Roblox Cube

Roblox built Cube as a generative foundation model for 3D intelligence, and the open release centers on text-to-shape generation for game assets: a shape tokenizer turns meshes into discrete tokens, and the model generates new shapes from text prompts, with bounding box conditioning added in the July 2025 v0.5 release and part-controllable generation arriving with CubePart in May 2026. Texture generation and scene layout generation sit on the published roadmap. Running inference takes a minimum of 16 GB of VRAM with 24 GB recommended, tested on NVIDIA L40S, H100, and A100 cards as well as Apple Silicon M2 through M4 machines, and installation is a git clone followed by pip install -e with an optional meshlab extra. The catch is licensing: code and weights ship under the CUBE3D Research-Only RAIL-MS license, which limits use to academic or research purposes and forbids commercial products, hosted services, and commercial derivatives. Even so, it remains a rare case of a major game platform publishing its 3D foundation model in the open, and the repository holds about 1.2k GitHub stars.
