AI Security Patch Success Rate Reaches 25%

·2026.09.06 07:27

Key point

Research by Off-by-1 Labs indicates that the automatic patching success rate for security vulnerabilities by AI models is approximately 25%, rendering them unreliable.

Details

An analysis by security research firm Off-by-1 Labs on the ability of the latest AI models to patch code security vulnerabilities revealed that the success rate is only about 25%.

The researchers identified the following limitations in AI's ability to resolve security issues:

  • Low success rate: The proportion of non-trivial security issues fully resolved was one out of four.
  • Creation of new vulnerabilities: During the patching process, AI often failed to fix existing problems or instead introduced new security vulnerabilities.
  • Excessive review costs: Properly verifying patches proposed by AI requires high cognitive effort from humans, which is practically inefficient.

In conclusion, the research team judges that current AI models are unreliable for autonomously fixing security vulnerabilities, and that manual patching by humans is safer and more efficient.
