Roblox has introduced a new set of generative AI tools with the launch of 4D generation, now available in beta. With this update, the platform takes a major step forward in AI-driven content creation. Instead of focusing only on static 3D assets, Roblox now enables interactive and functional objects inside games and experiences.
The new tools run on Roblox’s in-house Cube Foundation Model, which powers the company’s broader AI strategy.
Evolution of the Cube Foundation Model
Roblox first revealed its foundation model in March 2025 with the launch of Cube 3D. At that time, Cube 3D allowed developers to generate static 3D objects from text prompts. Over time, Roblox expanded its use across Roblox Studio tools and in-experience APIs.
Now, the company is moving to the next stage. Roblox aims to give AI-generated objects built-in behavior so they function naturally during gameplay. As a result, objects no longer remain simple visual assets.
From Static Assets to Interactive Gameplay Objects
With 4D generation in beta, creators can let players use simple natural-language commands to build fully working in-game objects. For example, a generated car can include spinning wheels and ready-to-use scripts. Therefore, players can drive it instantly without manual scripting or advanced modeling.
According to Roblox engineers, the system combines object meshes with predefined rule sets called schemas. These schemas define how parts connect and how behaviors like movement and interaction work. Consequently, objects behave in predictable and realistic ways.
More Creative Freedom for Developers and Players
Roblox says this technology significantly expands creative freedom. Through 4D generation, users can build vehicles, tools, and even complex machinery in real time. Additionally, creators can reduce time spent on repetitive asset creation.
As a result, developers can focus more on gameplay design, mechanics, and storytelling. Meanwhile, players gain more control over how experiences evolve inside games.
Early members of the Roblox developer community have already started testing the feature. They are experimenting with new gameplay ideas made possible by AI-generated, dynamic entities.
Part of Roblox’s Long-Term AI Strategy
This launch fits into Roblox’s broader plan to deeply integrate AI across its creation ecosystem. The company believes AI can democratize content creation and speed up development workflows.
Roblox reportedly supports over 85 million daily active users, including hobbyists, independent developers, and professional studios. Therefore, tools like Cube and 4D generation could lower entry barriers for new creators who lack advanced art or programming skills.
What Comes Next
Roblox emphasizes that the current beta represents only an early step. In the future, the company plans to expand Cube and related AI systems even further.
Eventually, Roblox wants creators to generate entire scenes—and later full game environments—using only natural-language descriptions. If successful, this shift could redefine how virtual worlds are built on the platform.
