Create Your Own AI: A Step-by-Step Guide to Setting Up a Custom GPT

Artificial intelligence is no longer something you have to use as-is. By following the steps in this guide, you can create and customize your own Custom GPT to meet your specific needs.
AI is no longer just a technology we see in movies; it’s at the center of our lives. Thanks to OpenAI’s Custom GPT feature, anyone can now create a personalized AI model tailored to their specific needs and interests.
In this guide, we’ll walk you through how to create a personal AI assistant. Whether you want a daily task organizer, a guide to help you learn a new hobby, or just a friend to chat with, we’ll show you how to build a personal AI step-by-step.
What is a Custom GPT? What is it used for?

In its simplest definition, a Custom GPT is a version of ChatGPT customized for a specific purpose. Unlike the general-purpose ChatGPT, Custom GPTs are equipped with specific instructions, information, and capabilities that you define. This results in an AI model that is an expert on topics you choose and responds in the manner you prefer.
How to Create a Custom GPT: A Step-by-Step Guide

Creating your own personal AI assistant is easier than you think. Follow these steps to bring your first Custom GPT to life in minutes.
Important Note: To use this feature, you must have a ChatGPT Plus or higher subscription.
- Step #1: Log in to ChatGPT and Go to the “GPTs” Section First, go to chat.openai.com and log in to your account. Click on the “GPTs” tab in the menu on the left.
- Step #2: Click “Create” On the page that opens, you’ll see a “Create” button in the top right corner. Click this button to go to the customization screen.
- Step #3: Start Chatting with the GPT Builder You will be presented with two main sections: “Create” and “Configure.” The “Create” section is where you build your GPT by chatting with it and describing what you want.
For example, you can say: “I want to create a chef assistant that provides healthy and practical recipes. Let’s call it ‘Flavor Wizard’.” ChatGPT will automatically generate the GPT’s profile picture, name, and basic instructions based on your request.
Step #4: Refine and Train Your GPT While training a GPT through conversation is easy, switching to the “Configure” tab to adjust the details will give you more consistent results.
- Name: You can change your GPT’s name here.
- Description: Add a brief description of what your GPT does.
- Instructions: This is the most critical part! You must write detailed instructions here about how your GPT should behave, what information it should focus on, and what tone it should use (e.g., friendly, professional, humorous). The more detailed your instructions, the better the results.
- Conversation Starters: Add sample questions to make it easier for users to start a conversation with your GPT (e.g., “Give me a chicken recipe I can make in 30 minutes.”).
- Knowledge: You can upload specific files (PDF, TXT, etc.) that you want your GPT to know. For example, you can add a document with your own recipes or lecture notes.
- Capabilities: Here, you can select whether your GPT can browse the internet (Web Browse), create images with DALL-E (DALL-E Image Generation), or perform code analysis (Code Interpreter).
Step #5: Test and Save After making all your settings, you can test your GPT in the “Preview” section on the right side of the screen. Ask it questions and check if its answers meet your expectations. If you’re happy with everything, you can save your GPT. After saving, you’ll see three options:
- Only Me: Only you can see and use the GPT.
- Anyone with the Link: People you share the link with can use your GPT.
- Public: Your GPT can be used by anyone.
