AWS adds contextual grounding checks to Bedrock Guardrails

AWS announced contextual grounding checks and an ApplyGuardrail API for Amazon Bedrock Guardrails. The feature was described as a way to assess grounding and relevance for RAG and conversational applications, including use with custom and third-party foundation models, rather than a guarantee that an answer is true.

Engineering relevance

Guardrail scores are signals, not truth guarantees. Hypler should calibrate thresholds against real examples, preserve source and score evidence, and design safe behavior when a check is uncertain or unavailable.
