Overview of GPTs in the AI Landscape

GPTs are powerful AI models pre-trained on vast amounts of data and can generate human-like text. ChatGPT is the most common example. GPTs understand and generate coherent and contextually relevant responses, making them invaluable in applications such as chatbots, content creation, and more.

GPTs can be trained on specific tasks or information, such as your own blog posts or company documents. In this way, custom GPTs can be a faster, more consistent way to use AI than logging in to ChatGPT.

Let’s learn why GPTs matter. Then, we’ll dive into essential details about GPTs.

The Importance of GPTs

GPTs are the most common entry point into AI. Learning the basics of GPTs will help you identify the best ways to use AI to work smart and live well, as we often share on FiveMin.AI. Further, by understanding the differences between GPT models and other AI approaches like Assistant's API, you can choose the best way to use this technology for your use case.

GPTs play a significant role in the AI landscape. Learning how to use GPTs, especially when customized for your use case, will save you time and help you improve your output. As one MIT study published in Science shows, using GPTs increases productivity 40% and improves quality 18%, particularly for less skilled, newer, or generally lower performers.

In short, GPTs are a floor raiser. You can increase quality across the board when you build a specific, well-trained GPT.

Let’s decide how to build your GPT in the next section as we explore the differences between building a GPT directly on ChatGPT and building with OpenAI Assistant’s API.

GPT vs. Assistant's API: Understanding the Difference

OpenAI's offering of GPTs and the Assistants API have revolutionized the development and deployment of AI-based applications. Understanding their differences is crucial for developers and businesses looking to harness their capabilities effectively.

Technical Distinctions: Architecture and Functionalities

GPTs created in ChatGPT and the Assistants API are built on similar underlying technology but offer distinct functionalities and architectures.

GPTs built within ChatGPT are specialized versions of ChatGPT that can be customized for various tasks or topics, integrating different instructions, knowledge, and capabilities.

This customization is accessible through a user-friendly interface, allowing both simplicity and complexity in the application as required. The main charm of GPTs lies in their ease of creation (no coding required) and their operation within the ChatGPT environment, making them ideal for tasks ranging from language learning to technical support.

On the other hand, the Assistants API is designed for developers and businesses who wish to bring AI assistants into their own applications.

It provides functionalities like Code Interpreter, File Retrieval, and function calling. A significant feature of the Assistants API is its ability to handle persistent and infinitely long chat history ‘threads’, enabling builders using the Assistants API to manage thread state more efficiently and overcome context window limitations. The Code Interpreter allows the execution of Python code in a sandboxed environment, generating graphs and charts, and processing files with diverse data. File Retrieval augments the assistant with external knowledge, optimized using techniques based on OpenAI's experience with knowledge retrieval in ChatGPT.

Use Case Scenarios: When to Use GPTs vs. Assistant’s API

GPTs are best suited for applications where a simple UI and a non-coding approach are preferred.

Their integration into ChatGPT makes them ideal for Plus and Enterprise users - a paid account is required to use them - who need task-specific AI solutions without bringing the experience into their own applications, business dashboards, or other internal interfaces. They can address many applications but are bound to the ChatGPT ecosystem.

In contrast, the Assistants API is tailored for developers and businesses seeking to incorporate AI assistants into their products or services.

Its flexibility and the wider range available for integration make it suitable for more complex applications, such as natural language-based data analysis apps, embedded AI assistants, or AI-powered customer service solutions. The Assistants API is particularly valuable when there's a need to integrate proprietary domain data or user-provided documents, enhancing the AI assistant with a broader knowledge base and specific functionalities to meet your specific business or organization’s needs.

The choice between GPTs and the Assistants API depends largely on the application’s specific needs, the flexibility required, and the desired level of integration and scalability. Each offers unique advantages that cater to different aspects of AI application development and deployment.Let’s take a look at some best practices when building GPTs.

How to Build a GPT

Now that you know how GPTs can be used, let’s go through the step-by-step process of building a GPT. This includes developing and training it with a prompt to deploying it using different platforms. We will also discuss the long-term operational considerations for maintaining and optimizing GPT performance.

Start with the Prompt - Training Your GPT

The first step in building a GPT is to define a prompt. A prompt is the instructions you give the AI for how to behave.

The prompt can include your specific questions - e.g. write me a blog post - but it should also set the context for how the AI should behave.

To create an effective prompt, you can use the RIPE framework:

  • Role: Define the role or objective of the GPT. What specific task or problem do you want it to address?
  • Inquiry: Craft a clear, concise question or prompt that the GPT will respond to.
  • Parameters: Specify any additional parameters or constraints for the GPT, such as word count or formatting requirements.
  • Example: Provide an example or demonstration of the desired output to help the GPT understand the expected result.

This video shows the RIPE framework in action to help you create prompts to write grants.

Testing Prompts in a GPT

A well-designed prompt helps the GPT generate accurate and relevant responses.

The best way to create better prompts is to experiment! You can create a prompt, test your GPT, and then edit the prompt based on the results.

You can also save time by learning from the prompts of others. Chipp offers a Prompt Library here where you can copy and paste prompts for specific use cases. Then, just edit the prompt to fit your needs. For example, this tutorial video shows how to use this prompt to create projects in a classroom.
