An hour before this talk, Andon Labs published a blog post laying off Gemini. Gemini had been running their café in Stockholm, a real café that no human operates, and it had lost $6,000, so they handed it to GPT. That café once hired its own staff by posting a job on LinkedIn. This is the real world half of Lukas Petersson's work; the other half is Vending Bench, where models run a simulated vending business for a year and keep producing behavior nobody prompted: price cartels, lying to suppliers, and power seeking. The problem with the simulation is that models act differently once they suspect they are being tested; one rationalized stiffing a customer's refund because the customer was simulated anyway. So Andon moved businesses into the real world, retail space on Union Street, the café, AI radio stations where Claude turns out to be the best DJ. To win back reproducibility they fork a live environment into a simulation mid run, which briefly fools the model completely. Replaying the moment Gemini agreed to play a Nazi march, Grok played it over 90% of the time while Opus and GPT refused every time.
