vsHunyuanWorld is Tencent's open-source scene generation framework; Sculpty generates explorable worlds in a browser. Both produce 3D you can keep, so this comes down to who runs the hardware.
HunyuanWorld gives you the model: auditable, modifiable, no vendor, no per-generation cost once the machines are yours. For a team with GPUs and engineering time — or with data that cannot leave the building — that is the stronger position, and open weights mean nothing can be taken away or repriced. Sculpty is the better answer for everyone else: worlds generate from a browser on credits with nothing to install, in a studio that also covers five object engines, texturing, remesh, photoreal renders and print ordering. The real comparison is not features, it is whether running inference is a thing you want to do.

Every engine answers the same prompt box. When one misreads what you asked for, switching costs a dropdown instead of another subscription.

The code and weights are. The GPUs, the engineering and the maintenance are not, and for most people that is the larger number.
No — Sculpty is a hosted studio. If self-hosting is a requirement, an open-weight model is the right route.
