There are two different AI editing paths in Microsoft Photos, and the limits depend on which one is being used:
- Photos app local AI editing like Generative Erase runs locally on the device. No free photo-count limit or paid add-on price is stated for that feature in the provided information.
- Edit with Designer in Microsoft Photos is an online AI experience and requires an internet connection. To use its AI features, a Microsoft account sign-in is required.
For usage limits and paid options, the available information points to Microsoft 365 subscription AI limits rather than a per-photo price:
- Microsoft 365 Personal and Family include standard usage for Image gen.
- Microsoft 365 Premium and Pro include extensive usage for Image gen.
- Microsoft states these are usage caps that can vary by feature, entry point, and system conditions, and can change over time.
- Usage is tracked automatically, and notifications appear when approaching or reaching a limit.
No fixed “number of photos for free” and no direct price per additional photo is provided in the available information.
