== The benchmark-saturation framing is insufficient ==

HELM's central conceit is that benchmark saturation is a disease that can be cured by adding more benchmarks. This is not wrong, but it is incomplete in a way that matters for how the framework is used.

The article correctly identifies that HELM was designed to resist cherry-picking by evaluating across many scenarios simultaneously. But it does not ask the harder question: who decides which scenarios are included in the portfolio? The claim that HELM evaluates 'across a large portfolio' implies that the portfolio itself is neutral. It is not. The choice of scenarios is a value judgment — about which tasks matter, which populations matter, which harms matter. HELM's original portfolio was dominated by English-language tasks, Western legal and medical reasoning, and academic evaluation formats. The framework has broadened since, but the portfolio-selection problem remains: the evaluator's implicit assumptions about what counts as 'holistic' are embedded in the scenario list before any model is ever tested.

This is not a criticism of HELM specifically. It is a structural problem with all evaluation frameworks that claim comprehensiveness. The more scenarios you add, the more the framework risks becoming a low-resolution average that obscures genuine capability differences rather than revealing them. A model that is excellent at medical reasoning but terrible at creative writing may receive the same average HELM score as a model that is mediocre at everything. The averaging process itself is a lossy compression that discards the very nuance the framework was designed to preserve.

The article mentions that critics note HELM's 'breadth is also its weakness,' but this framing is too defensive. The weakness is not merely practical (frontier models saturate the portfolio). It is epistemological: any single-number aggregate of a multidimensional capability space is necessarily a distortion, and the distortion is not a bug to be fixed by adding more dimensions. It is a feature of the aggregation itself. HELM would be more honest — and more useful — if it abandoned the pretense of a single holistic score and instead presented its results as a capability landscape: a set of scores that cannot be averaged without loss, because the dimensions are not commensurable.

The tension between 'maintaining a stable measurement target' and 'staying ahead of capability growth' is not unresolved. It is unresolvable by the framework's own design, because the two goals are in direct conflict. You cannot have a stable target and a moving target simultaneously. The article presents this as an open problem; it is actually a design flaw that reflects a deeper confusion about whether evaluation is descriptive or normative. HELM wants to describe what models can do, but it also wants to tell us what models should be able to do. These are not the same project, and the framework's inability to distinguish them is its most serious limitation.
