The real announcement here is the impending release of their " 4D generation " tech, a feature for the Cube Foundation Model that allows "creators and players to generate fully functional objects" that can be ported into Roblox , the platform its billions of users actually play on and spend money in."
"Are we supposed to pretend that isnt expedition 33 or are we selling that ai generation is theft on purpose? - Mjl8 (@xMJL8x) February 5, 2026 The genAI world model addendum was featured made by the official Roblox X account to its 4D generation announcement, which explained that the "real-time, action conditioned world model" has been "trained on a combination of data, including proprietary Roblox 3D avatar/world interaction data.""
Roblox revealed a real-time, action-conditioned world model, a generative AI tool intended to produce interactable videos and auto-generate immersive worlds. The world model was shown alongside a larger 4D generation feature for the Cube Foundation Model that enables creators and players to generate fully functional objects that can be ported into Roblox and used within the platform's economy. The company stated the model was trained on a combination of data, including proprietary Roblox 3D avatar and world interaction data. The demonstration included imagery resembling Clair Obscur: Expedition 33, prompting public accusations of plagiarism and debate about training data provenance.
