The relevant question is “how incidental/baseline to life is this expense?”

We require clothes for on-site interviews. We require phone service for phone screens and electricity and internet service for video interviews. We don’t pay gas/mileage for on-site interviews for local candidates. People think of those as incidental/de minimus expenses and we ignore them.

I think LLM subs are going to be just as baseline as mobile phone service very soon (far, far faster than mobile phone adoption was in the US or Europe).
