How to Create a Custom GPT using GPT Builder? [Even Without ChatGPT Plus]

Table of contents

In 2023, OpenAI has spearheaded the development of Generative AI, with ChatGPT being one of its leading use cases. This development has also given rise to large language models such as GPT-3 and GPT-4. ChatGPT has seen vast use cases from answering simple questions like "Tell me a joke" to complex business applications like code generation and even creating an app. Microsoft has even integrated these language models into its Bing Search Engine.

Despite the enormous advancements in AI, we are only scratching the surface of its potential. With the recent launch of GPTs, it is evident that we can create custom Generative Pre-trained Transformers to suit various needs, such as training chatbots to mimic human responses or developing business chatbots.

While creating a chatbot by yourself mind sounds intimidating, creating a ChatGPT chatbot is not a complicated task. This blog will guide you to:

  • Create your own custom GPT without any coding skills
  • Demonstrate how you can create a chatbot without subscribing to ChatGPT Plus!

So, let's dive in!

Introduction to custom GPTs

Before we dive into creating your own custom GPT, let's take a moment to understand what GPTs are and how they can revolutionize your AI chatbot experience.

What are GPTs?

GPT, which stands for Generative Pre-trained Transformer, is a powerful language model developed by OpenAI. It can generate human-like text responses based on the input it receives. With the release of OpenAI's GPT Builder, users can now create customized GPTs tailored to their specific needs and goals.

Since the release of GPTs, users have created several custom ChatGPTs for different purposes. ChatGPT constantly creates several fun GPT versions that the company shares on its Twitter account for others to explore. They once shared a laundry GPT, and recently, in the spirit of the holiday season, they created a SantaGPT!

Benefits of creating custom GPTs

Building a custom GPT offers a range of benefits and opportunities. Here are a few reasons why you should consider creating your custom GPT:

Personalization: By creating a custom GPT, you can tailor the chatbot's responses and behavior to align with your specific requirements and target audience. This allows you to create custom ChatGPTs that understand your use case well. As a result, if this is a business chatbot, it can answer customer queries related to a subject easily and more accurately.

Automation: Custom GPTs can automate repetitive tasks, such as answering frequently asked questions or providing personalized recommendations, saving time and effort. Whether you are a solopreneur or running an SMB, a custom GPT will assist you in answering all the questions you are tired of answering.

Enhanced user experience: A well-designed custom GPT can provide a seamless and engaging user experience, offering accurate and relevant information to users in real time.

Versatility: Custom GPTs can be trained to handle various tasks and domains, from customer support to content creation. This makes them adaptable to various business needs.

  1. As you click on Create GPT, the GPT builder will appear with a split screen:

2. Now, put your instructions in the designated box and hit the Enter button

3. Then, based on your prompts, the GPT builder will offer you suggestions like Profile picture, Name of the chatbot, and default conversation starter question. You can either accept the suggestions, or you can ask the GPT builder to further modify the bot.

4. Now, you need to enter further prompts with specific instructions to fine-tune your GPT bot behavior. It's okay if you are unable to figure out what modifications you exactly need to do. Try with different relevant instructions and check the responses from the preview panel.
For example, if you are getting responses that are written in a more formal tone, you can simply ask the GPT builder to use a different tone or voice for that matter.

5. Keep refining your prompts until you get the responses you are looking for from your chatbot.

4. Configure the GPT

Now that you are done with the basic setup, it's time to customize it further.

  1. Click on Configure from the left pane of the bot builder window.
  2. Here, you can change your chatbot's name, the display picture, and the description.
  • Profile picture: Select the profile picture. Now you have two options. Either you can upload your own photo or generate a new one with the DALLE 3. If you want to add further instructions on how the image should be, click on the Create button and put your instructions.
  • Name and description: Give your custom GPT a name that reflects its purpose and write a brief description to provide user context.
  • Instructions: Enter instructions that guide your GPT's behavior and responses. You can either update the instructions that the GPT builder has generated, or you can add additional instructions to define specific actions, even provide guidelines for generating text.
  • Conversation Starters: Under this section, you can customize the initial prompts users will see when engaging with your chatbot. Click on the X button to remove any existing Conversation starters. Also, you can put a new prompt on the empty Conversation starters box.
    N.B: Try to craft conversation starters that align with your desired user experience and encourage meaningful interactions.
    For example, if you want to create a chatbot for your website featuring products, then the starter questions could be, “What is the price of ABC product,” “Tell me more about XYZ products.” These are leading questions that nudge users to understand your products better while prompting them to learn more.
  • Knowledge: If you want your chatbot to access specific knowledge sources or data, you can upload relevant files for your GPT to reference.
    Click on the Upload files button and add any relevant files to use as references.
    This can include industry reports, product manuals, or any other information that can help your chatbot provide accurate and up-to-date responses.
  • Capabilities: By default, the chatbot will have the ability to do Web Browsing and DALL-E Image Generation. Further, if you want the bot to run any code or analyze data, Check the box beside the Code Interpreter option.

5. Save the GPT

  1. After you complete the bot creation and configuration, click on the Save button.
  2. Then, choose with whom you want to share your chatbot. Under the 'Publish to' drop-down menu, select the right option among:
  • Only me: Only you can use the GPT bot.
  • Only people with a link: People with whom you manually share the bot link can access it.
  • Anyone at [Your Copany]: If you are using the ChatGPT Enterprise plan, you can share the bot with your team members.
  • Public: Anyone with a ChatGPT Plus subscription can search and use it from the GPT store.

3. Finally, click Confirm.

6. Share the GPT

If you have decided to share your GPT with others, here is how you can do it:

  1. Navigate to the sidebar and click on Explore
  2. Now, select the GPT you want to share.
  3. Then, click on the down caret beside your chatbot's name and select Copy link from the list of options.
  4. Simply share the link.

By leveraging these advanced features, you can create a custom GPT that goes beyond essential text generation and becomes a powerful tool for automation and integration.

But wait - sometimes a ChatGPT Plus subscription is not available

There was a halt on new ChatGPT subscriptions recently, which has since been reverted. However, at such times when you try to upgrade your ChatGPT subscription to ChatGPT Plus, your only option right would be to sign up for the waitlist.

Although it has now resumed. You absolutely cannot create your custom chatbot without a subscription and neither can you use someone else's custom GPT without having a subscription yourself.

Custom GPT limitations

  1. You cannot try the tool without a subscription - There are no free trials to experiment with the tool until you make the purchase.
  2. Data hallucination - Unless you are training it using integration with specific tools, there will always be chances for data hallucinations. You cannot monitor these interactions if you make your bot public.
  3. Accuracy and source dependence - While ChatGPT can produce detailed content quickly, users may copy and paste information from other sources, raising questions about originality and accuracy.
  4. Limited use case - You can create specific use cases. However, there are limitations in how you incorporate them for business use cases.
  5. Unique and proprietary challenges - The widespread availability and replicability of Custom GPT applications may lead to perceptions that they lack uniqueness or proprietary characteristics. This challenge raises questions about the originality and distinctiveness of custom models.
