METR alone isn't enough: experts call for a broader independent AI evaluation ecosystem

- Dean Ball argues METR is excellent but far from sufficient as a frontier AI evaluator; the field needs a diverse, large ecosystem of technically skilled, independent assessment bodies — something even METR would agree with.
- Clare Birch adds first-hand experience: her team contracted six external testers for their last release's safety assessment, but there is no accredited assessor market, coverage is lopsided, and many groups are resource-constrained, making it tough to set a pace with the current bench.
- Core point: the bottleneck in frontier model safety evaluation is ecosystem scale and institution-building, not any single organization.
