LoopsBench - Claude Code Loop - Test Pass Rate: leaderboard
LoopsBench (arXiv 2608.00267v2, Table 2 model sweep): eight models from different vendors on 112 dependency-structured long-horizon coding tasks, all run in the Claude Code loop. Mean fraction of released tests passing at task end after outer-loop continuation; percent, higher is better.
Metric: Released-test pass rate (%; with outer-loop continuation). Source: arxiv.org. Saturation forecast: Around May 2027. 8 models tracked.
