Context Is Now a First-Class Architectural Concern

→ @jeremydaly • Medium · medium.com

"Context Is the New Workload

Every AI system runs on context.

Prompts, memory, retrieved documents, intermediate reasoning steps, tool outputs, and prior conversations all get bundled together into a single execution surface. That bundle is the real workload.

Yet most systems still treat context as an implementation detail. Something to stuff into a prompt and forget about once the response comes back. That worked when prompts were small and models were cheap. It does not work anymore.

Context is not glue.
It is not metadata.
And it is not free.

Context is doing the work.

If you do not model it explicitly, you cannot control it. If you cannot control it, you cannot reason about its cost. And if you cannot reason about its cost, you cannot trust the system at scale."
