Start Building Your Own Custom GPTs (Detailed Steps and Video Included)

OpenAI just launched this cool new thing called GPTs, which lets you make your own custom ChatGPT. It's super easy, and you don't need to know coding or anything. You can use it for learning stuff, work, or just everyday tasks, like figuring out board game rules, teaching your kids math, or designing stickers.

Here's how it works: you just pop onto their website, start a chat, and set up some instructions and what you want it to do, like web searches or data analysis. And boom, you've got your own GPT, whether it's just for you, your company, or everyone.

They've also got this GPT Store where you can share what you've made and even earn some money if it gets popular. The store will show off the most useful and fun GPTs.

Plus, OpenAI makes sure your chats stay private and you get to decide if it shares data with any third-party APIs.

1) Access the Creation Interface
  1. Visit

  2. Start a conversation interface, the starting point for creating your own GPT.

  1. Provide Instructions and Additional Knowledge

  • Specify the tasks or functions you want the GPT to perform during the conversation.

  • Provide additional knowledge or information to help the GPT better understand and execute specific tasks.

2) Provide Instructions and Additional Knowledge
  1. Specify the tasks or functions you want the GPT to perform during the conversation.

  2. Provide additional knowledge or information to help the GPT better understand and execute specific tasks.

3) Choose Functions
  1. Decide what you want your GPT to do. This might include web searches, image creation, data analysis, etc.

  2. Select and customize these features as needed.

4) Share and Use Your GPT
  1. Once created, you can choose to use it for yourself, share it with your company's internal staff, or with the public.

  2. This allows your GPT to be used by a specific group or a wider user base according to your preferences.

5) Participate in the GPT Store
  1. A GPT Store is expected to be launched, where users can share their creations.

  2. In the store, GPTs can be searched and may rise in the rankings. The more they are used, the more income you may earn.

6) Consider Privacy and Security
  1. User privacy is protected, and conversations with GPTs are not shared with creators.

  2. If using third-party APIs, it is up to the user to decide whether to share data.

7) Connect GPTs to Real Applications
  1. Developers can define custom actions to enable GPTs to interact with external data or the real world.

  2. For example, GPTs can be connected to databases, email systems, or e-commerce platforms.

8) Exclusive GPTs for Enterprise Customers
  1. Enterprise users can create and deploy internal-only GPTs based on specific business needs.

  2. This includes customizing GPTs to meet the needs of specific departments, uses, or datasets.

How to Customize GPT Functionality?

In addition to the official web search, image creation, and data analysis, you can also use an API schema to customize the functionality of GPT. Consider the following:

Understanding API Schema
  • An API schema defines how to interact with external services, such as databases or web services.

  • It includes specific details of the interface, such as endpoints, request methods (GET, POST, etc.), parameters, and data formats returned.

Designing Custom Actions
  • Determine the specific actions you want the GPT to perform, such as reading data, sending messages, processing requests, etc.

  • Create a clear description and process for these actions, guiding how to design the API schema.

Building the API Schema
  • Design the API schema based on the needs of your custom actions, involving the necessary request parameters and expected response formats.

  • Ensure the API schema can effectively process requests and return the required data.

Integrating GPT and API
  • Use the API schema to integrate the GPT with external APIs.

  • Ensure the GPT can correctly interpret the results of API requests and respond based on this information.

Testing and Debugging
  • Test the custom functionality of the GPT in a real environment to ensure it operates correctly.

  • Pay attention to error handling, data accuracy, and response times.

Optimizing and Updating
  • Optimize and update the API schema based on test results and user feedback.

  • Continuously improve to ensure the functionality meets user needs.

Customizing GPT functionality using an API schema can make GPTs more powerful and flexible, allowing interaction with various external services and data sources, thus expanding their range of applications.

OpenAI is rolling out custom versions of ChatGPT for specific purposes, called GPTs. This new method allows anyone to create a tailored version of ChatGPT to better assist them in daily life, for specific tasks, work, or at home, and share those creations with others. For instance, GPTs can help learn the rules of any board game, teach kids math, or design stickers.

Anyone can easily build their own GPT without needing coding knowledge. You can make them for personal use, internal company use, or for everyone.

Creating a GPT is as simple as starting a conversation, providing instructions and extra knowledge, and choosing what it can do, such as web searches, image creation, or data analysis. Try it out at

Currently, example GPTs are available for ChatGPT Plus and Enterprise users, including Canva and Zapier AI Actions. OpenAI plans to offer GPTs to more users soon.

Since the launch of ChatGPT, people have been seeking ways to customize it to suit their specific uses. OpenAI introduced Custom Instructions in July, allowing you to set some preferences, but the demand for more control continued to grow.

Many power users maintain a list of carefully crafted prompts and instruction sets, manually copying them into ChatGPT. GPTs now do all that for you.

OpenAI believes the most incredible GPTs will come from community builders. Whether you're an educator, coach, or just someone who loves to build helpful tools, you don't need coding knowledge to create and share your expertise.

The GPT Store is expected to launch later this month. Starting today, you can create GPTs and share them publicly. Once in the store, GPTs become searchable and may climb the leaderboards.

We will also spotlight the most useful and delightful GPTs we come across in categories like productivity, education, and "just for fun". In the coming months, you'll also be able to earn money based on how many people use your GPT.
