Two paths into the same future. Pick the one that matches what you want to see, build, or understand.
Visual comparison
Do you need an open 3D world stack to inspect, or a polished product workflow for creating persistent worlds?
How close is open-source world generation to engine-ready 3D assets?
How does a polished product surface package world modeling for creators and developers?
Both belong in generated 3D-world coverage, but HY-World 2.0 is a research-first open stack while Marble is a 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, and reconstructed or generated 3D worlds | Persistent explorable 3D worlds with editing and export workflows |
| Access signal | GitHub repo, Hugging Face model card, arXiv paper, and May 2026 expansion of generation code and weights | 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 for creators and developers? |
| Editorial role | Open reproducibility track for generated-3D worlds | Product and platform track for generated-3D worlds |
| Alternative role | Best 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.
The site tracks systems that model environments, actions, spatial structure, or persistent simulated state. Pure text chatbots and ordinary video generators are only included when they provide a clear bridge toward interactive or physical world modeling.
Video models are included only when they help explain the path from generated clips to controllable spaces, physics-aware prediction, or agent-ready simulation. The site keeps that distinction explicit so video generation is not overstated as a finished world simulator.
Primary sources carry the most weight: official product pages, research posts, papers, documentation, code repositories, and company announcements. Secondary media can be referenced, but it stays labeled as reported or adjacent unless independently confirmed.
