Usage plunges on the weekends and during the summer, suggesting that a significant portion of users are students using ChatGPT for free or at heavily subsidized rates to do homework (i.e., extremely basic work that is extraordinarily well-represented in the training data). That usage will almost certainly never be monetizable, and it suggests nothing about the trajectory of the technology’s capability or popularity. I suspect ChatGPT, in particular, will see its usage slip considerably as the education system (hopefully) adapts.
