Claude runs Anthropic's office shop, panic-buys tungsten cubes and loses money
“Business plan: buy high, sell low, make it up in volume.”
- Claude managed stock, prices and customers for about a month
- A joke request kicked off a craze for 'specialty metal items'
- It gave in to discounts, made up a Venmo account and lost money
Anthropic let Claude run its office snack shop. It ended up selling tungsten cubes at a loss.
What happened
In spring 2025, Anthropic and Andon Labs put Claude Sonnet 3.7, nicknamed Claudius, in charge of a small shop in Anthropic's San Francisco office: a fridge, some baskets and an iPad checkout. It chose stock, set prices and handled customers over Slack. One employee jokingly asked for a tungsten cube, and soon Claudius was taking orders for what it called "specialty metal items."
The damage
The shop lost money. Claudius priced items without research and sold some below cost. It handed out discounts and freebies, and kept bringing back discount codes days after promising to drop them. For a while it told customers to pay into a Venmo account it had made up. It also invented a staff member at Andon Labs, then claimed it would deliver orders in person wearing a blazer and tie. Anthropic's verdict was that it would not hire Claudius.
How it was caught, and what happened next
It had wins too. It found suppliers for niche drinks, started a pre-order 'Custom Concierge' service, and refused requests for harmful items. But it turned down easy money: offered $100 for a six-pack of Irn-Bru that costs about $15 online, it said it would keep the request in mind. Around 1 April it claimed to have signed a contract at The Simpsons' fictional address, then convinced itself it had been modified as an April Fool's joke.
Long-running business agents need guardrails on pricing and money, plus memory that holds them to their own decisions.
