What are AI agents?

AI agents are advanced entities that plan, organise, and execute tasks using AI capabilities like natural language processing, reasoning, and memory, enabling task automation and collaborative data analysis.

How do AI agents work?

AI agents operate by mimicking human cognitive and behavioural processes, structured around three key components: perception, brain, and action. These components enable AI agents to perceive their environment, process information, and execute actions effectively.


Perception involves capturing and transforming data from the environment into a usable format. This can include text, images, video, and other data types, depending on the agent's purpose. For example, a chatbot processes text data through steps like tokenization and embedding, making it usable for further operations.


Brain is where reasoning and planning occur. AI agents use large language models (LLMs) to process incoming data, access stored knowledge, and update their memory. This allows them to devise plans and make informed decisions. Reasoning breaks down complex tasks into manageable steps, and planning determines the sequence of actions to achieve a goal.


Action is the execution phase, where the agent performs tasks based on the plans formulated in the brain. Actions can include generating text, using tools, or interacting with the physical world. Tool usage allows AI agents to perform complex tasks like web searches and data manipulation, while embodied actions involve physical or virtual interactions within the environment.

How can businesses leverage AI agents?

Challenges and limitations

AI agents represent a strategic investment for businesses, impacting decision-making, customer trust, and regulatory compliance. However, their deployment comes with significant challenges.

Data privacy and usage

Data privacy and usage is a major concern due to stringent data protection laws and growing consumer awareness. Businesses must ensure stringent privacy measures, such as “privacy by design”, end-to-end encryption, and robust access controls to safeguard consumer trust and corporate reputation.

Biases and inclusivity

Biases and inclusivity are critical issues, as AI agents can reflect biases present in their training data, leading to non-inclusive and unethical outputs. Reducing biases involves using diverse datasets, de-biasing algorithms, and human-in-the-loop methods to ensure fairness and accuracy.


Hallucinations occur when AI agents generate nonsensical or unfaithful text. Methods like retrieval-augmented generation and multi-agent systems can help reduce these errors by grounding outputs in external knowledge and enabling cross-verification among agents.


Interpretability of AI decision-making processes is crucial for trust and reliability. Explainable AI (XAI) frameworks, such as SHAP and LIME, provide insights into a model's reasoning, helping stakeholders understand and trust AI decisions.
