How to Build Your Own AI Agent with Python (2025 Guide)

AI agents are transforming how we automate tasks. Here is how to build your own using Python.

What is an AI Agent?

An AI agent is a program that can perceive its environment, make decisions, and take actions to achieve goals. Unlike simple scripts, agents can adapt and learn.

Building a Simple AI Agent

import openai
from typing import List, Dict

class AIAgent:
    def __init__(self, name: str, system_prompt: str):
        self.name = name
        self.system_prompt = system_prompt
        self.memory: List[Dict] = []

    def think(self, task: str) -> str:
        self.memory.append({"role": "user", "content": task})
        messages = [
            {"role": "system", "content": self.system_prompt},
            *self.memory[-10:]
        ]
        response = openai.ChatCompletion.create(
            model="gpt-4",
            messages=messages
        )
        reply = response.choices[0].message.content
        self.memory.append({"role": "assistant", "content": reply})
        return reply

    def execute(self, task: str) -> str:
        plan = self.think(f"Plan steps for: {task}")
        result = self.think(f"Execute the plan: {plan}")
        return result

agent = AIAgent(
    name="Assistant",
    system_prompt="You are a helpful AI assistant that automates tasks."
)
print(agent.execute("Organize my Downloads folder"))
