SecRepoBench asks code agents to complete a masked region of a function in 318 tasks from 27 C/C++ repositories covering 15 CWEs, with the whole repository available and web search disabled. Models here run inside the Aider agent framework. Secure-pass@1 is the percent of completions that pass the unit tests and survive the OSS-Fuzz proof-of-concept exploit; higher is better.

Metric: Completions that pass the unit tests and the PoC security test, pass@1 (%). Source: secrepobench.github.io. Saturation forecast: Around August 2027. 7 models tracked.
