The model, Cube 3D, creates 3D models from a text prompt.
Roblox is pushing the boundaries of AI innovation with the launch of Cube 3D, its groundbreaking foundational AI model designed to revolutionize 3D object creation. In an ambitious move, the company is not only deploying Cube 3D but also open-sourcing it, signaling a new era of AI-assisted creativity within its platform and beyond.
Revolutionizing 3D Content Creation
With Cube 3D, Roblox aims to redefine the way developers craft digital environments, making 3D asset generation faster, more efficient, and more intuitive. “With Cube, we intend to make 3D creation more efficient,” Roblox stated in its press release. “With 3D mesh generation, developers can quickly explore new creative directions and increase their productivity by deciding rapidly which to move forward with.”
Traditionally, designing 3D models has been a time-intensive process requiring technical expertise and intricate detailing. Cube 3D seeks to streamline this workflow, allowing creators to prototype, iterate, and bring their visions to life at an unprecedented pace.
How Cube 3D Works: AI-Powered Innovation
The core strength of Cube 3D lies in its advanced training methodology. Inspired by cutting-edge natural language processing (NLP) models, Cube 3D applies a similar token-based approach to understanding and generating 3D objects.


“Much like how state-of-the-art language models predict the next token in a sentence, Cube 3D is trained to recognize 3D shapes as tokens and predict the next shape token to form a complete object,” Roblox explains. This novel approach allows Cube 3D to intelligently generate detailed and cohesive 3D structures, opening up a world of creative possibilities for developers.
The model has been trained using a diverse dataset comprising licensed and publicly available 3D assets, along with experience data from the extensive Roblox ecosystem. According to Samantha Spielman, a Roblox spokesperson, this ensures Cube 3D has a rich understanding of various object types and styles, making it highly versatile for game and content creation.
The Future of Cube 3D: Multimodal Capabilities
Roblox’s vision for Cube 3D extends far beyond its current capabilities. The company is actively working on making Cube 3D a multimodal model, which means it will soon be able to generate 3D assets using various input types, including images, text, and video.
“It will ultimately be a multimodal model, trained on text, images, video, and other types of input – and will integrate with our existing AI creation tools,” Roblox states. This integration could dramatically enhance AI-powered content generation, making it easier than ever for developers to bring their ideas to life with minimal effort.
Implications for Game Developers and Beyond
The impact of Cube 3D extends beyond Roblox’s ecosystem. By open-sourcing the model, Roblox is inviting developers, researchers, and AI enthusiasts to experiment with and refine the technology. This move not only fosters innovation but also aligns with the growing trend of democratizing AI tools for broader applications in game development, virtual reality (VR), augmented reality (AR), and even industrial design.
For independent game creators, Cube 3D could mean shorter development cycles, reduced costs, and greater creative flexibility. For large-scale studios, it presents an opportunity to scale up production while maintaining artistic quality. The potential applications are vast, ranging from procedural world-building to real-time asset customization.
A New Era of AI-Driven Creativity
With Cube 3D, Roblox is not just enhancing its platform but shaping the future of AI-driven content creation. By leveraging machine learning to simplify and accelerate 3D modeling, the company is setting new standards for efficiency and innovation in digital design.
As AI continues to evolve, tools like Cube 3D will play a pivotal role in transforming creative industries, making high-quality 3D asset generation accessible to everyone—from seasoned developers to aspiring creators with no prior experience in 3D modeling.
The open-sourcing of Cube 3D marks the beginning of an exciting journey, and as Roblox continues to refine and expand its capabilities, the possibilities for AI-assisted creativity are virtually limitless. Stay tuned as Cube 3D reshapes the digital landscape, one 3D object at a time.
