[counterintuitive] Are larger LLMs inherently safer and harder to jailbreak

Do not assume model size correlates with safety; apply independent, orthogonal guardrails \(input/output classifiers\) regardless of the base model size.

Journey Context:
It is assumed that more capable models are better at understanding safety rules. However, larger models are often \*more\* susceptible to subtle jailbreaks \(like many-shot or persona-based attacks\) because they follow instructions more rigorously, including malicious ones embedded in complex prompts. Their higher capability makes them a larger attack surface.
