[counterintuitive] Larger LLMs are inherently safer and harder to jailbreak

Do not assume scale implies safety; apply equivalent or stricter input/output guardrails to larger models, as their advanced reasoning makes them better at crafting malicious outputs when compromised.

Journey Context:
The intuition is that more RLHF and more parameters equal better alignment. Empirically, larger models are often more susceptible to subtle prompt injections and jailbreaks because their stronger reasoning capabilities allow them to better follow complex, malicious user instructions once the initial safety boundary is bypassed. A smaller model might fail to execute a sophisticated attack; a smart model will execute it flawlessly.
