Roblox Launches Cube, an Open-Source AI Model Family That Generates 3D Game Assets From Text

Roblox launches Cube, an open-source AI model family that generates 3D game assets, objects, and scenes directly from text prompts, with model weights publicly available on Hugging Face and trained on 2.8 million synthetic 3D assets.

• Roblox releases Cube, an open-source family of 3D foundation models aimed at generating 3D objects, scenes, and assets directly from text prompts, with model weights publicly available on Hugging Face.
• The latest updates include Cube 3D v0.5, which introduces higher-fidelity 3D generation, bounding box conditioning, and improved text adherence, trained on approximately 2.8 million synthetic 3D assets, as well as CubePart, an open-vocabulary part-controllable 3D generator that produces game-engine-ready segmented meshes.
• The project is open-source on GitHub, supports CUDA, Apple Silicon, and standard Python environments, and invites the broader research community to contribute toward the long-term vision of full 3D intelligence for game development.
