ChatGPT is an incredibly knowledgeable AI tool. It commands competence across several fields. It can respond to queries on just about any topic—technology, business, history, sports, arts—you name it. However, generative AI tools are only as good as the data they were trained on. Although ChatGPT was trained on a very extensive dataset, there are still huge gaps in its knowledge base. The AI chatbot lacks specific information on certain topics, especially in niche areas where data is scarce.

Say, for instance, you’re running a small business, and use ChatGPT for business planning, how much would ChatGPT know about the dynamics of your business? If you're integrating ChatGPT into your customer support service, how much would ChatGPT know about your company and product? If you use ChatGPT to create personalized documents, how much would ChatGPT know about you?

The short answer? Very little. In these cases—and more, ChatGPT will be lacking in its ability to help because it likely won't have enough data about you or your business. Data is the lifeblood of ChatGPT and without enough of it on any subject, ChatGPT isn't any better than a book missing crucial chapters.

You can solve this knowledge gap problem by training ChatGPT with your data. To make ChatGPT compete in niche areas, you'll need to train it on those subjects. But how?

Well, there are two efficient ways to do this:

  1. Using ChatGPT Custom GPTs
  2. Using Chatbase

We'll go through each option to see which one works for you.

Using ChatGPT Custom GPTs

Custom GPTs are like mini programmable versions of ChatGPT you can train on specific tasks. You can think of them as a way to boost ChatGPT's knowledge on a certain subject by providing data relevant to that subject.

Suppose you want ChatGPT to help you in making tricky business decisions, you can create a Custom GPT, upload your business data, and let the AI chatbot use a combination of that data and its extensive expertise to help you take the right steps.

How to Train ChatGPT with Your Data Using Custom GPTs

To create a Custom GPT, the first step is to sign up for a ChatGPT Plus subscription at if you don't already have one. A Plus subscription currently costs $20 per month (note that subscriptions are temporarily suspended at the time of writing).

Once you have a Plus subscription:

Step 1: Create a New GPT and Provide Base Instructions

1. Go to and log into your Plus account

2. Click Explore on the left-side menu. This will bring you to the "My GPTs" page.

3. On the page, click Create GPT, and the GPT builder page should come up. This is where you will set up your GPT by giving it a purpose, uploading data, and training it.

4. On the GPT builder page, provide a name and description for your model to define its purpose. For this guide, we will be creating a GPT to help guide customers through the process of renting a car from a local rental agency called ChicCars.

5. In the interactive editor, you will need to provide a prompt to the GPT builder by describing exactly what the GPT will be doing. We will be using the prompt “I'd like you to serve as a knowledgeable advisor, assisting customers in choosing the ideal rental cars. Your role is to steer them towards decisions that benefit both the company and the customer, ensuring the best possible choices.

6. Provide any additional information that you feel is necessary for the GPT builder to know more about what you want it to do.

7. Tap the Configure button on the top of the interactive GPT builder to reveal the configuration options. You can change the name of your GPT or provide additional instructions here.

Step 2: Upload Training Data and Test Your Chatbot

1. Scroll down to the bottom of the configuration options and click on Upload files to upload the data needed to train the GPT. For this demonstration, we uploaded a text file with data on ChicCars.

2. Click the Save button in the top right corner when you have finished uploading data. Select the desired visibility for your trained GPT, such as Only people with a link, and click Confirm to finalize creating your trained Custom GPT. This should synchronize the data you uploaded with the interactive GPT builder.

3. Click "View GPT" in the drop-down menu that comes up to start interacting with your trained model.

4. Ask the trained model a question on the subject you trained in to see the results.

Limitations of Custom GPTs

Creating a Custom GPT is a straightforward way to build an AI assistant tailored to your needs, without requiring any coding. By training an instance of ChatGPT with your data, you can deploy a specialized chatbot in just minutes. However, these custom models do come with limitations.

  1. Poor brand integration: Custom GPTs don't naturally incorporate your brand's visual identity, slogans, logos, or other elements that uniquely define your image. This makes it difficult to maintain a consistent brand experience when deploying a Custom GPT.
  2. Integration challenges: relying on Custom GPTs as a low-code or no-code solution for business tasks like customer support chatbots may not deliver desired outcomes. There are uncertainties around how to seamlessly integrate a Custom GPT hosted on ChatGPT's platform into your own business workflows, operations, and touchpoints.
  3. Access barriers: to use your Custom GPT chatbot, customers would need their own ChatGPT Plus account. This added friction means you can't rely on it as a scalable customer support channel if customers don't have accounts.
  4. Data privacy risks: any training data used for your Custom GPT could potentially be accessed by anyone with a link to the model, allowing sensitive business or personal data to be revealed.
  5. Data security issues: by default, OpenAI may utilize conversation logs from Custom GPT deployments to advance its own AI models. This means proprietary business data or personal info could enter the public domain through OpenAI's model training pipelines.

How do you deal with these limitations? How do you ensure that you are in control of the data you share with your customers? One of the most efficient ways to train ChatGPT with your data–and without the baggage that comes with using Custom GPTs–is using Chatbase. But what is Chatbase and how can it help you train ChatGPT with your data?
