We’re open-sourcing HY-World 2.0, a multimodal world model that generates, reconstructs, and simulates interactive *3D worlds* from text, images, and videos. Outputs can be integrated into game engines and embodied simulation pipelines. Key highlights: 🔹 One-click world generation Turn text or image into interactive 3D worlds automatically. 🔹 Pipeline-ready... show more

Wow this is truly something. Running this on an RTX 5070 using PyTorch 2.7.1 + CUDA 12.8, BF16, and FlashAttention-2 instead of the repo’s recommended PyTorch 2.4.0 + CUDA 12.4 stack. Doable.

wow its only 5GB

Amazing! Finally a proper announcement! We will cover this on tomorrow's @thursdai_pod show!

It's running on my computer😊 Used codex to install it for me🤪

👏👏👏

tencent owns stakes in epic, riot, and supercell. if world models actually worked for real game dev they'd be using this internally, not open sourcing it.

Perfection

i almost thought ‘ok they beat google’ until i realized it’s not open source

Tremendous release. So much of progress depends of strong world models

@llmgram

This is so incredible. I've been waiting for this for a long time.

Open source your most recent hy3d models with topology fixes instead.

Please can we get this on @replicate? ❤️

HY World 2 is coming!

Tecnent native playing field fr

Just in time for tax season

everyone's chasing the next big model but i'm just waiting for one tool that renders 3d worlds without forcing a new pipeline every week. until then this is just another marketing slide promising physics-aware movement while your gpu burns out exporting meshes

The first open-source world model that directly exports editable meshes and 3DGS into Unity and Unreal Engine!👍👍👍

Genau das Richtige für meine Simulationen zuhause. Die sphärische Darstellung erinnert mich an meine letzte Nachthimmels-Aufnahme. 🤩

Wow can't wait to test that

not open source...

@Scobleizer Super cool!

Is this in response to Lyra 2.0 by Nvidia?

Ouuuuuu much upgrade on1.5 will make something cool later or tomorrow with Ty.

@AethericaX ready to build your 7 worlds? 😎

@grok can I run it on my MacBook Pro m3 Max?

This is a massive leap for 3D content creation! The integration of 3DGS and mesh exports directly into Unity and Unreal Engine is a game-changer for development pipelines. I can't wait to try it out and see how it handles complex scene reconstructions! 🚀

Will end up with massive interesting game worlds!

Sweet, thank you Hunyuan!

HY-World 2.0 generating 3D worlds from text/images for game engines is revolutionary! Open-sourcing this multimodal model accelerates the democratization of world-building AI.

@grok Can I fine tune this model?

Bravo!🥳🥳🥳

This is the smart way to do it. Will be much more useful than video in the short term.

On my waitlist now!!!
