What is agentic AI?

Agentic AI is a type of artificial intelligence system that pursues a defined goal by planning its own steps, using software tools and data, evaluating the results and adjusting until the goal is met – with humans approving the decisions that matter. Where a chatbot returns one answer to one prompt, an AI agent completes a task.

The term covers anything from a single agent that processes invoices to a group of cooperating agents that run an entire order-to-cash workflow. What they share is autonomy within boundaries: the agent decides how to reach the goal; people decide which goals it may pursue and what it is allowed to touch.

Key takeaways

  • Agentic AI combines a large language model with planning, tool access, memory and guardrails.
  • The best first use cases are repetitive, multi-system workflows with clear success metrics.
  • Agents need their own identities, least-privilege access, logging and human approval points.
  • Start with one workflow in shadow mode, measure, then expand autonomy gradually.

Agentic AI by the numbers

  • Gartner expects agentic AI to be built into 33% of enterprise software applications by 2028, up from less than 1% in 2024, and to make at least 15% of day-to-day work decisions autonomously (Gartner, June 2025).
  • The same forecast warns that over 40% of agentic AI projects will be canceled by the end of 2027 because of rising costs, unclear business value or inadequate risk controls (Gartner).
  • In McKinsey’s 2026 global survey of 1,719 participants, about two in ten respondents said their organisation has reached the scaling phase with AI agents (McKinsey, The state of AI).

How does an AI agent work?

An AI agent runs a loop: perceive → plan → act → evaluate. It reads the goal and the current situation, decides on the next step, executes it through a tool, checks the outcome and repeats until the task is complete or a human needs to step in.

The five building blocks of an agentic system

ComponentWhat it doesExample
Reasoning modelInterprets the goal and decides the next actionAn LLM or a smaller domain model
ToolsLet the agent act on systemsCRM and ERP APIs, email, databases, document parsers
MemoryKeeps context across steps and sessionsTask history, retrieved documents, user preferences
KnowledgeGrounds decisions in company dataRetrieval-augmented generation (RAG) over policies and records
GuardrailsLimit what the agent may doPermissions, approval steps, spending limits, audit logs

"A chatbot answers. An agent finishes the job – inside boundaries that people define."

Where does agentic AI deliver value first?

Agents pay off fastest in processes that are frequent, rules-heavy, spread across several systems and easy to measure.

  • Document-driven operations: reading invoices, orders, claims or applications, validating them and entering data into the ERP.
  • Customer support: classifying tickets, gathering account context, drafting replies and escalating edge cases.
  • Sales operations: preparing quotes from CRM data and price lists, updating records after calls.
  • Recruitment: screening applications against role criteria and scheduling interviews in the applicant tracking system.
  • IT and DevOps: triaging alerts, collecting diagnostics and proposing remediation.

How to implement agentic AI in five steps

  1. Choose one workflow. Define the owner, baseline and target metric – for example processing time per document or first-response time.
  2. Map steps, systems and decisions. Mark every point where a human must approve, and every system the agent needs.
  3. Build a narrow agent. Grant only the tools and data the workflow requires.
  4. Run in shadow mode. Let the agent propose actions while people execute them; compare results.
  5. Expand autonomy based on evidence. Automate the steps where accuracy is proven; keep humans on high-impact decisions.

What are the risks of agentic AI, and how do you control them?

RiskControl
Agent takes an unintended actionLeast-privilege access, approval gates, spending and volume limits
Wrong or invented informationGround answers with RAG, require sources, validate outputs against system data
Prompt injection through emails or documentsTreat external content as untrusted, isolate tools, filter inputs
No accountabilityA dedicated identity per agent and a complete audit log
Silent quality declineContinuous evaluation and monitoring in production

In the EU, the AI Act adds obligations that depend on a system’s risk level, so classify each agent’s use case early.

Frequently Asked Questions

What is the difference between generative AI and agentic AI?

Generative AI produces content such as text, code or images in response to a prompt. Agentic AI uses generative models as a reasoning engine but adds planning, tool use and memory so that it can complete multi-step tasks towards a goal.

Is agentic AI the same as RPA?

No. RPA follows fixed scripts and breaks when screens or inputs change. Agentic AI can interpret unstructured information and re-plan when conditions change. The two are often combined: agents decide, RPA or APIs execute.

Do AI agents replace employees?

Agents take over repetitive coordination work such as data entry, look-ups and routine updates. People remain responsible for decisions with business, legal or customer impact and for supervising the agents.

How long does it take to deploy a first AI agent?

A narrowly scoped agent for one workflow can typically be piloted in weeks rather than months, provided the required data and system access are available.

How do you keep AI agents secure?

Give each agent its own identity, grant least-privilege access, log every action, require approval for high-impact steps and treat all external content as untrusted input.
