- Roblox launched a beta AI tool that creates interactive in-game models based on natural-language prompts
- The company claims these tools aim to make its user-built platform more accessible for creators
- Roblox also hinted at early “world model” research that could eventually enable real-time scene changes
On Wednesday, Roblox unveiled an AI-powered feature called “4D creation” that transforms natural-language prompts into fully functional in-game models. This innovation takes its creator tools beyond static 3D objects. Reuters
The timing is crucial as Roblox aims to broaden the range of creators on its platform—not only experienced developers but also artists and, down the line, players within games. The company reported finishing the third quarter with over 150 million average daily active users.
This comes amid a heated scramble among tech giants to harness generative AI for building interactive worlds, beyond just creating images or text. Alphabet’s Google rolled out its own prompt-based “world” model last week, while Roblox execs have been vocal about pursuing similar projects.
Roblox’s new 4D creation tool, currently in beta, expands on its previous AI model that could produce a single 3D object but lacked the ability to generate interactive behavior. According to Roblox, “4D” refers to adding interactivity—think doors that open, wheels that spin, and physics that respond as players anticipate.
“You’re trying to bring all of them together,” Anupam Singh, Roblox’s senior vice president of engineering for foundation AI and infrastructure, told Reuters. He described the tool as one designed to assist both coders and visual artists. “Our highest goal would be that a player can create inside a game.”
Roblox revealed that its Cube foundation model powers the technology, letting creators enable it within experiences where players type a prompt to generate functional items—like a drivable car. The system relies on “schemas,” which are rulesets breaking objects into parts, then adds behaviors to make them interactive. Roblox
One early experiment is a project called “Wish Master,” created by a developer named Laksh. He’s been using the tools to let players actually “wish” objects into existence. “I thought it would be amazing to create something similar for players to use in-game,” Laksh said, reflecting on earlier trials with Roblox Studio’s AI assistant.
Laksh revealed that early access players created over 160,000 objects with the 4D feature. “Those using 4D generation have boosted their play time in Wish Master by an average of 64%,” he noted.
Roblox revealed the beta kicks off with just two schemas: a five-part car and a single-mesh object. The plan is to grow into an “open vocabulary” system that spans thousands of real-world items. They also mentioned a “retargeting” step that adjusts scripts to fit the dimensions of the generated model, ensuring the behavior stays intact even as shapes shift.
Roblox is also pushing what it calls “real-time dreaming,” a research project centered on AI “world models” — systems designed to grasp an environment’s rules to predict and generate future events. In a virtual briefing, Singh showcased a prerecorded demo featuring a Viking-themed scene that shifted dynamically after prompts introduced a tsunami and then a boat. Product director Karun Channa emphasized the work remains in a “research stage” with no set timeline. Theverge
Roblox’s move into generative AI isn’t without risks: these tools often yield unpredictable outputs, and the company’s safety measures have already caught the attention of U.S. state and international regulators. On top of that, developers and artists are increasingly resisting AI tools, while tech companies grapple with copyright lawsuits tied to how their models are trained.
Roblox is ramping up server capacity to handle its growing user base and investing heavily in AI models and safety, Reuters revealed. The company is banking on AI creation tools—starting with 4D objects now and eventually moving to full “world” generation—to fuel its community of developers in crafting the next big hit.
