How to build Custom GPTs

Making your custom GPTs is just one of the ways to leverage your content strategy and use ChatGPT with headless CMS. The good news is that you don’t need developer skills or any coding experience, all you need is to accept the help of GPT Builder.

In this tutorial you will learn how to build your custom GPTs, I will document the step-by-step building process. I am making a custom GPT that will become a BMCS expert who is ready to answer technical queries about open-source headless BCMS but also explain the concept of headless CMS for non-technical people.

Before I start with building let me introduce you to the concept of custom GPTs.

What are custom GPTs?

Custom GPTs, (short for Custom Generative Pre-trained Transformers), are personalized versions of the ChatGPT model that require no coding, so users can make their chatbot fit their unique needs.

This customization is achieved by inputting text prompts and instructions into the GPT builder and compiling these directives to create a tailored chatbot version. Additionally, users can provide additional context through file uploads and integrate the GPT with third-party services for expanded functionality. Custom GPTs can be shared among ChatGPT users or made public, enabling broader access and usage.

Benefits of creating custom GPTs

Creating custom GPTs offers several benefits:

  • Tailored responses: Custom GPTs allow users to personalize the responses of the chatbot to better suit their specific needs and preferences. This ensures that interactions with the bot are more relevant and meaningful.

  • Automation: To save time and effort, custom GPTs can automate repetitive actions like offering personalized suggestions or responding to frequently asked queries. Whether you are managing a small business or are a solopreneur, a personalized GPT will help you find the answers to all the questions you are sick of hearing.

  • Versatility: From customer support to content generation, custom GPTs are highly versatile due to their ability to be trained to perform many different tasks. Their versatility makes them an excellent choice for handling a wide range of commercial needs.
