filipe(@filicroval):Kimi K3 vs DeepSeek v4 Flash (0731) to design a landing page for a $10,000 luxury phone. Same prompt, same harness. it's actually impressive to see DS4 close to K3's results considering it's weight. it's also faster and cheaper to run. K3 won, of course, but the difference is not huge.

DeepSeek v4 Flash (0731) vs Kimi K3 (10x more weights) i gave both the exact same prompt, in the exact same harness: one-shot a luxury product landing page ($10,000 "ARC-01" concept object). results in the video. my take: Kimi K3: wins on polish. Better typography hierarchy, more confident use of negative space, and the hero product shot integration is genuinely beautiful DeepSeek v4 Flash: very close. The structure is right, the copy is right, the layout logic is right. It loses on finish, not on fundamentals. a 10x smaller model getting ~90% of the way there. a year ago this gap would have been embarrassing. mind you it cost less than $0.10 for 6 build iterations and 8 QA passes. small models aren't "good for their size" anymore. they're just good.
