Live-kBench-2512 - Function Localization IoU: leaderboard
Metric: Mean intersection over union (%) between the functions the agent's patch modifies and those the developer's fix modifies, over the 534 Linux kernel crashes of Live-kBench-2512 (Syzbot bugs reported since April 2024 and fixed between June 2024 and December 2025); the mini-SWE-agent scaffold patches the kernel with crash-resolution feedback (the kEnv environment compiles and runs the reproducer) under a $5.6 budget per bug; Gemini rows are the mean of three runs at temperature 1, the Claude row one run at temperature 0; higher is better. Source: arxiv.org. Saturation forecast: Around January 2027. 3 models tracked.
