Three Levels of Agentic Engineering: The Real Bottleneck is Compute, Not LLMs

peterjliu · x · 2026-08-13

The author categorizes current Agentic Engineering into three evolutionary levels:

Level 1: Limited by local personal computers or a single max-tier AI subscription.
Level 2: Transitioning to APIs or multiple subscriptions, running agents 24/7 on remote machines.
Level 3: Single machines run out of memory or CPU, making the number of accessible remote machines the new limiting factor.

The author concludes that as agent engineering advances, the real bottleneck becomes the compute power to run agents, not the LLMs themselves.
