Shepherd's Dog: A Game by the Most Dangerous AI Model
Anthropic released a model deemed too dangerous. The author used it to create the game 'Shepherd's Dog' in one shot. The model spent 45 minutes and over €20 in tokens, producing a 2,319-line zero-dependency HTML game.
A few days ago, Anthropic released the model that was supposedly too dangerous for the world to see. I wanted to give it a try using my personal benchmark: can it build a game idea I've had for years, in a single shot?
The model started with a very long reasoning session, and after 45 minutes and more than €20 worth of tokens (!), it happily reported that "Shepherd's Dog is complete — a single 2,319 line index.html with zero dependencies."
You can watch the video below or give the game a try It's really fun and exactly how I imagined it. For me this is the first time an AI model is able to create this for me in one go:
