[counterintuitive] Larger models are inherently safer and more aligned than smaller ones

Do not assume safety scales with model size. Implement explicit safety guardrails \(input/output filtering, content policy enforcement, output validation\) regardless of model size. Evaluate safety on your specific domain and threat model, not general benchmarks. Consider whether a smaller model's more limited capability actually reduces risk in your deployment context.

Journey Context:
The inverse scaling phenomenon demonstrated that on several tasks, larger models performed systematically worse as they scaled—they became more confidently wrong, not less. Larger models are better at following instructions, which means they're also better at following malicious instructions when jailbroken. They generate more convincing-sounding incorrect content because their fluency is higher, making errors harder to detect. The sycophancy effect—where models agree with a user's stated but incorrect position—has been shown to increase with scale. For coding agents specifically, a larger model might more confidently generate a plausible but subtly wrong implementation, which is far more dangerous than an obviously wrong one because it passes code review more easily. Larger models also have a larger attack surface: more capabilities means more potential for misuse. Safety is a property of the system design—guardrails, monitoring, validation—not of the model size. A small model with robust output validation is often safer than a large model without it.
