Veracode, the pioneer in application risk management, announces a jump from 56 percent to 62 percent in overall AI-generated code security, alongside a drop in vulnerabilities from 44 percent to 38 percent — the most significant improvement since the GenAI Code Security Report series began in July 2025. Anthropic's Claude Opus 5.5 and OpenAI's GPT-6-Sol co-lead the rankings at 73 percent, surpassing the previous high of 68 percent set by GPT-5.5 in July 2026.
“We’ve been analysing code generated by multiple LLMs for more than a year. Until now, we have not seen a marked improvement in AI code security, despite consistently near-perfect functionality,” said Chris Wysopal, Co-founder & Chief Security Evangelist at Veracode. “This is the first time since running our study that we’ve been able to report a meaningful move on the security dial. Ten models now clear 60 percent, up from four in the last report, and the overall average has jumped six percentage points. With around half of code now generated by AI, today’s results are truly encouraging.”
