Safety
Grounding
The practice of anchoring AI outputs in verifiable external data sources (documents, databases, search results) to reduce hallucination and improve factual accuracy.
Explained at five levels
Level 1
Making sure the AI's answers are based on real facts, not just stuff it made up.
Level 2
Connecting AI responses to real, verified information sources — like search results or documents — so answers are factual instead of invented.
Level 3
The practice of anchoring AI outputs in verifiable external data sources (documents, databases, search results) to reduce hallucination and improve factual accuracy.
Level 4
Conditioning model generation on retrieved evidence or structured knowledge to ensure outputs are faithful to source material — a key technique for reducing confabulation in production systems.
Level 5
Establishing a causal information pathway from verified external sources to generated tokens, ensuring semantic faithfulness via retrieval conditioning, citation generation, and attribution verification — quantifiable through groundedness metrics and source-attribution F1.
