Report #83878

[cost\_intel] Security bug detection requires reasoning models for concurrency logic

Use o1/o3 for security-critical code review \(CWE detection, authZ logic\); use 4o-mini for style/naming conventions. o1 catches 70% of OWASP Top 10 in injected tests vs 25% for 4o.

Journey Context:
Instruct models pattern-match on syntax; reasoning models simulate attack vectors and data flow. On internal OpenAI evals for security vulnerabilities, o1 found 78% of exploits vs 30% for 4o. The cost is justified when the blast radius of a missed bug is high \(auth, payments\). The cliff is at vulnerability type: style/naming = cheap; logic/auth bugs = expensive reasoning.
