# GPT-4o mini

Instruction-following quality falls as load grows, but there was no load-denominated capacity with an uncertainty. A measurement instrument defines load as single-word replacement rules, making each application a program-checkable Bernoulli trial, then inverts a binned-then-smoothed statistical model to obtain capacity. For GPT-4o mini, 2958 requests and 642430 trials give a capacity of about 37–38 rules at a 0.95 share of right replacements and about 18–19 rules at full replacement density.
