What are AI agents?
AI agents are the next generation of intelligence. They move beyond analysis to independently act, adapt, and solve real-world problems – without the need for human intervention.
To have agency means to possess the ability to act independently and make choices. That, in a nutshell, is what differentiates an AI agent from the enterprise AI that is embedded in today’s best software solutions. Standard AI can analyse data, recognise patterns, and generate insights – but it’s still just an advisor, waiting for human action.
Agentic AI, on the other hand, builds upon these capabilities and applies them to self-direct actions in the real world. Where a traditional AI will work to give you the information you request so that you can make and execute decisions, AI agents can make and execute those decisions themselves.
AI agents explained
An AI agent is a type of artificial intelligence system that is capable of autonomously performing tasks and pursuing predefined goals. AI agents can problem-solve, make decisions, and execute actions without human intervention. They use large language models (LLMs) and natural language processing (NLP) techniques for a range of applications – from virtual assistants and complex analysis to robotics and self-driving cars. AI agents learn from their experiences and adapt their behaviours over time. They even work with other agents to coordinate and perform highly complex workflows.
Agentic AI vs. generative AI
Agentic AI and generative AI both offer huge productivity benefits, but they are not the same. Generative AI can create original content – such as text, images, or video – in response to a user’s prompt. Agentic AI, on the other hand, can autonomously make decisions, act, and pursue complex goals with limited human intervention. Generative AI is reactive to user input, whereas agentic AI is a proactive approach.
How do AI agents work?
An AI agent needs to be able to "see" its working environment in order to analyse it, create plans of action, and carry them out. As a sensory interface, the perception module gathers information from a range of sources, including sensors, linked apps, and direct user interactions.
1. Perception model
An AI agent must possess the ability to "observe" its operational surroundings in order to conduct analysis, formulate courses of action, and execute them accordingly. Functioning as a sensory interface, the perception module adeptly collects information from a diverse array of sources, comprising sensors, interconnected applications, and direct engagements with users.
2. Reasoning engine
After gathering data, the reasoning engine analyses trends, evaluates risks, and decides on the best course of action. Before acting, AI agents use algorithms to simulate outcomes and weigh several options.
3. Action execution
The execution phase follows immediately after determining the appropriate action. This involves putting decisions into action via workflow management, task automation, or direct physical device interaction.
4. Feedback loop
The feedback loop component keeps track of the outcomes and compares them to performance metrics and desired goals. If disparities are found, the agent can modify its future behaviour to facilitate better results down the road.

Risks in implementing AI agents
As AI agents become more autonomous, they bring a host of potential risks that organisations must carefully consider:
- Privacy concerns: To function at their best, AI agents often require access to sensitive data. This access raises significant privacy issues, especially if this data is transmitted to external servers. Keeping robust data protection measures in place is essential to maintaining trust.
- Ethical dilemmas: AI agents act on their own, and sometimes they make high-stakes decisions. It is crucial to maintain IT guardrails to they do not learn to prioritise efficiency over fairness, misinterpret ethical boundaries, or take actions that conflict with business ethics and values.
- Security vulnerabilities: Bad actors can exploit AI agents, manipulating them into making incorrect or even harmful decisions. Invest in comprehensive training for your teams, and ensure that your systems and solutions are using the best and most reliable cybersecurity measures.
- Agent and model drift: Over time, AI models may experience "model drift," where their performance degrades due to changes in input data patterns. Similarly, "agent drift" refers to AI agents deviating from their intended behaviour as they evolve and learn from new data. Again, it’s essential to prioritise team training and top quality cybersecurity.
