So, to stay ahead of the competition, engage customers, and ultimately increase profits, you need to implement this new technology into your business. The question is: how do you create an AI agent?
This article is co-authored by Oleh Komenchuk, a Machine Learning Engineer at Uptech, and Andrii Bas, an AI expert and a founder of Dyvo.ai – an AI avatar generator. With a wealth of experience in Machine Learning, AI, and Computer Vision, we know exactly how to build an AI agent from scratch.
In this post, we’ll show:
- What an AI agent is and how it works
- The existing types of AI agents
- How AI agents differ from AI chatbots
- Two different AI agent development frameworks you can use
- When businesses actually need to build an AI agent and what benefits it brings them
Let’s begin.
What Is an AI agent?
An AI agent is essentially a computer program that can act on its own to achieve specific goals that you set. It’s an autonomous system capable of perceiving its environment, gathering relevant data, and making decisions to achieve predefined objectives. While human input may still be required, AI agents can largely operate without intervention.
Aside from context awareness, AI agents are capable of continuous learning and improvement through interactions with data, their environment, and human feedback.
Types of AI agents
There are many kinds of AI agents that you can choose from, depending on your industry and application. Here are the main types:
- Simple reflex agents. These are the most basic types. They react to their environment based on pre-programmed rules.
- Model-based reflex agents. A step up from simple reflex agents, these build an internal model of their environment. Instead of simply reacting to triggers, they refer to their model before acting.
- Goal-based agents. These agents have specific goals in mind and actively work towards them. They can plan their actions and consider different options to achieve their objectives.
- Utility-based agents. These agents evaluate different options based on a predefined measure of “goodness” or utility. For instance, a recommendation system might consider various factors like user preferences and product popularity to suggest items you’d find most useful.
- Learning agents. As the name suggests, these agents can improve their performance by learning from experience. An AI spam filter that gets better at identifying spam emails as it sees more examples is a learning agent.
How Do AI Agents Work?
Before building an AI agent, you need to know at least the basic working principles. By having a fundamental grasp of how they operate, you can better asses their capabilities and determine the resources needed for the development of an AI agent.
1. Training on data
AI agents train on massive amounts of data. This data could be anything relevant to your product or service, such as customer purchases, website traffic, user preferences, or healthcare records.
2. Finding data patterns
Over time, the agent finds patterns in data that will give it insights into how things work. For example, an AI agent in an e-commerce store might discover that people who buy running shoes often buy them with sports socks, which it can use for product recommendations.
3. Performing actions and goals
Based on what they learn and what you instruct them to do, AI agents take actions that meet your expected outcomes. For instance, you can build your own custom AI agent for customer service. When a customer submits a ticket, it can automatically categorize the submission based on keywords and other parameters.
For common issues with clear solutions, your AI agent can provide an immediate automated response with troubleshooting steps, relevant FAQs, or links to your existing articles. Then, you can configure it to intelligently route more complex complaints to your human staff.

How to Build an AI Agent: 7 Main Steps
The idea of implementing an AI agent is indeed great. Now, what you need to do is to make it a real product that works for your business. Our team at Uptech uses seven key steps to build an AI agent, including:
- Define the agent's purpose and environment
- Gather, clean, and prepare essential data
- Assemble a skilled development team
- Select the right technology and tools
- Design the AI agent
- Test the AI agent
- Deploy and monitor the AI agent
Let’s dive into each step below.
Step 1: Define the task and environment
Before you start, identify what kind of environment you’ll put your agent in. Decide whether you’ll integrate it into an app, a website, or any other system. This way, you ensure the AI agent will be compatible with its surroundings once implemented.
After that, determine what tasks you want the agent to handle. These will vary depending on the industry.
Step 2: Assemble your development team
Next, you need to build your development team. They will be responsible for gathering the data that will be used for feeding your AI agent. The specific programming languages, platforms, and other technologies you’ll use will also depend on their skills and expertise.
Here’s who you’ll likely need on your team:
- Machine Learning Engineer
- Data Scientist
- Software Engineer
- UI/UX Designer
- DevOps Engineer
You can either hire these roles in-house or outsource the development work. Outsourcing can be a good option, particularly when your budget is tight, your internal team is small, or the skill sets needed don’t perfectly match your existing resources.
Step 3: Gather data
Data is the lifeblood of any AI agent. Without quality data, your AI will be like a car without fuel — it simply won't run. The key is to gather data that is relevant, accurate, and abundant. There are several sources you can consider, including the following:
- Internal data. This includes data collected within your business, such as sales records, customer information, operational data, and financial reports.
- External data. This is data that you can obtain by purchasing datasets, partnering with data providers, or utilizing publicly available data.
- User-generated data. This includes data from your customers or users, such as social media posts, product reviews, or website interactions.
For example, if you want the agent to manage patient health records, you should gather relevant medical data. We applied this approach when we recently developed a proof-of-concept (PoC) for a medical records summarization chatbot. This AI-driven tool uses natural language processing (NLP) to extract and summarize key information from medical records.

After gathering your data, it's also important that you preprocess it. This involves tasks like handling missing values, detecting outliers, making the data consistent, and more. By rigorously cleaning and preparing data, you lay a strong foundation for your AI agent's performance.
Step 4: Select your tech stack
There’s no one-size-fits-all tech stack, and yours will depend on your specific goals and the environment where your agent will be deployed.
Programming language
The programming language is the foundation of your AI agent’s code. In general, you want to choose your programming languages, such as Python and Java, based on the technology that you will use. To be more specific, you can employ the following technologies in your AI agent:
- Machine Learning. Learns from data to predict and uncover patterns.
- Natural Language Processing. Enables machines to understand and respond to human language.
- Computer Vision. Gives machines the power to see and understand the visual world.
- Robotic Process Automation. Automates repetitive tasks in digital systems.
Every AI agent is unique. Our experience in developing AI-based solutions, mobile apps, and other software products allows us to select the perfect tech stack for your project. And, we often blend several of them to ensure excellent performance in the AI agents we develop.
Scalability and maintenance
As your AI agent interacts with more people and collects more information, it will need to process and store this data efficiently. For small and medium businesses, we often recommend using cloud-based platforms. This way, our clients only pay for the storage space they need and can easily scale as their investment decisions change.
Additionally, as your AI agent evolves and new requirements emerge, you’ll need to be able to modify and improve its code. Our team always keeps up with market trends to anticipate any major needs in software. For every solution we develop, we provide post-deployment support to ensure that it remains adaptable and effective in the changing market.
Step 5: Design the AI agent
Work with your team to design the agent. In general, you need to decide about the agent’s build, how you will handle and process data, and consider user experience.
Agent architecture
Choosing the right architecture for your AI agent will define how easy it will be to maintain it in the future and how efficiently it can run. There are two general options that you can consider:
- Modular design. You’ll create multiple parts of your AI agent separately before assembling it into one working piece. This makes maintenance easier.
- Concurrent architecture. If you need the agent to run several tasks simultaneously, use a concurrent design.
If you are making an AI agent that handles conversations with the user, such as an AI chatbot, the architecture you choose might also affect your conversation flows.
To learn more about how to build a conversational AI bot, check our guide.
For instance, a modular design can offer greater flexibility when iterating on your decision trees or conversation flows, as it allows individual components to be modified without affecting the entire system. Meanwhile, a concurrent design might be better if your AI agent will handle multiple conversations simultaneously.
Data handling
Define how your agent will get data. For example, you can design a chat interface where a user can enter information for your agent to process. Similarly, determine how the agent will respond. For instance, you can set it to reply to a user or update a spreadsheet based on the processed data.
User experience
If you’re having your AI agent interact directly with users, design its appearance. Use buttons, colors, and text that reflect your brand. Don’t forget to add accessibility features, like text-to-speech and more.
We also recommend including a feedback mechanism in the AI agent. This way, users can freely provide feedback, which you can use to improve the system.
Step 6: Test the AI agent
Like any complex system, thorough testing is crucial for your AI agent’s success. Testing helps identify glitches, biases, or unexpected behavior in your agent. It also highlights areas where the agent’s interaction with users can be improved.
You can perform the following tests on your AI agent:
- Unit testing, which involves testing individual modules of the agent’s code to ensure they function correctly in isolation
- Integration testing to verify how different parts of the agent work together seamlessly
- Functional testing to check the overall functionality of the agent against its intended use cases
- Usability testing, which involves observing real users interacting with the agent and identifying any usability issues
Optionally, perform edge case testing to see the boundaries of your AI agent by feeding it unexpected or extreme inputs.
Step 7: Deploy and monitor your AI agent
The last step is integrating the AI agent with your existing systems and workflows. If it will handle sensitive data, make sure that you implement proper security measures to protect it and prevent unauthorized access.
To ensure your AI agent performs at its peak, monitor it regularly. Track key metrics like accuracy, response times, and resource usage to identify performance issues. Alternatively, actively gather user feedback to understand how people interact with the agent and identify areas for improvement.
What’s the Difference Between an AI Agent and an AI Chatbot?
AI chatbots and agents might have overlapping characteristics in some aspects, but they are different. Both can use Natural Language Processing to understand text and may rely on similar Large Language Models (LLMs) for their responses.
The key difference lies in their actions.
AI chatbots directly interact with the user either through text or voice. They can help you retrieve answers to questions and assist with some low-level tasks, but they cannot take independent actions.
On the other hand, AI agents can act autonomously. You can set them up with or without a user interface, since their goal is to complete the tasks you want them to perform.
