Roblox has introduced a powerful new generative AI world model, but its public demonstration has quickly become the center of controversy within the gaming community.
The new system, described by Roblox as a real time, action conditioned world model, is designed to generate interactive video worlds that players and creators can explore. However, users on social platform X noticed that one of Roblox’s demo prompts appeared to closely resemble environments and character designs from Clair Obscur Expedition 33, the 2025 Game of the Year winner developed by Sandfall Interactive.
Why the Demo Raised Concerns
The demo showcased a prompt involving a woman in a glowing cave, which users pointed out looked strikingly similar to specific locations and character outfits from Clair Obscur Expedition 33, including the Flying Waters area and the protagonist Maelle’s attire.
While Roblox did not confirm that the demo footage was directly sourced from the game, the resemblance was strong enough to trigger concerns about how training data and reference material are being used in generative AI systems.
Sandfall Interactive has not yet issued an official statement regarding the situation.
Roblox Explains How the AI Model Works
Roblox clarified that the new AI system is meant to be used inside Roblox Studio, allowing creators to generate immersive worlds using text, image, and video prompts. According to the company, the model was trained on a combination of data, including proprietary Roblox 3D avatar and world interaction data.
The announcement was shared as part of a broader reveal of Roblox’s 4D generation technology, powered by the Cube Foundation Model.
This technology allows creators to generate functional 3D objects, such as vehicles or tools, that can be imported directly into Roblox experiences.
Roblox also revealed that the AI world model is currently running internally at 16 frames per second at 832 by 480 resolution, with plans to improve performance over time.
Real Time Dreaming and the Future of Creation
In an official statement, Roblox described its long term vision as real time dreaming, where fully playable video worlds can be generated from simple prompts. The company also introduced the idea of a Dream Theater, where one user generates a world while others watch and guide the experience through prompts.
To support large scale worlds, Roblox says its engine uses cloud based streaming and level of detail systems to efficiently deliver high fidelity environments even on lower end devices.
The company also highlighted its massive dataset, noting that Roblox records around 13 billion hours of player interaction every month, which it uses to train intelligent NPCs capable of reasoning and interacting inside 3D worlds.
Industry Reactions and Open Questions
The controversy surrounding the demo mirrors wider concerns in the gaming industry about AI training data and intellectual property.
While Roblox insists its technology relies on proprietary data and creator driven prompts, the visual similarity to an award winning game has reignited debates around originality, fair use, and transparency in generative AI.
For now, Roblox continues to push forward with AI powered creation tools, positioning them as the next evolution of user generated content. Whether this technology becomes a breakthrough for creators or a legal challenge for the industry may depend on how clearly companies can define the boundaries of AI generated worlds in the months ahead.
