Show HN: AI World Bakeoff – 9 models × 3 Three.js worlds

TL;DR

With the releases of Fable 5, gpt 5.6 sol, and Kimi K3 I was curious how these models would perform building vivid 3d worlds, especially a Chinese open-weight one like Kimi. I also threw in some budget models so you can see how drastic the quality differences are. ycombinator. com/item?

Nauti's Take

If you use AI for web or 3D prototyping, verify first whether a model produces clean Three. js code, consistent scene logic, and usable defaults.

A polished demo is weak evidence on its own when the source is a single creator showcase and there is still no clear signal on reproducibility across prompts, assets, and failure cases.
