Building Your Custom GPT: A Comprehensive Guide to OpenAI's New Tool

Written on

Chapter 1: Introduction to Custom GPTs

Most people have probably encountered ChatGPT by now. For those who haven't, it's a generative AI that produces human-like text, images, and videos. While ChatGPT itself is impressive, OpenAI has recently rolled out a feature allowing users to create custom GPTs. This means you can develop your own Generative Pre-trained Transformer, using pre-existing knowledge and specific parameters. This development is groundbreaking, reminiscent of Apple's introduction of the App Store in 2008, as OpenAI now offers a marketplace for personalized AI solutions, revolutionizing our interactions with technology.

Building Your First GPT

Let's embark on the journey of creating your very first GPT. Constructing a personalized GPT model provides a hands-on method for developing your own AI and language processing capabilities. It allows you to delve into the complexities of model architecture, training, and optimization, all while customizing the model to meet your unique needs. I’ll demonstrate creating a GPT that complements this article, enabling you to explore topics beyond what I’m presenting today.

Creating a basic GPT is straightforward since it revolves around dialogues. You can easily articulate your intention. For instance, I will initiate with: "Create a chatbot that guides users in developing their first GPT independently."

This simple prompt triggers the GPT creation process, and you’ll soon receive a response. The editor is divided into two panels: the left side is for editing, while the right side displays a preview of your GPT.

GPT Editor Interface

The next steps involve following the commands and inquiries posed by the GPT builder. This will help generate a name for the skill, provide an icon, and establish additional context.

GPT Skill Creation Steps

In the concluding phase of your interaction with the GPT builder, you will be prompted to define the purpose, scope, and any specific information that the AI lacks. Throughout this process, it’s essential to continually test the output on the right side to ensure that the scope and data are accurate.

Testing GPT Output

Fine-Tuning Your GPT

After providing comprehensive information, navigate to the “Configure” tab. Here’s where the real magic happens, and much of the information will already be filled in by the GPT builder.

Fine-Tuning Your GPT

In this section, you can finalize and refine the information, ensuring the automatically generated instructions are accurate. Review the conversation starters, adding or removing as needed. Additionally, define the capabilities of your GPT, such as whether it should have internet access, generate images, or produce software and code.

Providing Custom Knowledge

At this stage, your GPT may still lack uniqueness. While it can deliver precise information based on your guidelines, it won't offer any new or proprietary knowledge unless you upload custom data. You can submit information in various formats, including:

  • Text files (.txt)
  • PDF files
  • Word Documents
  • CSV/Excel Spreadsheets
  • JSON or HTML files

The more diverse and extensive the information you provide, the more effective and powerful your GPT will become.

The Most Powerful Feature: Actions

Actions are specific responses tailored to user inquiries. For example, if someone asks about your data storage practices, an action could link to your website's privacy policy. If your GPT is designed to promote a shop, inquiries about opening hours should return a predefined response. Most actions are created using JSON or YAML formats and can connect to APIs for real-time information.

Releasing Your GPT

Finally, to launch your GPT, click “Save” at the top right, choose the desired level of public access, and you’re all set.
