💬 Customer Support Bot frontier
As of October 25, 2026, the highest Customer Support Bot score on this frontier is Gemini 4 Argon at 100.0, with an estimated monthly cost of $367.50.
A high-volume B2C chatbot. We weight Arena (human preference) and IFEval (does it follow your formatting instructions?) heavily, and lean on cost because volume is enormous. Reliability axes (format-adherence, safety-handling) are weighted modestly because a chatbot that answers off-format or false-refuses on benign requests is unusable regardless of how smart it is.
The y axis is this scenario's weighted score; the x axis starts at estimated monthly cost for 5,000 requests a day. Switch axes to compare against speed, latency or context. See the full ranking.
