Sounds to me like your problem has shifted from how much the AI tool costs per hour to how much it costs per token because resetting a model happens often enough that the price doesn't amortize out per hour. That giant spike every ?? months overshadows the average cost per day.

I wonder if this will become more universal, and if we won't see a 'tick-tock' pattern like Intel used, where they tweak the existing architecture one or more times between major design work. The 'tick' is about keeping you competitive and the 'tock' is about keeping you relevant.
