What the article says around this equation
A vendor-reported score is a claim, not a fact, regardless of whether the model behind it is open or closed — that much does not change. What open weights add is a specific, bounded capability: the ability to fix as a checked, shared constant and then interrogate H until a gap is either explained or confirmed. The GSM8K and Artificial Analysis cases show that capability working exactly as intended, turning an apparent discrepancy into a diagnosed and closed procedural gap. The Llama 4 Maverick case shows what happens when the gap is not procedural: the same capability that resolves harness mismatches also has nowhere left to hide a genuinely different model, which is precisely why…

The Llama 4 Maverick case shows what happens when the gap is not procedural: the same capability that resolves harness mismatches also has nowhere left to hide a genuinely different model, which is precisely why that episode ended in a public correction rather than an unresolved dispute.
