CVerifBench: leaderboard

We introduce an evaluation framework of 500 C verification tasks across five property types (memory safety, overflow, termination, reachability, data races) built on SV-COMP 2025, and evaluate 14 models across six families. We find that high overall accuracy masks a critical weakness: while most models reliably confirm properties hold, violation detection varies widely and degrades sharply with pr

Metric: Total (self-reported). Source: benchmarklist.com. Saturation forecast: Around June 2027. 14 models tracked.
