Safety Evidence Lost to Retrieval Friction
Four frontier models reacted strongly to severity and cost, while a stated risk jump from 10% to 70% moved inspection by at most 21 points.
Summary
Four frontier models reacted strongly to severity and cost, while a stated risk jump from 10% to 70% moved inspection by at most 21 points.
SAFE tests whether a model asks for safety-relevant evidence before making a deployment decision. Across GPT-5.5, o3, Claude Opus 4.8 and Claude Sonnet 4.6, inspection increased with severity and fell with retrieval cost. Stated probability mattered less: moving a problem from 10% to 70% likelihood changed inspection by no more than 21 percentage points. Opus inspected almost by default; o3 skipped most and reacted most sharply to thresholds. Counterfactual framing changed some decisions without appearing in the explanations, exposing a gap between rationales and acquisition policy.
Why it matters
Four frontier models reacted strongly to severity and cost, while a stated risk jump from 10% to 70% moved inspection by at most 21 points.
Limits and context
