Roblox just unveiled Build, a mobile-first AI creation tab inside its app that lets anyone generate playable 3D games directly from plain text prompts without writing code. The tool automates mechanics, environments, characters, and audio using proprietary 3D gaming models. It launches a free public alpha in New Zealand on July 28, with professional testing and analytics agents coming to Studio soon.
Roblox just brought agentic AI workflows to Roblox Studio and Assistant to automate the entire plan, build, and test loop. The update adds a collaborative Planning Mode, text-to-mesh generation, and a beta playtesting agent that controls characters to test games. Studio also baked in an MCP server to plug directly into Cursor and Claude.
Roblox just launched a beta for 4D generation powered by its Cube foundation model, adding real-time interactivity to 3D objects. Using modular schemas, players can type a prompt to spawn a multi-part car and immediately drive it around. Early tests in community games saw player time jump 64%.
Roblox is testing two new generative AI tools for Roblox Studio that turn natural language prompts into 3D materials and working code. The goal is to let creators jump straight into world-building even if they lack 3D modeling skills or coding experience. Both features will roll out to Roblox Studio developers in the coming weeks.
