[frontier] How do I reduce hallucination risk when an AI agent makes high-stakes irreversible decisions?

Implement cross-model consensus: for critical decision nodes, query 3\+ heterogeneous models \(e.g., Claude 3.5 Sonnet, GPT-4o, Gemini 1.5 Pro\), require majority agreement on the action and parameters, and trigger human escalation on dissent.

Journey Context:
Single-model reliance creates single points of failure; ensemble methods \(like LLM-as-a-judge\) usually compare outputs rather than enforce consensus. The 'swarm verification' pattern \(emerging from multi-agent safety research and Anthropic's Collective Constitutional AI work\) treats model disagreement as a circuit breaker. The tradeoff is latency \(3x inference cost\) and cost, but for irreversible actions \(deletion, financial transactions, deployment\), this beats the alternative of hallucinated tool calls. The key insight is using heterogeneous models \(different architectures/training data\) to minimize correlated errors—if Claude and GPT disagree, it's likely a true ambiguity, not a shared hallucination.
