AI Safety: Why Compute Limits Won't Work as a Stopping Point for AI Development

scottleibrand · x · 2026-08-11

An AI safety researcher argues that if we need to establish a ceiling for AI development, the current approach of using compute metrics (such as maximum datacenter size or training FLOPS) will not be effective.

The primary reasons are twofold: first, rapid algorithmic progress will quickly lower the compute required to pose a threat; second, exploiting the spikiness of AI capabilities—such as ensuring AIs are disproportionately bad at long-horizon planning—cannot be reliably achieved through compute limits alone. The author suggests exploring alternative metrics to define a safe stopping point.
