Custom GPTs are not only as good as you want them for customer support; they can also help you extend the automation capacity for dozens of activities, such as generating content, scheduling meetings, and updating content. However, this is only effective when you build a custom GPT with your company’s proprietary data. ChatGPT’s premium version is one such option for you to build a custom GPT.

However, sooner or later, you can find some limitations only to prevent you from building improved customer relationships or stakeholder experience. 

A scalable custom GPT builder, PagerGPT, can seamlessly enhance the productivity and efficiency of your employees and boost customer experience. With PagerGPT, you don't have to manually configure all fields to construct your AI assistant or deal with lingering design issues like ChatGPT custom options.

So, if custom GPTs are a way to go for your enterprise or business-specific goals, especially for customer support, HR, or IT support, we’ll show you how easily you can build your custom GPT, enhance automation for user interactions, and solve problems at scale. 

In this blog, we’ll explore a step-by-step guide to building your custom GPT bot with PagerGPT and explain why ChatGPT’s custom GPT is not a practical solution for enterprise needs. 

What are Custom GPTs?

In a very simple term, custom GPTs are personalized AI assistants that train on massive company proprietary datasets to generate human-like responses for business-specific questions and solve problems. 

For example, when you want to build your custom GPTs for financial services, you want your AI assistant or GPT bot to generate coherent and contextually relevant responses related to your products and solutions, which is otherwise a massive headache if you use just a pre-existing bot like ChatGPT. So, when a user asks, “How to make a withdrawal to a bank account”? Your custom GPT bot can easily give a response to this product-specific question.  

Basically, custom GPTs are a specialized version of the existing GPT model developed by OpenAI. If you want to build your custom GPT, you can use the ChatGPT enterprise version. Ask the GPT builder what you want to create and provide the prompts or manually configure. You are set to build anything from an AI interview assistant, skill development trainer, gaming coach, or any productivity tool like an image creator or code-generating tool. You can create with your data, and it’s ready to go.

How does Custom GPT work?

GPTs usually use their existing data to surface responses through self-attention or self-learning. However, building GPT models for specific tasks requires fine-tuning language models. 

The essential inner workings of GPTs consist of a few steps, 

  • Data processing using transformers: Generative Pre-trained Transformers, or GPTs, process data using their core architecture transformer, which uses deep learning to understand and generate human-like texts. 

  • Self-learning through machine learning algorithms: Machine learning algorithms also help LLMs identify patterns from interactions, self-learn to adapt to different contexts of sentences, and generate human-quality sentences.

After you fine-tune your GPT model, it follows a unique process along with the existing one.

  • Third-party or domain-specific data training for unique questions: Fine-tuning the LLMs involves exposing GPTs to third-party or company-proprietary data to improve understanding for accurate and contextual answers. 

  • Predefined rules and instructions: LLMs are instructed and applied with predefined rules to guide their responses.

  • Integration with business system: GPTs can use APIs or connectors to integrate with existing chatbots, knowledge bases, or other data resource systems.  

Advantages of Custom GPTs

Pre-trained GPTs lack significant competencies to deliver business outcomes. Custom GPTs can meet enterprise needs and help leaders harness unique benefits. 

1. Multiple GPTs for different use cases

With ChatGPT’s paid versions, you can create as many GPT bots as you want, depending on your needs. You can create a support bot, an online tutor, or an email generator and toggle between them to get the right kind of support when needed. 

2. Easy response configuration

A GPT builder lets you connect to your knowledge bases and train its model to generate intended responses. There is no manual iteration of copying and pasting data and training the bot. It’s that simple. 

3. Automating customer support 

Custom GPTs are better at handling FAQ-type questions, even unique queries, and free human agents to focus on strategic work. 

4. Enhancing knowledge management 

Custom GPTs can summarize chat history, help create new responses, and update existing ITSM knowledge resources or help docs. 

5. Efficiency and automation

Your service desk can handle many questions using GPTs by automating responses and streamlining repetitive tasks. 

6. Consistent responses

Quality training data ensures communications across the customer support channels are uniform and consistent for various users. 

7. Scalability 

Whether the volume of queries increases, custom GPTs can handle the growing number of queries quite efficiently and reduce the need for extra resources.
