The first step of building an intelligent agent is simple. What exactly is it going to do? Begin by outlining the purpose of developing an AI agent. There could be numerous real-world applications for using AI agents. However, the basic requirement is to identify the purpose of building it.

Pro Tip 💡 - We always recommend starting with a single and well-defined use case. It's tempting to build a "do-everything" agent. But focused agents deliver better ROI and faster time-to-value.

Training Data Collection

Before moving to building agents, you must assess the technical landscape. The ability of an AI agent to process user inputs and generate human-like responses depends heavily on the quality and diversity of the data it learns from. This process involves gathering large datasets that include historical data, real-time user interactions, relevant information, user queries, and feedback.

So, to build an effective AI agent, start by gathering relevant data from diverse data sources. Collect datasets from various sources like databases, APIs, user interactions, local files, cloud storage, or enterprise systems to ensure comprehensive coverage. For instance, if you’re creating a chatbot, gather past chat logs and customer queries.

Here is how we do it the right way:

1. Identify Data Sources

2. Gather Quantitative Data

3. Collect Qualitative Insights

4. Ensure Data Accuracy

After collecting the data, preparing high-quality training data is essential for effective AI agent development. We use visualization tools to identify any issues in the raw data.

Planning AI Agent Tech Architecture

When creating agents, one of the crucial things to be taken care of is planning the tech architecture aptly. From identifying the right approach to the technology stack and even the platform, everything impacts the success of the agents. So, when building the agents, our AI developers take utmost care of the following.

Choosing the Right Approach

With the purpose in mind, decide on the brain of the agent. You can choose from a few approaches:

Large Language Model - A pre-trained large language model for advanced language understanding or general intelligence. For a conversational agent, models like GPT-4 or Claude could be a great starting point.

Retrieval-Augmented Generation (RAG)  - If your agent frequently requires access to external information, such as documents or knowledge base content, we utilize a Retrieval Augmented Generation approach.

Custom ML model - If you have proprietary data and a specific prediction or classification task, a custom ML model may be necessary. We recommend that generic models may not be suitable for your needs.

Our Tip 💡- Leveraging our top AI development expertise, we can help you identify the best approach and even help you build a custom model for your unique and specific use case.

Designing an AI Agent

When designing the AI agents, it is crucial to understand the type of design feasible to address business requirements.

1. Modular design: Create individual modules of the AI agent separately and then put them together in the agentic AI systems. This method makes it easier to update, fix, and grow the system because changes to one module do not impact others.

2. Concurrent design: Build a system where multiple tasks run at the same time. This approach is best for agents who need to manage real-time operations or handle several customer conversations at once.

Backend Technologies

The backend of an AI agent is essential for its functionality and scalability.

Python is the preferred language for AI and machine learning, featuring libraries like TensorFlow, PyTorch, and Scikit-learn for developing AI functionalities.

JavaScript/Node.js is ideal for integrating AI models with web applications or chatbots, handling asynchronous operations effectively.

Java is suitable for enterprise-level applications that need robust & high-performance systems. Therefore, by understanding your business goals, we choose the programming language that can complement the entire development process.

Selecting the Right Platform

There are numerous AI agent frameworks to choose from. If you are also searching for the one that could fit your ideation, our curated list could be a great place to start. While we will not focus on every framework here, we can take a quick glance at the top ones-

For projects that use deep learning, TensorFlow and PyTorch are popular frameworks.

For simpler algorithms, you can use scikit-learn.

If your project involves natural language, frameworks like Hugging Face Transformers or LangChain agents are good choices.

After selecting your tools, set up your development environment. Install the necessary libraries and test the setup with a simple program to ensure everything works properly.

Develop the AI Agents

The next step in how to build an AI agent is to develop custom AI agents tailored to specific business requirements. Here, the apt execution of your ideation takes place. At this stage, we focus on designing and refining the core AI model of the agents, ensuring it meets the intended objectives. However, there are different approaches to developing the AI agent.

Like developing autonomous agents using LangGraph, building intelligent Agents using OpenAI, or creating Artificial Intelligence agents with Python or LangChain agents. To help you understand better, we will use a simple rule-based agent to illustrate the process:

1. Install Python and Necessary Libraries

Use libraries such as nltk for text processing.

2. Define Rules

Create a set of conditions for recognizing greetings and generating responses: python

3. Process User Input

Convert user input to lowercase and check for greeting words: python

4. Expand Functionality

Improve your chatbot by adding more rules or integrating simple ML models to handle a wide range of queries.

Selecting the right tool is essential to support the development and optimization of the AI agent. We also verify compliance with data protection regulations and industry standards like GDPR and CCPA.

Train the AI agents

Now is the time for your AI agents to prepare for performing the tasks. If the selection is to choose a pretrained LLM, there would be a need to fine-tune the LLM to deliver the desired outcome.

If the selection is training an intelligent agent from scratch, you will need labeled data. Use the supervised learning method that includes historical records and knowledge pairs, and then feed this data to machine learning algorithms. To ensure the model generalizes well to unseen data and avoids overfitting, we also apply cross-validation during the model training process.

The outcome of this step is to create a brain for the AI agents that is ready. So it could be either a trained model file or a thoroughly configured external model.

Integrate with User Interfaces and Enterprise Systems

An intelligent agent is useless if it can not interact with your business environment. This step involves integrating the agent with the user-facing platforms where it will operate and ensuring access to a comprehensive knowledge base. Key integration points include:

• The user interface, such as a chatbot interface on your website

• An internal application for your employees

• A seamless connection to your CRM, ERP, or other enterprise systems

When integrating the AI agent, ensure compatibility with your existing technology stack to maximize flexibility and ease of deployment.

The goal of this step is to make the agent a natural and accessible part of your existing workflow.

Testing & Optimization

Before deploying the artificial intelligence agent, test it thoroughly to find any errors or performance issues.

So you are already done with the process of “how to create an AI agent?” But here comes a crucial step! 

Once the agent is created, it should be thoroughly tested. The testing process often creates new data stores or resources to support validation and optimization. Test and iterate. Use feedback to improve it.

Simulated Incident Testing: Test the AI agents by giving them simulated incidents to see how well they identify, classify, and resolve them.

Human-in-the-Loop Testing: Upon deploying the AI agents, let human technicians review and intervene when the AI requires assistance with incidents.

Continuous Learning:  As new data comes in and more incidents get resolved, make sure the AI can learn from each case to improve over time.

Deploy & Monitor Agent Performance

With testing complete and your agent optimized, it’s time for deployment. The AI agent is now live and working in a real-world setting. At this stage of the development process, it is essential to select the deployment options. Decide whether to host your agent on-premise or in the cloud.

However, the work doesn’t stop here. Continuous monitoring is crucial to ensure long-term success. Use analytics tools and monitoring systems to track key metrics such as:
