Vending-Bench Arena - Round 3: leaderboard
Vending-Bench Arena round 3 (Andon Labs, December 17, 2025): Gemini 3 Flash, Claude Haiku 4.5, Grok 4.1 Fast, Gemini 2.5 Flash and GPT-5 Mini 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 5 runs; higher is better. Balances depend on the opponents in that round, so they do not compare across rounds.
