Claude Fable 5 vs Opus 4.8: Same Prompt, Shocking Result

Anthropic just released Claude Fable 5, a new Mythos-class model, and in this video I put it head-to-head against Claude Opus 4.8. To make the test fair, I gave both models the exact same prompt and asked them to build a landing page for my virtual instrument/VST in one single HTML file. No extra help. Same assets. Same instructions. Same challenge. Claude Opus 4.8 created a beautiful, polished landing page with particles, pricing sections, product cards, and a strong visual layout. But Claude Fable 5 surprised me with cleaner ideas, interactive audio buttons, better product breakdowns, and a design that felt slightly more useful for a real website. Both models did an amazing job, but I think Claude Fable 5 had the edge. Which one do you think built the better landing page?
