Agentic AI describes a system built to pursue a goal by planning steps, making decisions, using tools, and carrying out a multi-step workflow with some degree of autonomy. The two are not rival technologies. An agentic system often uses a generative model to read a request and produce content, while the software around that model decides what happens next.
What generative AI does
Generative AI is defined by its output. Given a prompt or other input, a generative model returns new or transformed material: text, images, audio, video, code, or a summary of a document. The user typically gives an instruction, receives a result, and decides what to do with it. IBM’s comparison describes generative AI as content-focused, and that framing is a useful test: if the main job is to create, summarize, or reshape content, the system is doing generative work even if it is very sophisticated.

A generative model on its own usually responds to a prompt and then waits. It does not, by itself, check a calendar, open a ticket, or decide to try a second approach after the first one fails.

What makes agentic AI different
Agentic AI is defined by its purpose and its behavior over time. An agentic system is designed to pursue a goal, not just answer a single request. It can break that goal into steps, choose which tools to call, evaluate what came back, and decide whether to continue, change course, or stop. IBM describes agentic AI as goal-focused, and notes that it may draw on the same underlying techniques as generative AI, including machine learning, language models, and natural-language processing.
The key shift is from a single response to a sequence of actions. The user may specify an outcome, such as “get this vendor invoice reconciled,” rather than each individual step.
Side-by-side comparison
| Dimension | Generative AI | Agentic AI |
|---|---|---|
| Main purpose | Create, summarize, or transform content from a prompt or other input. | Pursue a goal through decisions and, often, multi-step workflows. |
| Typical interaction | The user gives an instruction and reviews the returned content. | The user may state an outcome; the system determines steps and continues through the workflow. |
| Output | Text, images, audio, video, code, summaries, or transformed content. | Progress toward a goal, which may include generated content, retrieved information, decisions, or actions in other systems. |
| Tools and external systems | Depends on what tools are built around the model; a model alone does not reach outside systems. | Tool, database, API, or application use is commonly part of completing the task. |
| Autonomy and oversight | Usually responds to a prompt and waits for the next direction. | Varies by design; a system can run several steps while people keep approval points and oversight. Not stated as fully autonomous in the cited sources. |
What makes a system agentic
Whether a product is agentic depends on the system around the model, not on the model alone. Across the sources reviewed, the recurring design elements are:
- An objective the system works toward, rather than a single question to answer.
- A planning loop that breaks the objective into steps and decides which step comes next.
- Tool selection and calls to APIs, databases, or applications.
- State or memory, so earlier results inform later steps.
- Evaluation of what happened after each action, so the system can adjust.
- Escalation, where the system asks a person for help or approval when it cannot proceed safely.
A system with a generative model and none of these elements is generative AI in the ordinary sense. Adding a chatbot interface to a model does not make the product agentic.

NIST describes the current agent paradigm as general-purpose AI models combined with software scaffolding that lets the model manipulate tools and act beyond simple text output. That scaffolding is where most of the agentic behavior lives.
How the two work together
In many real systems, the two are layered. The generative model interprets the request, drafts text, or writes code. The agentic layer decides which steps are needed, retrieves information, invokes tools, checks intermediate results, and determines whether to continue or request approval.
Consider an event invitation. Drafting the invitation text is generative work. Checking calendars, reserving a room, tracking replies, and updating the attendee list is a multi-step workflow, and a generative model may be one component inside that agentic workflow. This is an illustrative example of how the parts fit together, not a claim about how any particular product performs.
How to decide which one a task needs
Start with the job, then check the risk.
- Is the task one content response or a sequence of actions? A draft, summary, or code suggestion for human review is generative. A task that requires pursuing an outcome over several steps points toward an agentic design.
- Does the system only offer information, or can it read from or write to external services? Write access turns a text answer into a potential change in another system.
- Which decisions can it make without a person, and where does it pause? Map each decision point explicitly.
- Could an action have side effects that are hard to reverse? Sending a message, changing a record, or making a payment deserves a different level of control than generating a draft.
- Can the actions be monitored and audited? If you cannot see what the system did, you cannot reliably correct it.
- Which actions require review or explicit approval? Write these down before deployment, not after an incident.
NIST’s discussion of tool use names access patterns, risk, reliability, modality, monitoring, and autonomy as useful dimensions for comparing agent tools. The steps above follow the same logic in plainer terms.

An agent can create consequences beyond the content of its answer once it can act on external systems. Microsoft’s Azure guidance distinguishes prompt-to-response interaction from goal-to-autonomous-multi-step action, and identifies risks that matter specifically for agents:
- Prompt injection that steers the system into taking actions it should not take.
- Excessive agency, where a system holds more permissions than its task requires.
- Confused-deputy behavior, where the agent uses its own elevated access on behalf of a party that should not have that access.
The controls Microsoft recommends include least-privilege tool permissions, authorization for each action, audit logs, limits on steps and costs, and human approval gates for high-impact or irreversible actions. Microsoft also highlights agent identity, memory, and additional trust boundaries as security considerations.
Avoid describing every agent as fully autonomous. NIST’s description emphasizes autonomous-agent characteristics, but IBM states that the degree of autonomy depends on system design and oversight, and that people may approve actions or supply judgment. In practice, most deployed agentic systems sit somewhere between a suggestion engine and a fully unattended process.
What the sources do and do not settle
There is no single, binding, universal definition of “agentic AI.” The descriptions above are current working definitions from NIST, IBM, and Microsoft, and they agree on observable behavior: goal pursuit, multi-step action, tool use, and oversight. Treat any sharp boundary between “generative” and “agentic” as a design choice for a specific system rather than a settled classification.
NIST’s August 5, 2025 article reports that approximately 140 experts took part in an AI Safety Institute Consortium workshop held in January, hosted by NIST’s Center for AI Standards and Innovation (CAISI) and the Consortium. The article does not name the experts or attribute particular views to individuals, so the figure describes participation only.
NIST’s agentic AI overview states that the agency “promotes U.S. innovation and cultivates trust in agentic AI by focusing on trustworthiness, evaluation/testing, standards, interoperability, governance, and risk management.” That is an institutional statement, not a quotation from a named person. The NIST overview page did not display a publication date when reviewed, so check its current version before citing it.
