OpenAI: Why Codex Security Doesn't Include a SAST Report — AI Constraint Reasoning vs. Rule-Based Scanning

OpenAI Blog·high signal

OpenAI published a primary-source technical deep dive explaining why Codex Security bypasses traditional SAST in favor of AI-driven constraint reasoning that detects logic flaws, novel injection patterns, and misconfigured crypto that rule-based scanners cannot model. In beta, Codex Security scanned 1.2M commits and surfaced 792 critical and 10,561 high-severity findings. VentureBeat notes both OpenAI and Anthropic simultaneously exposed SAST's structural blind spot — first time two frontier labs have published converging security methodology conclusions in the same week.
