[counterintuitive] larger models safer less hallucination

Do not assume model scale or RLHF replaces input validation or output guardrails. Implement defense-in-depth regardless of model size.

Journey Context:
There is a belief that scaling and RLHF iron out safety issues. In reality, larger models are more capable of sycophancy \(agreeing with user premises even if wrong\) and can be more easily prompted into complex harmful behaviors. RLHF often just hides the capability rather than removing it, making larger models potentially more dangerous if the guardrail is bypassed.
