What Are AI Agents?
If you have used ChatGPT, you already know language models. But an AI agent is more sophisticated: it is a system that can make decisions, execute actions and learn from results.
While a chatbot answers questions, an agent can:
- Research information across multiple sources
- Perform tasks in external applications
- Make decisions based on rules and context
- Iterate until an objective is complete
"AI agents represent the next major leap in business productivity." — Andrew Ng, Founder of deeplearning.ai
An Agent's Technical Architecture
A typical AI agent has four main components:
1. Language Model (LLM)
The agent's "brain". It processes instructions, generates responses and makes decisions. The most widely used include:
- GPT-4 (OpenAI)
- Claude 3 (Anthropic)
- Gemini Pro (Google)
2. Memory
Allows the agent to remember context between interactions:
- Short-term: Current conversation
- Long-term: History, preferences and lessons learned
3. Tools
Functions the agent can execute:
- Internet searches
- Database queries
- Sending emails
- API calls
4. Planner
The component that breaks complex objectives into executable steps.
Business Use Cases
Customer Support Agent
Input: "I want to return my order #12345"
The agent:
1. Checks the order status in the CRM
2. Checks the return policy
3. Generates a shipping label
4. Updates the ticket
5. Sends the customer a confirmation email
Market Research Agent
Input: "Research competitors in Ecuador's fintech sector"
The agent:
1. Searches public sources
2. Analyses social media
3. Extracts data from LinkedIn
4. Generates a comparative report
5. Identifies opportunities
Practical Implementation
Option 1: No-Code Platforms
For businesses that want to get started quickly:
- Relevance AI: Configurable agents without code
- Zapier Central: AI automations
- Microsoft Copilot Studio: For the Microsoft ecosystem
Option 2: Custom Development
For specific use cases:

Security Considerations
Agents have access to critical systems. The following are essential:
- Least privilege: Only the necessary permissions
- Comprehensive logging: Record every action
- Human validation: For high-impact actions
- Sandboxing: Isolated environments for testing
