i gave Opus 5 the same prompt (one-shot)
for some reason it decided to restrict itself by creating a self-contained HTML file.
even with that, the results are convincing. the landing page layout seems cleaner and the 3D is working just fine
i'd say it's on par with Kimi K3 on this exercice, but it would probably have been better if Opus hadn't restricted itself
Kimi K3 vs GPT-5.6 Sol (one-shot)
GPT-5.6 gets mogged pretty hard, Kimi K3 outperforms by far.
Again, Kimi's taste is better and its 3D capabilities are way cleaner.
One thing that I notice is that Kimi seems to be less "lazy". It keeps on iterating and improving its design and does not content itself with the bare minimum.
