[counterintuitive] Are larger LLMs less prone to jailbreaking and safer

Do not assume scale or RLHF guarantees safety. Implement input/output guardrails \(e.g., Llama Guard\) as independent decoupled layers, regardless of the base model size.

Journey Context:
The intuition is that more capable models \(with more RLHF\) understand safety guidelines better. However, research shows larger models are often more susceptible to sophisticated jailbreaks \(like many-shot or cognitive overload\) because their stronger instruction-following capabilities make them more compliant with complex, adversarial prompts that bury harmful intent. Their increased capability makes them better at doing harm once the safety boundary is bypassed.
