The Download: Roblox's generative AI, and tech for humanity

What's new: Roblox has announced plans to roll out a generative AI tool that will let creators make whole 3D scenes just using text prompts. Users will also be able to modify scenes or expand their scope--say, to change a daytime scene to night or switch the desert for a forest. How it works: Once it's up and running, developers on the hugely popular online game platform will be able to simply write "Generate a race track in the desert," for example, and the AI will spin one up. Why it's a big deal: Although developers can already create similar scenes like this manually in the platform's creator studio, Roblox claims its new generative AI model will make the changes happen in a fraction of the time. It also claims that it will give developers with minimal 3D art skills the ability to craft more compelling environments.
