Can M365 Copilot Business Users Still Use GPT Builder for Custom GPTs?

Hi everyone,

I've come across some conflicting information and I need some clarity. I'm a Microsoft 365 Copilot Business user and I'm trying to figure out if I can still use the GPT Builder to create custom GPTs.

From what I understand, only the consumer version, "Copilot Pro," has had the GPT Builder functionality shut down. Here's what I've gathered:

• Copilot Pro: This subscription is tied to a simple Microsoft account and is primarily for private users. Microsoft has indeed disabled the GPT Builder for these users.
• Copilot for Microsoft 365: This can be added to a Microsoft 365 Business account on a per-user basis. From my understanding, business customers can still utilize the GPT Builder.

Currently, when I try to create a custom GPT via the web interface as a business user, I no longer see the option available, similar to the experience of private consumers.

Could anyone confirm if as a Microsoft 365 Copilot Business user, I still have access to the GPT Builder for creating custom GPTs? Any official documentation or personal experiences would be greatly appreciated! 

Thanks in advance!
