Summary
Custom GPTs are specialized, user-defined versions of OpenAI's ChatGPT, designed to perform specific tasks or serve particular domains by incorporating custom instructions, extra knowledge, and external actions. Within the broader AI landscape, they represent a strategic "moat" for OpenAI, as argued by David Sacks in the All-In podcast, leveraging a robust developer platform to maintain market leadership. Since their introduction, the ecosystem has grown rapidly, with over 3 million GPTs created by early 2024, facilitating applications ranging from education and programming to enterprise data analysis and no-code app development. While they offer significant productivity gains, they remain subject to the limitations of their base models, including the potential for hallucinations and misinformation.

ChatGPT is a generative artificial intelligence chatbot developed by OpenAI, and released in November 2022. It uses generative pre-trained transformers (GPTs), such as GPT-5, to generate text, speech, and images in response to user prompts. It is credited with accelerating the AI boom, an ongoing period marked by rapid investment and public attention toward the field of artificial intelligence (AI). OpenAI operates the service on a freemium model. Users can interact with ChatGPT through text, audio, and image prompts. The service gained 100 million users in two months, making it the fastest-growing consumer software application in history. ChatGPT's website is among the top 5 most-visited websites globally. It has been lauded for its potential to transform numerous professional fields, and instigated public debate about the nature of creativity and the future of knowledge work. The chatbot has also been criticized for its limitations and potential for unethical use. It can generate plausible-sounding but incorrect or nonsensical answers, known as hallucinations. Biases in its training data have been reflected in its responses. The chatbot can facilitate academic dishonesty, generate misinformation, and create malicious code. The ethics of its development, particularly the use of copyrighted content as training data, have also drawn controversy.

CustomGPT.ai excels in providing more extensive customization options, greater control over data privacy, and enhanced integration capabilities, making [...] In this guide, we’ve explored two distinct methods for creating custom GPTs: using OpenAI’s platform and leveraging the advanced features of CustomGPT.ai. While OpenAI’s solution offers a way to create custom language models, it comes with certain limitations in customization, data privacy, and cost. On the other hand, CustomGPT.ai provides a more flexible, secure, and cost-effective alternative, making it an excellent choice for businesses and individuals with specific needs.
- Introduction to Custom GPTs - Generative AI at BYU
Custom GPTs are created by OpenAI and community members. Creators can choose the level of visibility for their GPTs, choosing to make them private or publishing them to the public on the GPT store. In January 2024, OpenAI reported that over 3 million custom GPTs have been created. Other sources have reported that over 150k GPTs are public and available in the GPT store. [...] Another powerful feature of custom GPTs is the ability to load files into their knowledge base. The model will refer to these files before it responds to the user, employing a simple form of retrieval-augmented generation. Custom GPTs can also make use of Actions, a framework that allows the model to interact with external sites and services. The use cases for custom GPTs are endless. Some popular applications are programming, document editing, and image generation, among many others. [...] Remember that a custom GPT is simply an instance of ChatGPT with a specific set of instructions. Because of this, it is still prone to hallucinations. When creating your own GPT, you can avoid hallucinations by instructing the model how to appropriately handle prompts that are outside of its scope. However, hallucinations are always possible with even the best-trained custom GPTs.

Custom GPTs provide businesses with the flexibility to automate and enhance various aspects of operations, from customer-facing roles to back-end data analysis. By implementing GPT models tailored to specific industry needs, companies can realize measurable improvements in efficiency and service quality, positioning themselves ahead of competitors. Whether you're looking to deploy an intelligent chatbot or create an internal data analysis tool, the possibilities with custom GPTs are limitless. [...] ## Understanding custom GPTs and their benefits Before diving into how to create a custom GPT, it’s important to grasp what sets them apart. A GPT (generative pre-trained transformer) is a large language model (LLM) that can generate human-like text based on the input it receives. By training or fine-tuning a GPT model to fit specific business needs, organizations can optimize workflows, develop tools, and automate tasks, resulting in increased efficiency and productivity. [...] ## How to make custom GPTs for business impact Creating a custom GPT is more than a technical exercise; it’s a strategic move to enhance business processes and outcomes.

- Introducing GPTs - OpenAI
We’re rolling out custom versions of ChatGPT that you can create for a specific purpose—called GPTs. GPTs are a new way for anyone to create a tailored version of ChatGPT to be more helpful in their daily life, at specific tasks, at work, or at home—and then share that creation with others. For example, GPTs can help you learn the rules to any board game, help teach your kids math, or design stickers.
