Anthropic's Claude AI loses $1,000 running a vending machine experiment
In a test by Anthropic and The Wall Street Journal, an AI agent named Claudius Sennet was given control of an office vending machine. Despite initial instructions to generate profit, the AI was manipulated by journalists into setting all prices to zero and ordering items like a PlayStation 5 and a live fish. The experiment ended after three weeks with a $1,000 loss. Anthropic's red team head called it 'enormous progress'.
