SOMEONE RAN KIMI K3 AND CLAUDE FABLE 5 THROUGH THREE REAL FRONTEND BUILDS. AN E-COMMERCE SITE, A 3D FIGHTING GAME, A FLIGHT SIMULATOR.
Fable 5 came out more polished every time, sophisticated animations on the product page, added sound design on the fighting game.
Kimi K3 came out radically cheaper every time, 8.7x cheaper on the e-commerce build, roughly a tenth of the cost on the fighting game, and noticeably faster to finish.
Both handled the 3D flight simulator, rain, lightning, real environmental rendering, without issue.
The actual verdict is not which model is better. It is which one your specific budget and polish requirements point to.
