What Is an AI Agent? Everything You Need To Know

Artificial intelligence agents, or AI agents, are software programs that can act independently on your behalf. For instance, you can provide Lindy AI agents with data, such as meeting transcripts, content drafts, or customer queries. In just a few seconds, the agent can summarize meetings, create content, perform customer service, and more — essentially putting these processes on autopilot. 

By 2029, AI is projected to save professionals 12 hours per week in certain industries, which can significantly increase productivity. You can start reaping the benefits of AI agents today when you choose the right tools.

Let’s get started by learning what AI agents are.

What are AI agents?

An AI agent is essentially a software robot designed to perform specific jobs, kind of like a virtual employee. They're digital assistants that can understand complex commands and complete sophisticated tasks for you. The key thing that makes an AI agent smart is its ability to learn over time based on interactions and experiences. 

How AI agents work

AI agents operate by utilizing advanced machine learning algorithms and neural networks to analyze vast amounts of data, identify patterns, and make decisions or predictions without explicit human programming. 

For example, you can see how they work in this demo video of the Lindy AI Meeting Prep Assistant:

Let's dive deeper into how these intelligent agents work and adapt.

1. Data ingestion and preprocessing

The first step for any AI agent is to gather data from its environment. This data can come from various sources, such as user inputs, sensors, or databases. Before the AI can use this data, it needs to be cleaned and preprocessed. 

This involves:

2. Training the AI agent

Once the data is preprocessed, the AI agent undergoes training using large datasets to detect patterns and learn relationships between different data points. 

There are three primary methods through which AI agents learn:

3. Model building and deep learning

AI agents use deep learning, which involves neural networks — a series of algorithms that attempt to recognize relationships in a set of data through a process that mimics the human brain. 

Here’s how it works:

4. Decision-making process

Once trained, AI agents make decisions based on incoming data, using various strategies suited to their design. These strategies differ depending on how the agent is programmed to operate and the complexity of the tasks it needs to perform. 

For example, some agents rely on simple, rule-based approaches to respond to immediate stimuli, while others use internal models to predict outcomes before acting. Certain agents are designed to pursue specific goals and adjust their actions to reach those objectives effectively. 

Others evaluate multiple possible actions and select the one that offers the greatest overall benefit, balancing factors like speed, safety, or cost-efficiency.

In the coming section, we will explore these different decision-making methods in more detail, explaining how each type of agent chooses its actions and the advantages and limitations of each approach.

5. Continuous learning and adaptation

Many AI agents can continue to learn and adapt to new data after deployment, refining their models to improve performance over time. For example:

6. Deployment and integration

Once trained and tested, AI agents are deployed in their intended environment. They are integrated with existing systems or tools to start performing their tasks. For example:

7. Real-time monitoring and updates

AI agents require constant monitoring to ensure they perform correctly and efficiently. This involves:

Types of AI agents

Listen up because we’re about to give you the lowdown on all the main types of AI agents.

(One caveat: Several of these AI agent types can overlap, as is the case with utility-based and model-based agents in self-driving cars.)

1. Simple-reflex agents

Simple-reflex agents react to their environment using pre-set rules without learning or adapting from their actions.

How they work: These agents make decisions based solely on the current situation. They operate by using "if-then" rules, responding to specific inputs with predefined outputs without any memory of past events.

Here are some examples:

2. Goal-based agents

Goal-based agents are designed to achieve specific objectives by working step-by-step toward a goal.

How they work: These agents make decisions by evaluating which action will best help them achieve their defined goals. They are focused on long-term success but can struggle in unexpected situations.

Here are some examples:

3. Learning agents

Learning agents continuously improve by observing their environment and learning from their past actions.

How they work: These agents monitor their environment, experiment with different strategies, and adjust their behavior based on what works best. They learn from successes and mistakes to optimize future actions.

Here are some examples:

4. Model-based reflex agents

Model-based reflex agents use an internal model to make decisions based on how they perceive their environment.

How they work: These agents maintain a representation of their environment and use it to predict the outcomes of their actions. They react to the current state by referring to their internal model, which can be updated with new data.

Here are some examples:

5. Utility-based agents

Utility-based agents evaluate all possible actions and choose the one that maximizes their utility or usefulness.

How they work: These agents assess various potential actions and select the one that offers the highest value or chance of success, balancing multiple objectives to find the optimal outcome.

Here are some examples:

6. Multi-agent systems

Multi-agent systems consist of multiple AI agents working together to solve complex problems that a single agent cannot handle alone.

How they work: These agents collaborate by sharing information, dividing tasks based on specialization, and coordinating actions to achieve a common goal. Their interaction can result in emergent behavior, where simple rules lead to complex, coordinated outcomes.

Here are some examples:

And yes, you’ve guessed it: Lindy functions as a multi-agent system, enabling different AI agents to coordinate and share information to complete tasks more effectively.
