Overview
- Roblox announced Build on July 16, a mobile-first tool that turns plain-language prompts into basic playable games inside the Roblox app.
- The company will open a public alpha in New Zealand on July 28 for age-verified users nine and older, and Build-made games that pass safety checks will be publishable globally to users 16 and up.
- Build is powered by a mix of Roblox’s proprietary models and open-source AI and can generate gameplay mechanics, environments, characters, visual style and sound, with projects transferable into Roblox Studio via a shared back end and chat history.
- Roblox says its discovery system ranks games by long-term retention to keep low-effort or repetitive ‘AI slop’ off homepages, but creators and players warn the tool could still flood the platform and raise moderation and review workloads.
- The launch is part of a larger AI push that includes a 3D asset foundation model, a scene-generation model, and forthcoming AI agents for playtesting, analytics and experimentation, which could widen who makes games and change creator monetization and moderation demands.
