Perhaps the 85 tokens only account for a mutable suffix e.g. date/time/location, with a longer but more cacheable prefix being unbilled.

I tried asking it "what time is it?" and got back:

> I don't have access to real-time information, so I can't tell you the current time. Your device's clock (on your phone, computer, or watch) will show you the accurate time for your location.

> Is there something else I can help you with?
