Roblox launches Build: mobile-first AI creation that turns text prompts into games

Roblox announced Build on July 16, a mobile-first creation tab within the Roblox app that lets anyone turn text prompts into basic games. Powered by a broad set of AI models including both open-source and proprietary Roblox models, Build handles gameplay mechanics, environment, characters, visual style, and sound without leaving Roblox.

A creator can type a prompt like 'Let's make a cozy adventure game set in a dense forest with environmental obstacles.' Build will automatically generate a starting point for the creator to iterate on, playtest, and share with friends or publish to Roblox.

Shared backend with Studio

Build extends Roblox Studio into the mobile app with a shared backend, models, and chat history. Creators can start work in Build and enhance their creation with the broader capabilities of Studio, or launch agents from Studio and check in on progress from their mobile device.

Because Roblox's proprietary AI models are trained on a uniquely large set of 3D models and gaming-specific data, they can generate functional 3D objects and full 3D scenes that integrate easily into working games using existing creation tools.

Availability

Select Build features, including the ability to publish games, will be available in public alpha beginning July 28 in New Zealand, with deployment to more regions over the coming months. A base-level version of Build will be available at no cost, with additional paid options for power users.

Procedural Models generate parametric 3D assets from a text prompt or image, with settable parameters for reshaping and refining. Cube, Roblox's 3D foundation model, turns a prompt into game-ready objects from simple props to vehicles and weapons. A scene-generation model for entire editable 3D scenes from a single prompt is coming soon.
