Tencent Hunyuan

Tencent Hunyuan publishes HY-World 2.0 for generated and reconstructed 3D worlds, with HY-Embodied-0.5 covering a separate embodied-reasoning lane.

What this company is for

Tencent makes the open 3D asset track easier to follow.

Consumer access. Local open source

Visitor can see. Public repos, model cards, reports for 3D worlds, embodied AI.

Where the claim stops. For developers and technical readers, not a creator app.

What to open first

HY-World 2.0 is the generated-3D stack. HY-Embodied is the robot-facing stack.

HY-World 2.0 reconstructs, generates, and simulates persistent 3D worlds from text, images, and video. Public GitHub, Hugging Face, and arXiv materials make it inspectable in a way Marble is not.

HY-Embodied-0.5 is a different Tencent lane: embodied foundation models for spatial reasoning, planning, and robot-facing perception. Do not collapse both into one world-generator claim.

Who it is for

This company page is for people who need code, weights, and reports.

Tencent's public world-model value on this site is reproducibility. Meshes, Gaussian splats, reconstruction, and engine-adjacent materials are the HY-World questions. Embodied benchmarks are the HY-Embodied questions.

If the reader wants a browser product with account onboarding, Marble remains the clearer creator surface. If they want robot-control world models with open checkpoints, also compare Robbyant.

How to verify

Read the repo and model card before repeating engine-ready claims.

HY-World 2.0's May 2026 generation-code expansion is a dated source, not a blanket statement that every Unity or Unreal scene is production-ready. Check the current repository and Hugging Face card for what actually shipped.

HY-Embodied-0.5-X is likewise a checkpoint and paper signal. Keep robot-planning claims inside the cited benchmark scope.

Release history

April–May 2026: HY-World 2.0 code releases

Following the April 16 HY-World 2.0 release, the repository added HY-Pano 2.0 on May 11 and world-generation code on May 18. The update also pointed readers to WorldStereo 2.0 code and weights, the Hugging Face model card, and the technical paper.

These releases expanded the inspectable research stack and its reproducibility. They did not make the stack a turnkey hosted creator product; use the repository instructions to check the requirements and available components.
