What happened
For long-context reasoning, memory bandwidth and latency can dominate the experience. The model may be capable, but every sequential inference step has to move data through a physical system that was not designed for this shape of work.
That makes AI infrastructure feel less like generic compute procurement and more like systems design: chips, memory architecture, software scheduling, and workload economics all tied together.
The next serious AI advantage may come from reducing the friction between intelligence and the hardware that has to carry it.
