Microsoft 365 features that help users manage their subscriptions, account settings, and billing information.
According to this support document: https://support.microsoft.com/en-us/microsoft-365-copilot/ai-credits-and-limits-for-microsoft-365-subscriptions.
Upgrading from Microsoft 365 Personal, Family, or Premium to Microsoft 365 Pro gives you Microsoft’s highest Copilot usage limits.
I do want to point out though, that there are two kinds of limits:
AI credits is consumed by Copilot features inside apps such as Word, Excel, Outlook, Designer, Paint, etc.
Feature limits, are separate limits for things such as Copilot Actions, Vision, advanced models, and other Copilot features.
