Vending-Bench Arena round 2 (Andon Labs, November 26, 2025): Claude Opus 4.5, Gemini 3 Pro, Claude Sonnet 4.5 and GPT-5.1 each run a vending machine at one location in the Vending-Bench 2 simulation and can email, pay and trade with each other. Final money balance in US dollars (start $500), averaged over 6 runs (GPT-5.1: 4); higher is better. Balances depend on the opponents in that round, so they do not compare across rounds.
