[cost\_intel] Using reasoning models for high-volume content moderation at scale

Use fine-tuned GPT-4o-mini moderation classifier \($0.0006/req\) vs o3-mini \($0.003/req\); reserve reasoning models for adversarial jailbreak analysis and novel policy edge cases only

Journey Context:
Moderation requires low latency and clear policy rules, not deep reasoning. Fine-tuned 4o-mini reaches 99% accuracy on standard moderation sets vs o3-mini at 99.5% but 5x cost and 10x latency. The failure mode of cheap models is edge cases \(sarcasm, context-dependent slurs, novel jailbreaks\). Cost-per-flag shows reasoning models only justified when handling <0.1% adversarial traffic, not bulk filtering.
