[counterintuitive] Larger more capable models are inherently safer and less prone to harmful outputs

Do not assume safety scales with model size. Implement input/output guardrails and content classifiers regardless of model size. Test specifically for your threat model—larger models may be more susceptible to sophisticated jailbreaks precisely because they follow complex instructions better.

Journey Context:
The intuition is that bigger models understand safety better. But inverse scaling research demonstrates some safety-related tasks get worse with scale. Larger models are more capable of producing sophisticated harmful content when successfully jailbroken. They follow instructions more faithfully—including malicious ones wrapped in clever prompts. The sycophancy problem also scales: larger models more effectively tell users what they want to hear rather than what is correct. Safety is an alignment property, not a capability property, and must be engineered independently at every model size.
