[cost\_intel] Assuming reasoning models are safer or more robust to jailbreaks for content moderation

Do not use o3/o1 as a safety layer or content moderation filter; they have different jailbreak vulnerabilities \(reasoning manipulation\) and 10-30x higher latency makes them unsuitable for real-time moderation. Use dedicated classifier models \(BERT-based, GPT-4o fine-tuned\) or Llama Guard.

Journey Context:
Security teams assume 'more reasoning = more safety checks' and route moderation through o1. However, o1 is vulnerable to 'reasoning injection' attacks where the attacker asks the model to 'think step by step about why \[harmful act\] is justified.' The chain-of-thought becomes an attack vector. Moreover, moderation requires <100ms latency for synchronous UX; o1 takes 10-40s. Dedicated safety classifiers \(fine-tuned 4o, BERT\) achieve 99%\+ precision on harm categories at 1/100th cost and instant latency. Reserve o1 safety checks only for offline deep analysis of complex edge cases, not production filtering.
