Hallucination Detection

AdvancedtestingMinimum 32K context

Designs checks that catch unsupported or fabricated claims in LLM output before users see them. Covers grounding verification against retrieved context, claim decomposition and per-claim entailment checking, citation validation, self-consistency sampling, and abstention thresholds, plus how to measure detector precision and recall on a labeled set.

Use cases

  • Verifying that RAG answers are grounded in retrieved passages
  • Decomposing an answer into claims and checking each for support
  • Validating that citations actually contain the cited statement
  • Setting abstention thresholds so the model says "I don't know"

Example prompt

Design a hallucination detection layer for our RAG assistant over internal documentation.

Cover:
1. How to decompose an answer into individually checkable claims
2. How to score each claim for support against the retrieved chunks
3. How to validate citations point at text that actually supports the claim
4. Thresholds for rewriting versus abstaining
5. How I measure detector precision and recall, and what labeled data I need

Include the implementation and note the latency and cost this adds per request.
