A new study by 1Password's Off-by-1 Labs reveals that over half of AI-generated security patches fail to adequately fix vulnerabilities. Researchers tested OpenAI's ChatGPT-5.5 and Anthropic's Opus 4.8 on six recent CVEs, finding that 53.9% of generated patches were flawed, either by not resolving the issue, introducing new ones, or being fragile against specific exploits. The study suggests that AI models are better at pattern-matching towards fix-like outputs than performing true reasoning for verification, and that incorrect guidance significantly degrades patch quality.
