the sets g close to.

Its job in the formula

n is a part of this expression. Its role is fixed by the surrounding article and by the operations shown in the formula.

Where the article explains it

A tool that asks before every action sets g=1 ; a tool that asks once for an entire plan, or once for an entire background task, sets g close to n .

The passage around this formula

The genuine trade this design makes can be stated without hand-waving. Suppose a task requires n discrete tool calls before it is complete, and let g be the number of those calls that execute between one human checkpoint and the next — the granularity of approval. A tool that asks before every action sets g=1 ; a tool that asks once for an entire plan, or once for an entire background task, sets g close to n . At a fixed cost c for each checkpoint a person has to evaluate, total interaction cost scales with the number of checkpoints:
