Roblox is launching thumbnail personalization to help creators attract more users by showing the most relevant thumbnail to each user.

This is what Roblox Studio wants for its creators. The AI “does the boring stuff for them, and allows the creators to really think more about the abstract,” Corazza says.

Tens of millions of these games live on Roblox ’s browser—hundreds of times more titles than exist on Steam. Every day, 43 million people play those games, mostly kids.
