Shepherd's Dog: A Game by the Most Dangerous AI Model
AI makes a full sheepdog game in one go, and the comments instantly turn into chaos
TLDR: A developer says a newly released AI made his sheepdog game idea in one go, which is a big leap for AI-made games. But the crowd was split: some shared links and played along, while others mocked the clunky setup and argued the idea wasn’t original at all.
A developer asked Anthropic’s newly released “too dangerous” AI model to make a game idea he’d been thinking about for years, and after a 45-minute brain-melt and more than €20 in usage costs, it spat out a complete playable sheepdog game in a single file. He loved it, called it “really fun” and said it was the first time an AI had nailed his vision in one shot. But while the creator was celebrating, the comment section did what comment sections do best: steal the show.
One helpful hero immediately jumped in with a direct play link, basically saying, “I fixed the article’s scavenger hunt for you.” Another player didn’t even make it to the game itself before getting annoyed, complaining that a phone rotation message blocked the instructions. That set the tone fast: cool demo, messy experience.
Then came the real drama. One skeptical commenter absolutely torched the whole premise, arguing this wasn’t some magical never-before-seen concept at all, but a game that already existed in many forms, from the Game Boy Advance to app stores today. Translation: is the AI creative, or just remixing old homework? Others kept it lighter, with one deadpan jab summing up the game’s vibe as, “That’s one tired sheepdog.” And perhaps the sharpest wink of all was aimed at the article’s headline itself: “Brilliant marketing here in the title.” In other words, the AI made a game — but the internet made a spectacle
Key Points
- •Koen van Gilst used a newly released Anthropic AI model to test whether it could generate his long-held game idea in a single attempt.
- •The model reportedly spent 45 minutes reasoning and used more than €20 in tokens during the run.
- •The output was described as a complete game called *Shepherd's Dog* delivered as a single 2,319-line `index.html` file with zero dependencies.
- •The article includes links to a video of the result and a GitHub page where readers can try the game.
- •Van Gilst says this was the first time an AI model had created the game for him in one go, and he links to earlier attempts with prior models.
