Most AI Agents Aren't Really Agents At All

Summary

The current discourse surrounding "AI agents" often mislabels many sophisticated LLM-powered systems as true agents, when they are more accurately described as "agentic systems" – powerful, human-engineered workflows wrapped around large language models. Drawing from the "Critique of Agent Model" paper, the distinction is made between agentic systems, which complete tasks via external control loops, and agentive systems, which derive behavior from internal structures like persistent goals, adaptive identity, and self-regulation. The paper introduces a five-dimension framework (Goal, Identity, Decision-making, Self-regulation, Learning) to evaluate true agency, noting that most current LLM systems fall short of being fully agentive. It also advocates for separating the "world model" (for prediction) from the "agent model" (for action) to enhance clarity and debugging.

Key takeaway

For AI Engineers and Architects designing LLM-powered systems, recognize that most "AI agents" are currently agentic pipelines. You should evaluate your systems against the five dimensions of agency: Goal, Identity, Decision-making, Self-regulation, and Learning. This distinction helps you honestly label your creations and focus development on internalizing more agentive capabilities, moving beyond simple tool-calling loops. Consider building systems that evolve self-models and regulate their own reasoning depth.

Key insights

Most "AI agents" are agentic workflows, not truly agentive systems with internal goals, identity, and self-regulation.

Principles

• Agentic systems use engineered workflows; agentive systems internalize behavior.
• True agency involves Goal, Identity, Decision-making, Self-regulation, Learning.
• World models predict; agent models decide actions.

In practice

• Use the five agency dimensions to evaluate system capabilities.
• Implement self-models to track system strengths, weaknesses, and policies.

Topics

• AI Agents
