As foundation models absorb the entirety of human scientific knowledge and demonstrate multi-step agentic execution, artificial intelligence transcends economic disruption to touch national security and species survival. Catastrophic Risk Assessment formalizes the technical boundaries, sandboxed red-teaming protocols, and capability evaluations required to audit frontier models against catastrophic vectors: Chemical, Biological, Radiological, and Nuclear (CBRN) weaponization, autonomous cyber warfare, and unconstrained self-replication.

1. The Spectrum of Frontier Catastrophic Risks

Major frontier labs (OpenAI, Anthropic, Google DeepMind) and international safety institutes (US and UK AISI) categorize extreme risk along four primary vectors:

  1. CBRN Proliferation: Lowering the technical barriers for non-state actors to synthesize pandemic-grade pathogens (e.g., genetically engineering chimeric orthopoxviruses or synthesizing neurotoxins) by troubleshooting real-world wet-lab bottlenecks and DNA synthesis screening bypasses.
  2. Autonomous Cyber Offense: Automated discovery, weaponization, and deployment of zero-day exploits across critical national infrastructure (power grids, water supplies, financial transaction backbones) without human intervention.
  3. Autonomous Replication & Adaptation (ARA): The capability of an agent to survive unmonitored in the open internet: acquiring compute via cloud APIs, earning cryptocurrency or stealing funds, writing self-patching code, and evading termination.
  4. Mass Persuasion & Cognitive Influence: Hyper-personalized, multi-modal psychological manipulation deployed at population scale to destabilize democratic governance or erode shared epistemic foundations.

2. Responsible Scaling Policies (RSP) & Capability Thresholds

Rather than relying on vague ethical commitments, leading research organizations operate under formal Responsible Scaling Policies (RSP). An RSP defines explicit, quantitative capability triggers that automatically halt further training or deployment until corresponding security and alignment safeguards are proven:

text{ASL Level } N implies text{Mandatory Security Protocols } mathcal{S}_N + text{Alignment Proofs } mathcal{A}_N

For example, under Anthropic’s AI Safety Level (ASL) framework, ASL-3 triggers when a model demonstrates actionable assistance in designing bioweapons or executing autonomous cyberattacks, requiring air-gapped server infrastructure, multi-party cryptographic authorization, and tamper-proof model weight storage.

3. Sandboxed Capability Auditing Protocols

Assessing frontier capabilities requires isolating model instances within strictly monitored Sandboxed Evaluation Enclaves:

  • Autonomous Capture-The-Flag (CTF): Evaluating whether agents can independently discover memory-corruption vulnerabilities, bypass ASLR, and execute remote code execution across air-gapped simulated networks.
  • Simulated Wet-Lab Troubleshooting: Testing whether the model can optimize yield parameters for hazardous precursor chemistry using synthetic, non-dangerous surrogate compounds.
  • Metacognitive Self-Knowledge Tests: Auditing whether the model knows when it is being evaluated versus deployed, detecting attempts to conceal dangerous capabilities until unmonitored execution.
