LLMs seem fundamentally incapable of producing truly diverse outputs, truly creative and different responses to the same prompts in different runs. Because you and me use the same Claude, if you want a website and I want a website, we'll get (almost) the same website. This is not some BS about "the average of its training data", most of the LLM style (both in design and in text) comes from reinforcement learning. You could RL Claude to produce a very different style, but you couldn't RL it to produce a different style for me than it does for you.
I think this is also where a lot of the complaints about "Claude writing" come from.
It's worth mentioning that they do RL for aesthetics to some degree based on human expert feedback, but whatever the model tends to produce quickly becomes debased by its ubiquity. They could RL for output diversity, but it's less well studied and likely to cause minor regressions in coding performance, at least until the algorithms are dialed in.
Same. I honestly am very satisfied with the aesthetics of free Wordpress blogs. Like Terry Tao has. I also have one.
So it's what lies between saying "I want x website" -[.....] -> Code+Assets
The issue has to do with specification fidelity, in short a grill-me style aesthetic interrogation using illustrative tooling - ascii diagrams for specifying layout, copy and user-flow, image-gen mockups for higher fidelity mockups. References are also very important for nailing down the aesthetical qualities. I've noticed it's far better vs purely text description to simply gather up a mood-board telling the llm to find commonalities and come up with a design system and brand guide.
So I don't believe it's an unsolvable problem, it's simply a lack of effort on the implementors part. Also there's probably some survivor's bias here (you won't notice an intentionally designed vibe-coded site)
For example here's one reference exploration site i recently made with grok: https://explorer.withfudge.com/
