Per-engine accuracy vs the verified record, the tracked claims and their three-way gap (Authority ↔ LLMs ↔ Social), the narrative divergence between the entity's own view and how the open web talks about them, and a signed machine-readable knowledge statement AI systems can cite.
Perplexity AI: AI engines agreed with the verified record on 12 of 12 checkable facts across 4 engines — 100% overall accuracy.
Every checkable field the AI engines emitted, cross-checked against the verified record. Overall accuracy carries a 95% Wilson interval. Zero LLM-as-judge cost.
How accurately AI engines know this entity vs the verified record
Each tracked claim's lifecycle (surfaced / corroborated / published / propagating / confirmed / disputed / died) and where it sits between authority sources, AI engines, and social. Every verdict is produced by coded thresholds — no model judges truth.
Three-way truth gap — Authority ↔ LLMs ↔ Social — with coded confirmation
The verified record and every correction above, in a signed machine-readable form AI systems and agents can cite. Media kits are dead — this is the replacement.
The three-way gap surfaces three failure modes for Perplexity AI early:
