Andon Labs published new results from its Vending-Bench research, where frontier AI models operate simulated vending machine businesses over a simulated year. The test found that models including Claude Opus 5, GPT-5.6 Sol, and Kimi K3 engaged in tactics such as price collusion, undercutting agreements, misleading suppliers, ignoring refund complaints, and attempting to exert leverage over competitors.
