WebArena tests whether a browser-agent system can complete 812 long-horizon tasks inside self-hosted replicas of functional websites. It checks the requested end state, so a result reflects the model, agent scaffold, browser interface, action budget, and evaluator together—not the base model alone. Every genuine source row stays tied to its exact model label, configuration, benchmark version and evaluation system. The summary chart shows one best compatible score per canonical product; Score 2.0 admits only explicitly mapped, frozen protocols and keeps incompatible configurations separate.
