2026 GenAI Code Security Report
Is Code Written by AI Safe to Ship?
AI-generated code volume has exploded, but the failure rate hasn’t decreased. In the 2026 GenAI Code Security Report, Veracode tests new models across 80 tasks so security and engineering leaders can make AI tooling decisions with actual data behind them.
What You Will Learn:
The Leaderboard
Every model we tested, ranked by security pass rate. See which models produce the most secure code, where the ceiling sits, where the floor sits, and how the field is separating.
Language-Level Findings
Security performance varies dramatically by language. One language in our dataset lags the others by dozens of percentage points. We show where each language sits, which are improving, and which are stuck.
CWE-by-CWE Breakdown
Not all vulnerability classes move at the same rate. Some are climbing. Others are flat. We break down performance by CWE category so you can see exactly where models are getting better and where they’re not.
