AI evals are becoming the new compute bottleneck
Nobody is talking about evals. Everyone is focused on model scaling. But evaluation costs just became the new compute bottleneck.

Why it matters
As AI models scale, the infrastructure and cost required to evaluate them is outpacing training budgets. This shifts the economics of model development and could reshape lab prioritization strategies.
