The GPT Store is OpenAI's public directory of GPTs inside ChatGPT. A GPT, also called a custom GPT, is a version of ChatGPT configured for one purpose. It combines instructions, conversation starters, uploaded knowledge files, selected capabilities such as web search or image generation, and either apps or actions that call external APIs.
Users find GPTs under Explore GPTs or through a direct link; anyone signed in to ChatGPT can chat with a GPT they have access to, and builders cannot see individual conversations. To publish to the store, a builder chooses a category, reviews how the builder name or website appears, and confirms that the GPT meets the applicable policies.
OpenAI is retiring custom GPTs and moving their workflows to plugins. Personal accounts (Free, Go, Plus and Pro) can no longer create or publish new GPTs. The standard retirement date is December 11, 2026; after it, custom GPTs stop running and leave the GPT directory.
