ChatGPT 5.4 is out, so I put it head-to-head against Claude Code on real design tasks. In this video, I test both tools on actual codebases to redesign my SaaS landing page, then throw in a one-shot flight simulator app challenge to see how well they handle vague prompts, UI decisions, and real-world coding tasks. No benchmark fluff. Just real outputs, real apps, and a straight comparison of which one actually feels more useful when you're building. I also share my honest thoughts on bad prompts, why that matters for so-called autonomous AI tools, and which model I’d actually trust more for design-heavy workflows right now. If you're building apps, SaaS, or AI tools with Claude Code, check out Build With Luke. I’m rebuilding it right now with lessons on shipping your first AI tool, better web design prompts, Claude skills, and real SaaS build breakdowns.
