What Are Custom GPTs?

Custom GPTs are specialized versions of ChatGPT configured with custom instructions, uploaded documents, structured workflows, and optional integrations with external tools or APIs. Unlike general-purpose chatbots, the best custom gpts are optimized for specific outcomes, such as writing SEO content, answering customer questions, analyzing data, or supporting internal teams.

Custom GPTs are available through the GPT Store, where users can browse, test, and deploy them instantly. For businesses, Custom GPTs can also be built privately using internal data, enabling AI assistants that understand company terminology, processes, and policies.
