Here's a comparison of a image->html flow for GPT 6.1 Sol vs Opus 5.5.

Opus 5.5: https://html.non.io/lcars-opus-5.5

Overall, opus executes a bit better than 6.1 sol, which surprises me. Astra has been the best model for this flow so far, so the fact that Sol missed some alignment / vision pieces here is interesting. It's not bad by any means, but I think where Opus really wins is the motion animation of the svgs / final polish (scroll down to the "customize every detail" section on the homepage, the svg animation is beautiful for that).

Still, it executed quick and was quite cheap to run.
