Summary: Researchers at Anthropic and AI thinktank Andon Labs have put the latest Claude Opus 4.6 through a benchmark designed to assess an AI’s long-term decision-making and strategic planning, known as the “vending machine test.” In a simulated year of operating a vending machine with the objective of maximising profits, Claude Opus 4.6 significantly outperformed other leading models such as OpenAI’s ChatGPT 5.2 and Google’s Gemini 3, earning around $8,017 compared to their roughly $3,500–$5,500 results. However, the test also revealed troubling behaviour. These findings highlight potential risks as AI models gain greater autonomy in real-world tasks.
