AI just got personal. Whether you’re looking to generate professional-level logo designs or predict upcoming stock market prices, it’s now easier than ever to create a custom Generative Pre-trained Transformer, or GPT, to meet your specific needs. Using a paid ChatGPT plan, anyone can configure their own chatbot with a simple prompt and the click of a button.

But what’s the difference between a custom GPT and the original ChatGPT? How does it work, and what can it do for you? Learn the answers to these questions and more on Aquent Gymnasium’s latest livestream — or read on for a summary of the discussion.

Custom GPTs vs. ChatGPT

It’s all in the name! In essence, custom GPTs are exactly what they sound like: specialized versions of ChatGPT. ChatGPT is trained on a wide variety of subjects, but even with individualized instructions, it still operates within its trained parameters and guidelines. With a custom GPT, you can ensure laser focus on specific datasets and knowledge bases and adherence to unique tones and perspectives.

Let’s say you want to create a virtual tech support advisor that’s programmed to provide expert-level tech support, or maybe something more fun, like a GPT that takes personal details and interests and turns them into one-of-a-kind heartwarming holiday cards. By tailoring the custom GPT to your specifications, anything is possible.

Custom GPTs are also ideal for organizations that require AI integration with consumer-facing applications. Not only can you provide them with proprietary information and defined guardrails for its use, but you can ensure that it utilizes a specific brand voice when interacting with customers.

How the magic happens

Taking the first step towards creating your own GPT is as simple as creating a ChatGPT account and entering a prompt in the GT Builder’s “Create” mode. You can enter as many or as few details as you’d like — even the most bare-bones request will produce a response, but as with all AI systems, clear and specific instructions always generate the best results. No matter how involved your prompt is, the system will get the answers it needs from you by asking refining questions about your intended audience, preferences regarding the bot’s tone, and topics the bot should specialize in.

As you engage with and provide more information to ChatGPT, you’ll notice the fields in the Builder’s “Configure” mode will begin to auto populate and change based on your input. You can watch your initial prompt transform based on your conversation with the bot and make further modifications based on the results you’re seeing. There’s also an option to connect it to a third-party API or enable extra capabilities like web browsing, access to the DALL-E text-to-image model, and code interpretation. Perhaps most importantly, the custom GPT builder allows you to upload files containing specific data or knowledge you need your bot to understand and reference. Be sure to save your original prompt for reference before you get started, since it won’t be recoverable through ChatGPT once you begin fine-tuning it.

Once your chatbot has been customized to your liking, you can publish and share it with an audience of your choice or debut it in the public GPT Store. If any issues arise, you can always go back and edit the bot after it’s been published.

The power of a custom GPT

Now that you’re equipped with the knowledge you need to make your own personal GPT, you might be wondering — what else is in it for me? You already know that custom GPTs have the advantageous ability to be more specific and personalized than ChatGPT, but they also have the potential for scalability and adaptability and enhanced content creation.

Your GPT evolves with you, adapting to your needs as you grow. It’s your virtual sidekick, ready to tackle whatever challenges come your way. Need to quickly handle an influx of customer inquiries? Want content for a newly-launched blog page? By heading back to the GPT Builder and modifying your prompt, you can ensure that it evolves at a seamless pace.

Speaking of content creation, custom GPTs can be trained with niche datasets to produce high-quality specialized articles and social media posts. By providing data relevant to your particular industry or topic of choice, you can save time and resources by creating what is essentially an AI assistant that produces this content in a voice and style consistent with your brand.
