According to initial reports on social media, the recently released Claude 3 Opus is capable of generating coherent code for entire applications. Developer Murat Ayfer shows an impressive demo: He lets Claude 3 generate a multi-user drawing application in the browser with a single prompt on the first try. Ayfer used the following prompt: "Make a multiplayer drawing app where the strokes appear on everyone else's screens in realtime. let user pick a name and color. save users to db on login." If you want to test the app, you can find the code here.
