Kimi K3 vs Claude Fable 5 on a 3D coding task
OwariDa · x · 2026-07-21
A user compares Kimi K3 with Claude Fable 5 on the same 3D football stadium task.
- Kimi took nearly 3 hours versus under an hour for Fable 5.
- But the extra time went into end-to-end testing across desktop/tablet/mobile, taking screenshots, finding failures, fixing them, and adapting for low-end hardware and low FPS.
- The output was a cleaner React + Three.js codebase with proper components, while Fable produced a single stuffed HTML file.
- The takeaway is that Kimi felt more like a full “vibe coding” workflow, even if it was slower.
