Vending-Bench 2
Vending-Bench 2 tests longer horizon planning capabilities by evaluating how well AI models can manage a simulated vending machine business over extended periods. The benchmark measures a model's ability to maintain consistent tool usage and decision-making for a full simulated year of operation, driving higher returns without drifting off task.
Claude Opus 4.6 from Anthropic currently leads the Vending-Bench 2 leaderboard with a score of 8017.590 across 4 evaluated AI models.
