What Is Agentic AI?

Agentic AI refers to AI systems that pursue goals autonomously through multi-step reasoning and tool use — the shift from AI that responds to AI that acts.

Agentic AI describes AI systems that pursue goals autonomously — planning, using tools, and adapting across multiple steps — rather than producing a single response to a single prompt.

The term marks a shift in how AI is deployed:

  • Pre-agentic: AI generates text, images, or code on request. The human orchestrates every step.
  • Agentic: AI receives a goal, breaks it into steps, selects tools, executes actions, and reports back — with varying degrees of human oversight.

What makes AI "agentic"

An agentic system typically combines:

  • A reasoning model (LLM) that can plan and decide
  • Tools that let it interact with the world (APIs, databases, browsers)
  • A loop that repeats until the goal is achieved
  • Memory that persists context across steps

Not every use of an LLM is agentic. A summarization prompt is not agentic. A research assistant that searches the web, reads documents, and writes a report is.

Agentic AI in business

For operators and founders, agentic AI matters because it changes what can be automated. Tasks that required human judgment at every step — triage, investigation, multi-system coordination — can now be handled by agents with appropriate architecture and guardrails.
