Visual comparison
Open 3D world stack, or polished persistent-world product workflow?
How close is open-source world generation to engine-ready 3D assets?
How does a polished product surface package world modeling?
HY-World 2.0: research-first open stack; Marble: product workflow.

Detailed table
The table is still available for source-backed comparison, but it no longer owns the first screen.
| Dimension | HY-World 2.0 | Marble |
|---|---|---|
| Organization | Tencent Hunyuan | World Labs |
| Primary framing | Multimodal 3D world model for reconstruction, generation, and simulation | Product workflow for high-fidelity persistent 3D worlds |
| Main output | Meshes, Gaussian splats, point clouds, reconstructed/generated 3D worlds | Persistent explorable 3D worlds with editing and export workflows |
| Access signal | GitHub, Hugging Face, arXiv; May 2026 generation code/weights expansion | Public product surface, World Labs account access, and Marble documentation |
| Best reader question | How close is open-source world generation to engine-ready 3D assets? | How does a polished product surface package world modeling? |
| Editorial role | Open reproducibility track for generated-3D worlds | Product and platform track for generated-3D worlds |
| Alternative role | Marble alternative when open code, model cards, and weights matter | Best HY-World alternative when product onboarding and creator workflow matter |
Yes, but only for the open technical workflow. HY-World 2.0 is a better Marble alternative when the reader wants public code, weights, and reconstruction or generation materials rather than a polished web product.
No. HY-World 2.0 and Marble both sit in generated 3D-world coverage, but they come from different organizations and expose different surfaces: Tencent's research-first open stack versus World Labs' product workflow.
HY-World 2.0 is stronger for inspecting open technical materials, while Marble is clearer as a creator-facing workflow with export-oriented product documentation.
FAQ
The FAQ explains how comparison pages keep reported, official, product, and research signals separate.
Systems that model environments, actions, spatial structure, or persistent state. Chatbots and plain video generators qualify only through a clear world-modeling bridge.
Video models appear only when they bridge generated clips to controllable spaces, physics-aware prediction, or agent-ready simulation — never overstated as finished world simulators.
Primary sources weigh most: official pages, research posts, papers, docs, code repositories, announcements. Secondary media stays labeled as reported unless independently confirmed.
Useful comments add source links, corrections, release-status notes, comparison questions, or concrete reader context. Comments are public immediately, so readers should avoid private information and unsupported promotional claims.
