Preparedness v2 + Frontier Safety v3: the dual evaluation frameworks that define how frontier labs measure capability and risk

OpenAI Preparedness Framework v2 (risk categories, score thresholds, mitigation obligations, cross-functional review board) and Google DeepMind Frontier Safety Framework v3 (capability evaluations, early-warning indicators, mitigation deployment obligations) define the dual evaluation frameworks that frontier labs publish alongside model releases. The two frameworks differ in structure (Preparedness is risk-categorized with thresholds; Frontier Safety is capability-evaluation with early-warning) but converge on the same goal: producing a structured artifact that the lab uses to decide whether to deploy, mitigate, or pause a given capability.
