How to Create an AI Agent? A Comprehensive Guide in 2025

Artificial Intelligence (AI) agents are an increasingly important element of current technology in 2025. According to a May 2025 survey by PwC, 79% of senior executives indicated that AI agents are being introduced into their organizations, and 66% of them were seeing actual value through productivity efficiencies from AI agents. 

These agents are not a vision of the future; they are the competitive differentiator for today’s industries. AI agents can service a range of use cases, from the simplest customer support processes to making complicated business decisions on behalf of an organization. With AI agents, automation, intelligent decision-making, and personalized user experience, organizations and businesses can operate in real-time. For most companies, for them to stay competitive, knowing how to create AI agents is a priority strategy.

So, what are AI agents? An AI agent is an intelligent system that observes, acts, and decides without human intervention. They differ from traditional software, which operates solely on predetermined instructions; AI agents learn, adapt, and subsequently improve even without explicit instruction.

At Dextralabs, our teams capitalize on bonding with startups and enterprises from many countries in the USA, UAE, and Singapore, while deploying AI agents that exceed experimentation. We are focused on business-ready automation and decision intelligence, while ensuring measurable impact, scalability, and long-term success.

What are AI Agents?

An AI agent is more than a chatbot or an automated program – it is an intelligent system that perceives its environment, decides, and acts autonomously within its scope to achieve purposeful goals. In its most fundamental form, an AI agent employs Large Language Models (LLMs) as its “brain” to leverage advanced reasoning and natural language interpretation, along with contextual decision-making. 

Before we go deeper into the components and enterprise applications of an AI agent, you need to understand what is an AI agent and how to build one. But an AI agent is more than the model. To function effectively in real-world business scenarios, it includes:

• Tools and APIs – to execute different tasks, whether it’s to obtain some data, send an email, or analyze a document.
• Memory – short-term (to track active conversations) and long-term (to remember user preferences and business policies).
• Knowledge sources – enterprise databases, regulations documents, or integrated knowledge graphs – provide agents with real-time data to keep agents relevant and accurate.

Key Traits of AI Agents: 

• Autonomy: AI agents do not rely on step-by-step programming to decide each action. As a result, agents are models of autonomy and essentially illustrate how to build an autonomous AI agent that automates a task, while directing its own evolution as it learns and adapts.
• Flexibility: AI agents can evolve and develop as they interact with new data or in a changing environment. This means they can work with more intricate workflows, which necessitate handling dynamically changing data.
• Continuous Learning: AI agents can constantly learn and improve accuracy, speed, and performance through feedback and retraining, correcting learning errors, and essentially improve along the way.

At Dextralabs, we have seen that organizations with teams that know how to build AI agents and do so with personalized, prompt engineering, domain-specific knowledge, and scalable deployment strategies yield the highest return on investment (ROI). That way, their agents do not remain prototypes; they move into business-ready systems. Furthermore, knowing how to create AI agents with a solid foundation increases flexibility and future-proof ability.

The Step-By-Step Process of Building AI Agents:

If you’re wondering how to build an AI agent step-by-step guide, the process involves structured planning, the right tools, and continuous refinement. Similarly, it is for those seeking to learn about how to build an AI agent from scratch with ChatGPT; what is needed is a methodology that incorporates scale and compliance. Let’s break it down. 

Step 1. Define the Objective and Scope of the Agent

Clarity is everything. Prior to building anything, establish what the agent will do, what objectives need to be met, and under what circumstances it will operate in. 

Examples: 

• A customer support agent responds to frequently asked questions.  
• A research assistant who summarises academic papers. 
• A compliance checker that checks for adherence to regulations. 

At Dextralabs, we help clients map their business goals to technical goals. So, AI agents are designed with a clear ROI in mind when they ask how to build AI agents effectively. 

Step 2. Select the Right Stack

The technology stack defines the extent of your agent’s performance and how it scales. 

• LLMs (Large Language Models): GPT, Claude, PaLM, LLaMA, Gemini DeepSeek V3. For developers looking for a way to open AI how to build an agent, GPT models are a strong base for reasoning, generality, and natural language understanding. 
• Frameworks: LangChain, LangGraph, AutoGen for orchestration.
• Development Platforms: Google Vertex AI, Microsoft Azure AI, AWS Bedrock. Google Vertex AI, Microsoft Azure AI, AWS Bedrock. Developers may explore how to build an AI agent in Python to customize logic and integrations.

Dextralabs considers stacks based on performance but also on scalability, compliance and whether it integrates into enterprise workflows.

Step 3. Collect and Prepare Training Data

Data is the backbone of any intelligent agent. In order to operate appropriately, agents rely on a curated set of data—whether it is text, code, customer conversations, or any other proprietary business documents. Data preparation, through cleaning, labeling, and preprocessing helps to limit bias and build accuracy. 

Even the best model can only take a product and service so far with bad quality data. The role of Dextralabs is to help organizations curate, refine, and secure proprietary datasets. This foundational opportunity is important for anyone wanting to explore how to build AI agents for applications in the real world.

Step 4. Choose Development Platform and Libraries

To decide between open-source software and licensing platforms has consequences with respect to costs and control.

• Open-source: A more flexible solution, though it may require more expertise.
• Proprietary/cloud-native: Faster to get going and ready for enterprise, though potentially more expensive. 

At Dextralabs, we care and want to help your business balance performance and costs when trying to figure out how to create AI agents that meet your needs.

Step 5. Test, evaluate and refine

AI agents are not built once—they are tested and refined multiple times. 

• Metrics to evaluate: accuracy, latency, compliance, and safety.
• Refinement process: gathering feedback, tweaking prompts, retraining models.

Dextralabs build a focus on real-world evaluations, examining how agents maintain performance beyond benchmark evaluation.

Step 6. Deployment and Integration

Your deployment choices can impact both future scaling and performance.

• Options: Cloud, On-premises, & Hybrid. 
• Integrate: to integrate with other CRMs, ERPs, or custom created business systems. 
• Oversight: continuous/seamless improvement & performance oversight.

At Dextralabs, we offer end-to-end deployment services for enterprises who are implementing AI agents for the first time and want to adapt as their business needs evolve.

Key Considerations for Building AI Agents

Building AI agents in 2025 entails much more than simply connecting to a Large Language Model (LLM). Even though LLMs provide the “brain,” a functional and business-ready agent requires several layers around them to provide context, flexibility, and reliability. 

Understanding how to build AI agents effectively means considering memory, adaptability, and integration with existing systems. Below are the top critical components every enterprise should consider when developing AI agents.

1. Memory

Memory plays a significant role for AI agents to progress beyond simply providing static, one-way responses. 

• Short-term memory is needed if the agent is going to have an active conversation, or be engaged in a realtime activity. For example, a customer support bot should be able to recall a customer’s question while that chat session is still open. 
• Long-term memory allows the AI agent to recall previous conversations, preferences, contexts and outcomes so it can continue on in a similar way to a human being in an interaction. Agents are able to offer human-like and personalized interactions across the different touchpoints.

Dextralabs designs memory architectures that balance privacy, ensuring enterprises can build AI agents to deliver personalization without compromising compliance. 

2. Tool Integration

Selecting the right APIs and automation tools is crucial for anyone looking to learn how to build an agent AI, as it ensures seamless execution of complex workflows.

Tools provide an agent with many options that go beyond text generation. These can range from:

• APIs (like a CRM or ERP integration) to fetch and update real-time data. 
• Calculators and Data Parsers for analytic functions.
• Task automation plugins that allow the agent to execute operational actions like scheduling a meeting for a user or completing a transaction. 

At Dextralabs, our AI Agent Development Services prioritize tool orchestrations that fit in naturally with the business workflows, so we reduce manual bottlenecks and increase ROI.

3. Knowledge Integration

LLMs are powerful, but they often lack expert knowledge or are not based on current data. That’s where knowledge integration comes in:

• Databases & Document Stores for proprietary business knowledge.
• Retrieval-Augmented Generation (RAG) Pipelines to retrieve the most relevant and accurate content at the time of the query.
• Continuous Knowledge Updates Agent that boots up with the necessary business rules and legislation.

Dextralabs team specialize in building knowledge pipelines that integrate proprietary data with external data sources to provide businesses with accurate and contextualized AI agents.

4. Prompt Engineering

Prompt engineering is a foundational element of every AI agent, as it provides a mechanism for how the model conceptualizes tasks. 

• Structured Prompts guide the agent’s behavior and ensure consistency.
• Dynamic prompt adjustments based on context, user intent, and the environment.
• Safety Prompts are a way to define prohibited or non-compliant responses. 

At Dextralabs, we employ our process of tailored prompt engineering and utilize industry standards as a guideline, while agents remain effective and safe within enterprise environments.
