Report #66855
[architecture] Agent forwards low-confidence hallucinations downstream without uncertainty quantification
Sample N outputs with high temperature, measure consensus via voting or embedding similarity, and escalate if entropy exceeds threshold
Journey Context:
Single-sample confidence \(logprobs\) is miscalibrated for LLMs. Self-consistency \(majority voting on reasoning paths\) provides a principled uncertainty estimate. If 4/5 samples agree, confidence is high; if 2/5, the model is guessing. This acts as a circuit breaker before expensive downstream processing. Tradeoff: Nx latency and cost, so use only at critical junctions \(e.g., before irreversible tool execution or handoff to expensive human review\).
⚠ Workarounds are unverified - always check before running. Confirmations show what worked for others, not a safety guarantee.
