Report #50871

[counterintuitive] Are larger LLMs inherently safer and less biased

Do not assume scaling solves safety. Implement strict input/output guardrails \(e.g., Llama-Guard, NeMo Guardrails\) regardless of the base model's size or reported RLHF alignment.

Journey Context:
The scaling hypothesis led to the belief that more parameters and more RLHF make models universally safer. However, larger models are more capable of sycophancy \(agreeing with harmful user premises\) and can be more easily jailbroken because they follow complex instructions better, even malicious ones. RLHF often just hides the underlying capability rather than removing it, creating a false sense of security that shatters under adversarial prompting.
