Build extends Roblox Studio, which creators have been successfully using for years, into the Roblox app. With a shared back end, 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.

Powered by a broad set of AI models, including both open-source and proprietary Roblox models, Build handles gameplay mechanics, environment, characters, visual style, sound, and more—without leaving Roblox. Because these models are trained on a uniquely large set of 3D models and gaming-specific data, Roblox’s proprietary AI models are able to generate functional 3D objects and even full 3D scenes that can easily integrate into working games using our existing creation tools.

Build allows rapid exploration and refinement of ideas. This makes it a powerful tool for iterating on design, sharing with friends, and getting feedback. Upcoming releases will unlock flexibility for new and established creators to improve their games from our mobile app.

Select Build features, including the ability to publish games, will be available in public alpha to users in New Zealand beginning July 28. We will deploy Build out to creators and more regions over the coming months as we iterate on core functionality and expand its capabilities. During alpha testing, Build will be available to age-checked users 9 and older.* Published games that pass our robust safety checks will be globally available for age-checked users 16 and older. Before being added to the Roblox Select catalog, Build alpha-created games will undergo the extended review process all Roblox games follow. They will also join the same candidate pool and be ranked by the same retention-based discovery system as all other Roblox games. A base-level version of Build will be available at no cost to creators, with additional paid options for power users.

The Road Ahead for Build and Studio

We’re also shipping a new suite of tools for professional creators over the coming months. Available across Build and Studio, these tools will include:

• A playtesting agent that surfaces bugs before a single player experiences the game
• An analytics agent that lets creators ask anything about a game in plain language and get insights without needing to hunt through dashboards
• An experiment agent that identifies tests to run to drive higher engagement, retention, and monetization

Our recently launched Procedural Models generate parametric 3D assets from a text prompt or image. Creators can set parameters to reshape and refine, with no manual modeling or regeneration required. And Cube, Roblox’s 3D foundation model, turns a prompt into game-ready objects, from simple props to vehicles that drive and weapons that shoot. Coming soon, a new scene-generation model will build entire editable and playable 3D scenes from a single prompt. We’ll share more about these capabilities as they become available in the coming months.

Together, these updates bring Roblox closer than ever to our vision where “You make the game.” Let’s build.
