I put three cutting-edge AI models to the test in a head-to-head design competition. Using the exact same prompt, I challenged Google’s Gemini 3, Anthropic’s Opus 4.5, and OpenAI’s Codex 5.1 to redesign my blog page, evaluating them on visual design quality, user experience improvements, and SEO optimization capabilities. One model produced a beautiful, polished, production-ready redesign. One was fine. And one completely whiffed. If you’re trying to figure out where each model fits in your workflow—design, planning, back-end, or something else—this episode will save you a lot of trial and error.

What you’ll learn:

1. How each AI model approaches the same design challenge differently

2. Why planning capabilities dramatically impact design quality

3. The specific visual and functional improvements each model made

4. Which model excels at front-end design versus back-end functionality

5. How to strategically choose the right AI model for different parts of your workflow

6. The importance of model-switching based on specific use cases
