Brief

Peter Gostev reports a strong qualitative improvement from using Codex's new Interactive Playwright skill with GPT-5.4 xHigh for UI-related prompting. He attributes the gain to the model actively looking at and navigating the interface via computer use, saying prior attempts with similar workflows had not worked for him, but this version performed well enough that he plans to use it for future UI work.

This is actually cool - I tried the same prompt for the new Interactive Playwright skill in Codex & GPT-5.4 xHigh - the one above is with the skill and the one below is without. What the skill does is uses the computer use capability of GPT-5.4 to look and navigate the UI. This never worked for me before, but with GPT-5.4 this is the first time I can actually see a massive difference. You can see how the first scene is much more coherent, higher fidelity and complete. The one below is missing a lot of elements and isn't as rich in detail. I'll keep using it for any UI work now.
