How to Build and Publish Custom GPTs in OpenAI’s Custom GPT Store
This article explains how to create a custom GPT assistant using OpenAI’s no‑code builder, configure multimodal features, and publish it on the upcoming Custom GPT Store to share or monetize the assistant, with step‑by‑step instructions and target user scenarios.
On January 5, OpenAI announced the upcoming Custom GPT Store, a marketplace where developers can share or sell their custom ChatGPT assistants, similar to an app store for large language models.
Custom GPTs are built without any code through a visual interface; users provide prompts, knowledge data, and optionally enable multimodal capabilities such as web browsing, data analysis, and image generation.
The guide walks through the entire creation process: logging into a Plus account, entering the "Explore" section, clicking "Create a GPT", describing the assistant’s purpose, uploading additional data, naming the assistant, generating an avatar with DALL‑E 3, and configuring features like Web Browsing, DALL‑E, and Code Interpreter.
After building, developers choose whether to keep the assistant private for internal use or publish it publicly in the Custom GPT Store to earn revenue; the store includes a ranking system based on usage.
The article also outlines ideal users for custom GPTs, including researchers needing domain‑specific knowledge assistants, teachers creating educational bots, and product managers building assistants to analyze user feedback and support rapid product iteration.
Overall, the Custom GPT Store provides a no‑code, multimodal platform for anyone with quality data to create and monetize specialized AI assistants.
