How to Publish and Share a Custom GPT

Once a custom GPT works for you, sharing it lets teammates or the public use it too. The choices matter: who can see it, whether your name appears, and how updates roll out. This guide covers publishing safely and the housekeeping that keeps a shared GPT trustworthy.

What you need

• A custom GPT you built and tested
• A clear idea of your audience (just you, your team, or anyone with the link)
• A verified builder profile if you plan to publish publicly

Step 1: Open the sharing options

Open your GPT, click Edit GPT, then the Share or Create button in the top right. A visibility menu appears with the available audience levels.

Step 2: Pick the right visibility

Choose the narrowest option that meets your need. You can widen it later, but you cannot un-share something a user has already opened.

Step 3: Review what gets exposed

Before sharing, remember that users can often surface your instructions and knowledge file contents through clever prompting. Remove anything private from both, and if the GPT uses Actions, double-check it does not leak credentials.

Step 4: Update without surprises

To change a published GPT, edit it and click Update. The same link keeps working and users get the new version automatically. Note what changed in the description so returning users understand any new behavior.

Result

Your GPT is live at a stable link with the right audience, no private data exposed, and a clear path to ship updates that reach everyone instantly.
