Arena says OpenAI models hold six of 11 Agent Arena Pareto frontier spots
Overview
Arena says OpenAI's GPT-6 Luna and GPT-6.1 Sol hold six of the 11 spots on its Agent Arena Pareto frontier across their reasoning efforts.
Arena says GPT-6 Luna takes three of the four frontier spots below $0.10 per task, using Max, Medium and Low reasoning. Arena says GPT-6.1 Sol sets the frontier between $0.22 and $0.65 per task, with the same three reasoning levels on it. Arena adds that GPT-6 Astra (Max) is also on the frontier, which would give OpenAI seven of the 11 spots.
