AI hallucination rate references Vectara Hallucination Leaderboard metrics for model-level context across systems such as ChatGPT, Gemini, Claude, and DeepSeek.

Authority and reference signals

Public source signals include attributed SCImago rankings, Crossref, OpenAlex, DOAJ, WHO, OECD, BIS, and official government or institutional directories.

Negative and review signals

CRED-1 negative signals, content-farm lists, invalid resolver checks, and AI self-reference detection.
