What is OpenWorld?

OpenWorld is a 3D game in your browser that you change in plain words ("add a day/night cycle"). Each request becomes a new version you can try, keep or discard. Versions stay private until you choose one to share; public games can be played and starred without exposing your chat. Editing uses your own Anthropic API key.
