When ChatGPT arrived, it revolutionized how we interact with AI, making tasks like summarizing articles and planning trips a breeze. Thanks to OpenAI, you can now create personalized ChatGPT models, called GPTs, tailored to your specific needs. In this tutorial, we’ll walk you through the simple process of creating your own GPTs in just five easy steps. Let’s get started!

Custom ChatGPT


  • In five simple steps, this tutorial will guide you through creating personalized ChatGPT models, known as GPTs.
  • GPTs (Generative Pre-trained Transformers) are powerful language models that can be customized for tasks like text generation and summarization.
  • Custom GPTs offer personalized learning tools, creative content generation, specialized knowledge access, workflow optimization, and enhanced customer experiences.
  • To create a custom GPT, you need a ChatGPT Plus or Enterprise account and clear goals for your GPT’s tasks, persona, and data integrations.
  • Log in to, enter initial instructions, configure your GPT, upload knowledge files, and publish your custom model.

What are ChatGPT and GPTs?

GPT stands for Generative Pre-trained Transformer, a deep learning model used primarily in Natural Language Processing (NLP). OpenAI’s GPT models, including the latest GPT-4 Turbo, are transformer-based language models pre-trained on vast text corpora. They can be fine-tuned for text generation, summarization, and question-answering tasks.

ChatGPT, based on these GPT models, is a conversational AI designed to be helpful, harmless, and honest. It can handle a wide range of topics. OpenAI’s recent update allows users to create custom GPTs tailored to specific purposes.

Why Create GPTs?

Creating custom GPTs unlocks numerous possibilities:

  • Personalized Learning Tools: Tailor a GPT to serve as an academic assistant that adapts to your getting-to-know pace and style. Whether you’re reading a new language, getting to know a complex challenge, or preparing for exams, a custom GPT can provide personalized seed tutoring, quizzes, and study guides.
  • Creative Content Generation: Leverage GPTs to power your creativity. Whether you’re a creator, marketer, or content creator, a custom GPT can help you brainstorm thoughts, write articles, generate advertising and marketing copy, or even create poetry and stories, all tailor-made to your unique style and needs.
  • Specialized Knowledge Access: Develop GPTs that function as specialists in unique fields consisting of law, medicine, finance, or engineering. These specialized GPTs can provide designated facts, solve complicated questions, and help in professional selection-making, ensuring you get admission to high-quality, area-unique understanding at your fingertips.

    Develop GPTs that serve as law, medicine, finance, or engineering experts. These specialized GPTs can provide detailed information, answer complex questions, and assist in professional decision-making, ensuring access to high-quality, field-specific knowledge at your fingertips.
  • Streamlining Workflows: Optimize your workflows by creating GPTs for project management, data analysis, and reporting. Custom GPTs can track project progress, generate detailed reports, analyze data sets, and even automate routine tasks, freeing up time for more strategic activities.
  • Enhancing Customer Experiences: Implement GPTs to improve customer interactions and service. From personalized product recommendations to handling customer inquiries and providing detailed support, custom GPTs can enhance the customer experience by delivering accurate and prompt responses tailored to individual needs.

This tutorial will show you how to create custom GPTs without coding skills.

Preparing to Create Your Custom GPT


  • A ChatGPT Plus or Enterprise Account: Custom GPTs aren’t available to free-tier users.
  • No Coding Skills Required: The GPT builder interface is user-friendly and accessible, allowing you to customize your GPT with simple text prompts.

Setting Your Goals

Before starting, define your goals and intended use cases. Consider the following:

  • Tasks you want your GPT to automate: Do you need it to handle emails, provide data analysis, or create content?
  • The persona and tone of your GPT: Should it be professional, casual, or humorous?
  • Data sources or APIs for integration: Connect real-time data or specialized databases to enhance your GPT’s capabilities.

Clear goals will help shape your prompts and optimize your GPT for specific needs.

How to Create Your GPT: Here are 5 Easy Steps

Let’s dig in:

Step 1: Log in and Access GPT Builder

  • Go to and log in: Use your ChatGPT Plus or Enterprise account credentials.
  • Click on Explore in the sidebar: This will take you to the GPT creation menu.
Log In and Access GPT Builder
  • Select Create a GPT: This option will launch the GPT creation interface.
Select Create a GPT

Step 2: Enter Initial Instructions

  • Describe your GPT’s purpose: Provide a clear description in the GPT creation interface. For example, “Create a GPT to create a doodle of an image.”
  • Interact with the builder: Based on your instructions, the GPT builder will suggest a name, profile picture, and initial behavior. You can accept these suggestions or modify them as needed.

Save and Publish

  • Save your GPT: Once you are satisfied with your configuration, click Save (or Update if you are modifying an existing GPT).
  • Choose sharing options: Decide who can access your GPT—Only me, only people with a link, Public, or Anyone at [your company] for Enterprise users.
  • Confirm to finalize: Click Confirm to publish your GPT.
Share GPT

Step 5: Testing Your Custom GPT

  • Interact with your GPT: Test it by asking questions or giving tasks related to its intended purpose.
  • Evaluate accuracy: Ensure it generates correct and relevant responses based on the uploaded knowledge files.
  • Refine as needed: Adjust instructions or configuration settings to improve performance.
