SEC-bench Pro - Linux: leaderboard

SEC-bench Pro tests AI agents on finding vulnerabilities and writing working proof-of-concept inputs for real open-source code, each instance run in a Docker harness and confirmed by a checker. This board covers the Linux target, added in June 2026: percent of its instances solved, timeouts counted as failures. Rows are agent, model and effort runs; the site withholds newer Claude Opus and Mythos results. Higher is better.

Metric: Linux instances solved, headline mode (% of 137 instances; timeouts count as unsolved). Source: sec-bench.github.io. Saturation forecast: Around February 2027. 6 models tracked.
