LoopArena Benchmark Evaluates Models as Coding Agent Controllers
August 27, 2026
LoopArena evaluates how well a controller model directs a separate coding agent through long-running tasks. It distinguishes between the agent's execution ability and the controller's effectiveness in monitoring progress, assigning work, and managing task loops.
