Four Walls Constrain AI Today. We’re Breaking Them All.

Just 16 months ago, I wrote about AI outgrowing the server. While this thesis holds, the workloads have changed: The challenges then were defined by the size of training clusters, but AI now has entered the inference era in earnest.The hottest topic among data center operators is no longer the “AI model” but the “AI factory” – and the winning approach must deliver not just peak… Read more

AI Infra Summit 2026: When You Can’t Buy More Memory, You Get More Out of What You Have

Squeezing More Out of Every ByteGoogle Fellow Dave Patterson had the line of AI Infra Summit 2026: We’re entering a “memory-centric era.” The pricing backs him up. Analyst Jim Handy of Objective Analysis tells us that DRAM average price increased 250% from 2Q25 to 2Q26. Businesses are slowing down because they simply cannot get enough of it.But everyone walked into the summit… Read more
