AI-driven constraint reasoning

Why Codex Security Doesn't Include a SAST Report

OpenAI explains the design rationale behind Codex Security's approach to vulnerability detection, which forgoes traditional Static Application Security Testing (SAST) in favor of AI-driven constraint reasoning and validation. The post argues this approach surfaces real vulnerabilities while reducing false positives compared to conventional static analysis tools. This represents a substantive technical position on how LLM-based code analysis differs from rule-based security scanning.
