At this year's AIE World’s Fair, AI engineering entered a new phase: building systems around agents, rather than just building with agents. The conference highlighted five major trends: the shift from agents to their surrounding systems, loop engineering as a new control layer, enterprise adoption via forward deployed engineers, coding agents replacing IDEs as the primary interface, and the rise of skills in agent platforms.
The focus has shifted from autonomous agents to the systems that manage workflows, context, and evaluation.
Loop engineering, with inner and outer loops, provides oversight for increasingly autonomous agents.
