OpenAI's Debut GPT Builder: What Amazing AI Applications Can You Create with It?

In the numerous new features announced by OpenAI CEO Sam Altman at the company's first developer conference, DevDay, one of the most important is likely the new GPT Builder. This tool, which is being rolled out gradually to subscribers of ChatGPT Plus and ChatGPT for Enterprise, allows users to create their own GPT by simply inputting commands in English. These GPTs are essentially AI agents based on OpenAI's new GPT-4 Turbo model. This provides the possibility for anyone, even non-technical users or those without formal development training, to build their own AI agents and applications in a matter of minutes. These third-party GPTs can reference user-uploaded documents and materials and perform specified repeatable actions. They can even access other applications, such as searching for calendar conflicts and automatically sending messages to other meeting participants (as demonstrated on stage by Zapier). OpenAI states that it will offer third-party GPTs in the GPT Store and share the revenue generated with creators. While the GPT Builder is not widely available yet, a few users have already gained early access and report that it is indeed easy, fast, and does not require any prior coding knowledge or development training to build third-party GPTs. Here are some examples of early GPTs that users have built: Product Prototype Using ChatGPT's browsing capabilities and its integration with OpenAI's new DALL-E 3 image generator, Ethan Mollick, a professor at the Wharton School of the University of Pennsylvania and an AI influencer, shared a video on X (formerly known as Twitter) showcasing his GPT called "Trend Analyzer." It can find market trends in specific domains and create prototype images of new products for users to design or pursue in real life. "This is a small GPT (the name for the new kind of agent OpenAI released) that I put together in under a minute. It looks up the latest trends in a product category online and creates prototype images for it. Less than 90 seconds from start to finish." - Ethan Mollick (@emollick) Simpsonize Me GPT Another new GPT, called "Simpsonize Me GPT," was created by Matt Schlicht, CEO of Octane AI. It utilizes the image generation capabilities of DALL-E 3 and the new "All Tools" mode of ChatGPT to reference user-uploaded images and automatically apply a prompt to transform their personal photos into cartoon-style images reminiscent of Matt Groening's long-running animated comedy series, "The Simpsons." Schlicht wrote that he built it in "under 10 minutes" using OpenAI's new ChatGPT Builder. "Introducing: Simpsonize Me GPT! 1. Upload your personal photo. 2. Simpsonize Me GPT turns you into a character from The Simpsons. I built this in under 10 minutes using OpenAI's new ChatGPT Builder." - Matt Schlicht (@MattPRD) Maximizing Social Networking Rowan Cheung, an AI influencer and creator of The Rundown AI newsletter, created the X Optimizer GPT on X (formerly known as Twitter). It automatically analyzes the text he posts on his X account and suggests improvements and optimal posting times for maximum engagement. "Just tested the new GPT Builder from OpenAI. Created 'X Optimizer GPT' that fine-tunes my posts and finds peak posting times for maximum engagement on X. The results are mind-blowing." - Rowan Cheung (@rowancheung) Create Animated GIFs with Gif-PT Using the image generation capabilities of DALL-E 3, developer and former Twitter employee Nick Dobos created a new GPT called "Gif-PT" on his X account. It automatically applies appropriate prompts to create multiple image grids and converts them into frames. Using ChatGPT's advanced data analysis mode, the code interpreter, he wrote Python code to convert the frames into a single animated GIF that users can download. "Played around with the new ChatGPT custom GPT. Introducing: Gif-PT, which automatically converts DALL-E images into GIFs. Here's a quick demo, still a work in progress." - Nick Dobos (@NickADobos) Although Dobos acknowledges that the results may be inconsistent and "rough," considering the amount of effort put in and the fact that it is similar to Meta's own AI-powered animated sticker generator but made by just one person in possibly only a small amount of time, the results are still impressive. He later tweeted that he was "very impressed." Teaching and Stress Relief The first customizable GPT showcased by OpenAI CEO Sam Altman in his DevDay keynote speech, built on stage in about five minutes, is a coaching GPT for tech company founders based on advice he received from venture capitalists and his own recommendations. So, some of the earliest third-party GPTs follow this pattern as well. Two examples include a product teaching GPT created by Yana Welinder, CEO and founder of Kraftful, and a daily stress relief GPT created by Mustafa Ergisi, founder of ai2sql. Welinder's GPT provides practical strategic business advice, such as how to improve user retention and how to organize case studies of sample products, while Ergisi's GPT offers mindfulness exercises and suggestions for cultivating better sleep habits. "This is what it can do: Ask it how to improve user retention." - Yana Welinder (@yanatweets) "Just tested the new GPT Builder from OpenAI. Created 'Daily Stress Relief GPT.' It provides daily wellness tips and personalized mindfulness exercises. I'm blown away." - Mustafa Ergisi (@mustafaergisi) Of course, these are just the first few GPTs developed by third parties after OpenAI announced its new GPT Builder. There will be more GPTs in the future, potentially with more features and capabilities than these initial ones. This wave of third-party GPTs marks a strong start for the GPT Builder, GPT Store, and OpenAI's ambition to become the Apple of the mobile field.
