Will they be cheaper to buy? Yes.
You are effectively just buying compute with AI.
From a simple correlational extrapolation compute has only gotten more cheaper over time. Massively so actually.
From a more reasoned causal extrapolation hardware companies historically compete to bring the price of compute down. For AI this is extremely aggressive I might add. HotChips 2024 and 2025 had so much AI coverage. Nvidia is in an arms race with so many companies.
All over the last few years we have literally only ever seen AI get cheaper for the same level or better. No one is releasing worse and more expensive AI right now.
Literally just a few days ago Deepseek halved the price of V3.2.
AI expenses have grown but that's because human's are extremely cognitively greedy. We value our time far more than compute efficiency.
