How to Use @mentions
When you're chatting:
Type
@to open an inline menu showing your recent and pinned GPTs.Select a GPT from the menu to direct your next message to that GPT.
The conversation will retain its current context, even when switching between different GPTs.
This allows you to easily bring in different GPTs — each with their own skills, styles, or custom instructions — without needing to start a new chat. It’s great for streamlining workflows that involve multiple tools or personas.
Enterprise Workspace Notes
If you're part of a ChatGPT Enterprise workspace:
Some GPTs may appear grayed out if they are restricted by your workspace settings.
GPT availability and access can be managed by your workspace Owner or Admin.
