Adobe's generative AI-powered Firefly tools are now commercially available to subscribers, but with a catch: Adobe will "charge" you for using it with a credit plan that you may need to pay separately for. Adobe Firefly is a superb AI art generator, trained on Adobe's own stock images. While Firefly is now available for free as a standalone tool, Firefly-powered generative AI art capabilities were added to Adobe Photoshop in May and to Adobe Express last month. Firefly not only generates its own AI art, but can be used as a source for editing: replacing the background on a beach scene with a fantasy castle, for example. Firefly, like other AI generators, is a text-to-image tool which generates an image based on your text description and filters.
