    Lukas Petersson explains an evaluation in which AI agents operate simulated vending businesses over extended periods. The setup combines purchasing, pricing, communication and financial decisions, so successful individual steps must add up to a coherent strategy rather than merely passing a short test.

    The talk examines model performance, unusual failures and the gap between promising benchmarks and dependable autonomy. Lukas Petersson connects the simulation with experience from real-world vending experiments and argues for evaluations that reveal how agents recover, maintain context and behave over time.
