LoopArena - Task Slice: leaderboard
Metric: Strict success rate (%; 27 task slices paired with the full tasks (Type II); the evaluated model is the Controller: after each round it reads a Reporter's evidence packet and issues the next instruction to, or stops, a fixed Qwen3.7-Plus coding Worker, which alone has coding tools; a run succeeds only when it passes the task evaluator (every Core check for SCBench, reward 1 from the official Harbor evaluator for BeyondSWE) and follows the control protocol; three runs per task; provider-default reasoning). Source: arxiv.org. Saturation forecast: Around August 2027. 5 models tracked.
