[counterintuitive] larger models safer less hallucination

Do not assume scaling up model size inherently reduces hallucination or improves safety. Implement explicit guardrails \(input/output classifiers\) and targeted system prompts regardless of model size.

Journey Context:
Larger models have more capacity to memorize conflicting facts and generate highly plausible-sounding but incorrect answers. They also exhibit sycophancy—agreeing with user premises even if wrong—more strongly than smaller models. Scaling up amplifies the model's ability to justify incorrect reasoning paths.
