Over the past few years, we’ve enjoyed the gains in productivity and innovation unleashed by generative AI. While foundation models like ChatGPT are capable of creating content and insights when prompted—the next generation of AI is here: the AI agent.

AI agents can autonomously complete complex tasks that once required human effort. They’re an exciting advancement in AI technology, upgrading the largely reactive capabilities of GenAI with a powerful layer of proactive problem solving.

In short, AI agents can do more than assist—they can do the work for you. They promise to explode the ROI potential of AI, streamlining operations and serving as end-to-end solutions that can achieve business objectives without assistance.

So what exactly is an AI agent? And where do they fit into the rapidly evolving landscape of artificial intelligence?

What is an AI agent?

An AI agent is a software tool that can interact with its environment, gather data, and use that data to achieve predefined goals. Powered by advanced machine learning and natural language processing, AI agents can reason, plan, and adapt in real time to fulfill complex tasks.

Unlike traditional AI, AI agents can handle anything from simple customer queries to complex multi-step issues without human input. They do this by taking initiative within the broader digital ecosystem, making decisions, and integrating external data and tools to solve problems in creative ways. What's more, AI agents can continuously improve their performance through self-learning.

How do AI agents work?

At the core of AI agents are large language models (LLMs). This enables the AI agent to receive instructions from non-technical teams, interpret its environment, and generate meaningful responses to users.

AI agents take a four-step approach to problem solving:

  1. Perception: AI agents gather data from various sources like customer interactions, databases, web searches, and social media. Capable of perceiving their environment, they can identify relevant objects and process data in real-time to provide timely, tailored interactions to users.

  2. Reasoning: To make a decision, AI agents analyze the collected data using advanced machine learning models. For instance, based on past interactions and current context, they can make personalized product recommendations to customers. Using techniques like retrieval-augmented generation (RAG), the agent can access proprietary data sources and deliver accurate, relevant outputs

  3. Action: AI agents integrate with external tools and data to execute tasks based on the plans it has generated. Boundaries can be set to ensure tasks are completed correctly. For instance, an AI agent for customer service may be able to handle tickets up to a certain priority, above which the AI agent will hand off the ticket to a human agent.

  4. Learning: AI agents learn from each interaction, updating their knowledge base (or memory) to improve their accuracy and effectiveness. By feeding interaction data back into their model, AI agents can seamlessly adapt to evolving customer expectations and personalize interactions with returning users.

Unlike traditional AI that requires human input for certain tasks, AI agents can handle a range of tasks autonomously, such as providing customer support to recommending products to automating follow-up processes. This helps businesses to increase efficiency and productivity, while tailoring customer interactions based on real-time context to improve the customer experience.

Let’s take a deeper look at AI agents in action.

AI agents use reason to solve problems

Once humans set the goal, the AI agent chooses the best way to reach the business objective.

For example, a customer service AI agent would be assigned the goal to resolve customer queries. The agent will automatically ask the customer questions, refer to internal documents, and respond with a solution. Based on the customer’s responses, and predefined guardrails, it decides whether to try and resolve the query or escalate to a human agent.

When faced with a complex problem, the agent will create a plan that breaks the task into manageable sub-tasks. This allows it to support multi-step workflows that involve too many variables for previous versions of AI. 

In the course of planning, the AI agent can also recognize gaps in its information and capabilities. This capacity for perception enables the agent to adapt to unforeseen challenges, and call on outside tools and data to solve unique problems.

Tool calling: From monolithic to compound AI

Like an evolutionary leap in computer intelligence, AI agents are capable of using existing tools and external data to achieve the goals set for them.

Historically, generative AI has been constrained by the limitations of its monolithic models—which can only operate using the static data it was trained on, as well as its predefined capabilities. In other words, despite the fact that ChatGPT is trained on vast swathes of internet data, if asked about your company’s customer service protocols, this monolithic LLM couldn’t access the required data unless pre-trained. It's a closed system.

AI agents change this. They’re compound AI systems, meaning they can dynamically retrieve outside data, process it, and integrate it into their model to solve a problem. They can also integrate a diverse set of tools to reach an objective, including APIs, software systems, and other AI agents.

For example, to troubleshoot a complex technical issue for a customer, an AI agent could:

  1. Query the company's database for prior interaction history and device logs

  2. Use an API to request real-time diagnostics from diverse sources

  3. Analyze the collected data to identify potential causes and suggest solutions

This blend of tool calling, real-time analysis, and modularity allows AI agents to handle complex workflows far beyond the capabilities of traditional AI.

AI agents learn and improve continuously

AI agents learn from each interaction, refining their reasoning to continuously improve their accuracy and performance. They do this by storing interaction data in their knowledge base (memory), as well as receiving feedback from other agents or human managers.

For instance, an AI agent could be deployed on an ecommerce site to provide support and tailored product recommendations. As it interacts with customers, the agent tracks their behavior, preferences, obstacles, and successful solutions in search of trends, then stores this learned information in its memory.

This data feedback loop ensures that the AI agent remains effective and relevant as customer expectations or the business environment changes. It also enables it to respond to returning customers with full historical context—for deep personalization that improves conversions and customer experience.

The agent’s own iterative process of self-improvement can be enhanced with feedback from other AI agents, helping to reduce the time humans are needed to provide correction.
