This might entirely be true but I'm hoping that's because the frontier models are just actually more expensive to run as well.

Said another way, I would hope, the price of GPT-5.5 falls significantly in a year when GPT-5.8 is out.

Someone else on this post commented:

Having used Kimi-2.6, it can go on for hours spewing nonsense. I personally am happy to pay 10x the price of something that doesn't help me, for something else that does, in even half the time.
