Adobe began integrating Firefly into the beta versions of Photoshop in May, introducing the Generative Fill feature. This function allows users to select an area of the image that needs to be replaced, then enter a text description of the content they want to generate in its place. Photoshop then creates AI-generated content as a separate layer based on the provided description.

Generative Expand is a similar tool, but instead of insertion, it utilizes an expansion approach, so it doesn't replace the image area but extends the boundaries of the existing one.
The user can expand the canvas using the existing Crop tool and then enter a text description of the new background they would like to generate. The AI-generated content is created, and it is not seamlessly placed on a new layer.
For more detailed information about Adobe's approach to generative AI, including how the company gathers images to train its generative AI models, you can find it in the FAQ for artists regarding Firefly.

Photoshop 25.0 is the first instance where Adobe has assigned its own version number to a beta version of the software. The stable release, Photoshop 24.7, represents a relatively modest update primarily focused on fixing issues reported by users.

Photoshop 25.0 is a beta version of the software that can be installed through the Adobe Creative Cloud application. Adobe has not specified when the new artificial intelligence features will be available in the stable release.

Photoshop 24.7 is available for Windows 10 and above and macOS 11.0 and above, accessible only through a subscription. The subscription cost for photographers, which includes access to Photoshop and Lightroom, starts at $119.88 per year. The subscription cost for a single application like Photoshop is $31.49 per month or $239.88 per year.
