What the story wants you to believe
That Opus 5 belongs in the highest echelon of AI models — not because of measurable outcomes, but because it approximates an elite, internally defined standard.
What it makes harder to question
Whether Opus 5’s actual performance justifies premium pricing, enterprise adoption, or regulatory deference — since the comparison bypasses objective benchmarks.
How the spin works
