This is thoroughly debunked at this point. The frontier labs are profitable on the tokens they serve. They are negative when you bake in the training costs for the next generation.
So what. Fluctuations over a year or two are meaningless. Do you really believe that the constant-dollar price of an LLM token will be higher in 20 years?
I can see a world where energy costs rise at a rate faster than overall inflation, or are a leading indicator. In that scenario then yes I could see LLM token costs going up.
