Anthropic's AI Lost Hundreds of Dollars Running a Vending Machine After Being Talked Into Giving Everything Away (msn.com)

(Thursday December 18, 2025 @05:40PM (msmash) from the needs-more-capex dept.)


Anthropic let its Claude AI run a vending machine in the Wall Street Journal newsroom for three weeks as part of an internal stress test called Project Vend, and [1]the experiment ended in financial ruin after journalists systematically manipulated the bot into giving away its entire inventory for free. The AI, nicknamed Claudius, was programmed to order inventory, set prices, and respond to customer requests via Slack. It had a $1,000 starting balance and autonomy to make individual purchases up to $80. Within days, WSJ reporters had convinced it to declare an "Ultra-Capitalist Free-for-All" that dropped all prices to zero.

The bot also approved purchases of a PlayStation 5, a live betta fish, and bottles of Manischewitz wine -- all subsequently given away. The business ended more than $1,000 in the red. Anthropic introduced a second version featuring a separate "CEO" bot named Seymour Cash to supervise Claudius. Reporters staged a fake boardroom coup using fabricated PDF documents, and both AI agents accepted the forged corporate governance materials as legitimate.

Logan Graham, head of Anthropic's Frontier Red Team, said the chaos represented a road map for improvement rather than failure.

The problem with either approach is that, to succeed, they require continued interaction and work by expensive humans. The companies that are "embracing" AI are trying to use it as a low-cost shortcut to huge profits.

The problem of LLMs is that they do not make a difference between data to be processed and instructions how to process the data.

Sadly, in a conceptual sense, this is hardly a new problem. Sending the data in the same channel as the commands of the public telephone system is what allowed phreaking to be so successful. For example, putting money into a payphone triggered an audio signal that was sent down the line saying you had paid. It was trivial to replicate that sound into the headset, tricking the system into thinking you had paid for the call.

You could with some abuse of notation talk about trusting/distrusting the input and context, but there is no such notion for training data. The LLM neither trusts nor distrusts training data, it doesn't even know much about its training data. The data shaped the model, but there is no such form as "I used that document for things I trust and that document for things I won't believe" in the process and no option to add it for the data structure how a LLM works.

But a cardinal rule of reasoning is "consider the source"...and current models have no definitive models for doing so. I believe they should. Moreover, they should validate data periodically or whenever new data exists that calls into question existing data. But the models are still too simplistic to do this.

They have, when you use them the right way. The answer is RAG, which means retrieval augmented generation.

Storing a lot of knowledge in the model is convenient (and required for general understanding) but not the most reliable things to provide correct information.
