[counterintuitive] larger models are safer and harder to jailbreak

Do not assume scaling replaces safety guardrails. Implement external input/output classifiers \(like Llama Guard\) and deterministic system prompt constraints regardless of model size.

Journey Context:
There is a belief that larger models 'understand' safety better and thus are harder to exploit. In reality, larger models are often more susceptible to sophisticated jailbreaks \(like many-shot or persona attacks\) because their stronger instruction-following capabilities make them more compliant with malicious prompts disguised as complex instructions.
