You can even do this with LLM as a judge as well. Feed screenshots into a LLM as a judge panel and get them to rank the design 1-10. Give the LLM judge panel a few different perspectives/models to get a good distribution of ranks, and establish a rank floor for test passing.

Parent mentioned "subjective look and feel", LLMs are absolutely trash at that and have no subjective taste, you'll get the blandest designs out of LLMs, which makes sense considering how they were created and trained.

LLMs can get you to about a 7.5-8/10 just by iterating itself. The main thing you have to do is just wireframe the layout and give it the agent a design that you think is good to target.

Again, they have literally zero artistic vision and no, you cannot get an LLM to create a 7.5 out of 10 web design or anything else artistic, unless you too miss the facilities to properly judge what actually works and looks good.

[CuriouslyC]

You can get an AI to produce a 10/10 design trivially by taking an existing 10/10 design and introducing variation along axes that are orthogonal to user experience.

You are right that most people wouldn't know what 10/10 design looks/behaves like. That's the real bottleneck: people can't prompt for what they don't understand.

Yeah, obviously if you're talking about copying/cloning, but that's not what I thought the context here was, I thought we were talking about LLMs themselves being able to create something that would look and feel good for a human, without just "Copy this design from here".
