Report #71243

[counterintuitive] Are larger LLMs inherently safer and less prone to harmful outputs

Do not assume scaling replaces safety guardrails. Implement strict input/output validation and guardrails regardless of model size, as larger models can be more capable of circumventing their own safety training.

Journey Context:
There is a belief that bigger models undergo more RLHF and thus are 'safer.' While they might refuse more basic harmful prompts, their increased capability makes them better at following complex, adversarial instructions that bypass safety filters. A small model might fail to synthesize dangerous content; a large model might know the content and be clever enough to bypass the RLHF refusal under a multi-turn prompt.
