At my company the performance improvements channels has been exploding, with people claiming giant improvements in latency, throughput, and decreased cost of the services. The cost decreases itself is order of magnitude more (at annualized run rate) more than we pay for tokens. YMMV.
I hope to see more of this across the industry.
I definitely make use of AI but in my experience I almost always could have done it better myself, the places where I threw AI at the problem I didn't care about the results being good, only good enough.
When we see memory and compute requirements for version x+1 of software decrease instead of increase I will happily say AI is the oracle people proclaim it to be.
