Report #40318

[cost\_intel] When does the 10x cost and 30s latency of o1 pay off for security vulnerability detection in CI/CD?

Use o1 only for deep static analysis of security-critical modules \(crypto, auth\) in nightly builds; use GPT-4o for fast incremental linting. o1 finds 30-40% more true positives on CWE-Top-25 with 50% fewer false positives than GPT-4o, justifying the cost for audit-gated releases.

Journey Context:
Security scanning has a bimodal distribution: simple pattern matching \(SQLi from string concat\) versus complex taint analysis \(multi-hop data flow\). GPT-4o misses vulnerabilities requiring reasoning across function boundaries \(e.g., 'this user input flows through a sanitizer but the regex is bypassable'\). o1's deliberative search finds these. However, 30s latency blocks CI/CD feedback loops. Deploy o1 in nightly deep scans while using 4o for fast incremental checks. Degradation signature: 4o produces high false positive rate on complex taint analysis, creating alert fatigue.
