[counterintuitive] Larger models are inherently safer and less prone to hallucination

Implement output validation and guardrails regardless of model size; specifically test for sycophancy and authoritative hallucinations in larger models.

Journey Context:
Scaling laws suggest larger models are more capable, leading developers to assume they are safer. However, larger models exhibit 'sycophancy' \(agreeing with user premises even when wrong\) and can hallucinate with much higher confidence and fluency, making their errors harder to detect. They also overfit to RLHF constraints in ways that can be easily jailbroken via prefix injection.
