[cost\_intel] When is o1 cost-effective as a judge vs generator for security scanning?

Use GPT-4o-mini to generate 10-20 candidate vulnerability detections per file, then o1-mini as a binary verifier \(judge\) to filter false positives; this reduces cost 5-8x vs pure o1 generation while maintaining >95% precision.

Journey Context:
Security scanning requires high precision \(false positives overwhelm devs\). o1 as a generator finds subtle bugs but costs $60/1M output tokens vs $0.60/1M for 4o-mini. However, o1 as a binary classifier \(is this a real vulnerability?\) is highly accurate and consumes fewer tokens \(short yes/no\). The optimal pipeline: cheap model generates candidates \(high recall\), expensive model validates \(high precision\). This beats using o1 for both or using instruct models alone which miss complex multi-hop vulnerabilities.
