How to Build AI Agents: An 8-Step
Development Guide

What is an AI Agent?

An AI agent is a software program powered by artificial intelligence, designed to work autonomously on your behalf. Imagine a scenario where routine, time-consuming tasks like form filling, appointment scheduling, and answering basic customer questions take up most of your team’s time.

This prevents your team from focusing on higher-value tasks like solving complex customer problems and driving innovation.

AI agents solve this problem by automating these repetitive tasks, freeing up your human resources to work on strategy and activities that require human skill.

Let’s look at some tasks that AI agents can perform for you.

Tasks AI Agents Can Perform:

The points we’ve covered above merely scratch the surface of what AI agents can do. You can train these intelligent agents to handle a vast array of tasks for your specific needs.

Now, let’s see how these AI agents work.

How Do AI Agents Work? Understanding the Basics

To better understand how agents work, let’s break it down to the basics. There are 7 main capabilities AI agents have:

1. See and Hear (Perception):
AI agents take in information from their surroundings, this could be text, audio, or visuals.

2. Processing Information (Cognition):
Involves analyzing information using machine learning to understand what this information means.

3. Making Choices (Decision-Making):
They use what they have learned to make decisions to get desired results.

4. Taking Action (Execution):
They implement or do a specific action based on the choice made.

5. Improvement (Learning):
As they handle more tasks, they learn from them (successes and mistakes) and improve.

6. Keeping Track (Memory):
AI agents store information from their interactions for use in the future.

7.Using Tools (Utility):
They connect to external tools and online resources to enhance their capabilities.

Discover The Types of AI Agents with Examples

We can categorize AI agents into two; based on how they think (reasoning), and based on their applications in the real world.

Types of AI Agents Based on Reasoning Power

1. Simple Reflex Agents: Quick Reactions, No Memory

These are the most basic kinds of AI agents. They respond directly to inputs, based on predefined rules.

• Spam Filter Agents:
  Analyses email categories like sender, content, and links to identify and isolate unwanted emails.
• Work Task Categorization Agents:
  Identifies emails that require actions to be taken by analyzing sender, subject, and content for project-related keywords and urgency indicators.

2. Model-Based Reflex Agents: They Can Remember Past Interactions

Model-based reflex agents remember their environment. They use this “mental picture” or "Model" to make decisions, instead of just reacting to a given input at the time.

• Inventory Level Prediction:
  The agent analyzes sales data and supply chain information to predict future inventory needs and automatically triggers restocking orders.
• Automated Form Completion:
  The agent used previously entered data to predict and auto-fill related form fields.

How to Create Your Own AI Agent: A Simple Step-by-Step Guide (8 Steps)

It’s true that AI agents are highly advanced programs, but you can create your own agent using these simple steps.

Step 1: Pinpoint Your Problem (What do you need it for?)

The first step is to decide what job you want your AI agent to do. The objective here is not to just “make things better,” but to define the exact goals. Do you want it to automate emails? Track your inventory? Or Something else? Be very clear about your goals.

Step 2: Choose How You Will Build (Who Can Create It?)

There are 4 ways you can approach this, depending on your specific situation.

Build AI agent with low-code/no-code tools:
If you only have simple tasks to do, you can build AI agents with no-code and low-code tools.

Hire Freelance AI Developers:
If your AI agent is for your business, and needs to consistently perform well, hiring freelancers could be a cost-effective option.

AI Development Companies:
If your goal is custom AI agent development for more complex tasks, and if you have a decent budget, hiring a dedicated AI development service provider would be faster and cost-efficient in the long run.

Consider your specific needs and budget. Experiment with no-code/low-code tools if you’re just exploring AI agents.

For small businesses with budget constraints, freelancers can provide valuable assistance. For established businesses on a mission to improve efficiency, an AI development company is often the most strategic choice.

Step 3: Gather Your Data (What Information Will It Use?)

For your AI agents to work properly, you have to train them with your own data. Identify where your data will come from. Examples could be your customer feedback forms, reports from your engineering teams, and any data relevant to your goal.

Guide for Preprocessing Data:

1. Clean and prepare your data:
Remove inconsistencies, errors, and unwanted information.

2. Remove irrelevant information:
Focus on data directly related to your AI agent’s tasks.

3. Keep a fixed standard for all your data:
Ensure that your structure and format are consistent.

4. See if any data is missing or incomplete:
Add missing data to refine it and remove what’s not needed.

5. Categorize the data with suitable labels:
Organize your data so that your AI agent can learn in the most efficient way.

For instance, if you have an ecommerce business, you probably have a lot of customer reviews or support tickets. This can be used to train a customer service AI agent.

Step 4: Choose Your Tools (What software will you use?)

The tools you should use to build your AI agent will depend on what your goal is. Consider factors like user-friendliness, how it connects with other software and tools, and how much they will cost. An important choice you will make in this step is the AI model you will use.

Lastly, also consider how your AI agent will work with your current systems. It will have to use APIs to easily communicate and perform tasks inside your software ecosystem.

Step 5: Train Your AI Agent (Teach it how to think)

Although you’ve already chosen a machine learning model like BERT or GPT-4, these are pre-trained models. This means that they will know about broad concepts, but you need to “teach” them how your business and processes work.

1. Use the data you have already prepared in the previous steps to train the model (using frameworks like TensorFlow or PyTorch).

2. Define your training parameters. This is you telling the AI model how much you want it to learn from the training data, how many times it should process the data, and so on.

3. Make constant tweaks to your parameters to improve the performance of your AI agent.

Step 6: Test and Improve (Make sure your AI agents work well for all tasks)

• Introduce new data that the AI model hasn’t seen before (testing dataset) to see how it performs in real-world scenarios.
• Take this a step further and introduce it to unexpected data like unusual customer requests or unclear instructions to see how it handles these situations.

Measure how accurate your AI agent is using a scoring mechanism for specific factors.

• Precision:
  Check the AI agent's outputs for correct responses, and see how often it gets it right.
• Recall:
  How often does the AI agent produce the right answers?
• F1-score:
  This is a combined score that combines Precision and Recall to see the overall performance.

These scores help you understand how reliable and useful your AI agent is.

Step 7: Deploy and Monitor (Implement and see how it performs)

1. Choice a deployment method to host your AI agent (cloud platforms, physical servers)

2. Connect your AI agent with your existing software systems and workflows using APIs.

3. A “phased rollout” is the best option where you implement your AI agent in some areas of your business, see how it performs, and improve it with new appropriate changes before fully launching it. 

4. Use monitoring tools to check your AI agent’s performance in real time. 

5. Always be sure to keep different versions of your AI agent with you to roll it back to a previous version, in case an update you make breaks the performance. 

For Example:
If you are building an AI agent for your internal teams, it may be difficult for everyone to adapt. Try giving the AI agent to one team, and then slowly expand to other teams. The feedback you collect will help you improve your AI agent, and the team where you implemented the agent can help others adopt it.

Step 8: User Training and Documentation (To ensure smooth adoption)

1. Develop User Guides: Create clear documentation for users explaining how to use your AI agent.

2. User Training Sessions: Conduct training sessions for your employees to ensure that your AI agent is effective.

3. Create Troubleshooting Guides: Write guides to show how users can solve problems and address common issues (FAQ).
