount of wrangling for GPT5 to stop doing this. So I don't really like the idea that these models have tons of implicit and hidden behavior, to 'soup up' pedestrian prompts.
