Overview
- Roblox unveiled Build on July 16 and says the feature will enter a public alpha on July 28 in New Zealand for age-checked users nine and older, with published Build games playable globally to users 16 and up after safety review.
- Build runs inside the Roblox mobile app and uses a mix of open-source and proprietary Roblox models trained on gaming-specific 3D data to generate gameplay mechanics, environments, characters, visual style, sound, and functional 3D scenes from plain-language prompts.
- Projects created in Build share the same back end, models, and chat history with Roblox Studio so creators can start on mobile and continue work on the desktop Studio tools.
- Roblox will offer a free basic tier and plans paid power-user options, and it is developing AI agents for playtesting, analytics, and experiment suggestions that the company says will roll out in the coming months.
- Industry outlets and developers warn that easier mobile generation could flood the catalog with repetitive or low-effort entries and raise moderation and discovery pressure, while Roblox says retention-based ranking will keep games that fail to hold players from rising in listings.
