It's definitely gotten better at image->html workflows. Here's a test comparing Astra (currently SOTA at this) vs Grok 4.7:

Designs: https://image.non.io/78795662-8bfc-4e14-8d72-3738392aa6b3.we...

Astra's build: https://html.non.io/annui/

Grok's build: https://html.non.io/Annui-grok/

Additional prompt instructions: "Add scrolling clouds behind the statues. Dynamically light the statues based on mouse position. Use diffui to generate the normal maps/depth maps/roughness maps of the objects, and to separate out the assets on to different layers."

Overall I find these models are getting good at following image as a source of instructions, but their refinement of the output varies heavily between the models. Astra's final output feels more polished, has better visual contrast, and the animations between the pages are smoother. Grok also chose to light all of the background elements, which imo overcooks it a bit.

Still though, for the price it's a great starting point.
