Firefly is trained with images from Creative Commons, Wikimedia and Flickr Commons as well as 300 million images and videos in Adobe Stock and the public domain.

It was initially released as a public beta in March 2023,[9] and is currently available to all Adobe Creative Cloud subscribers.

Sensei has been used to power a variety of features in Adobe's creative software, such as object selection in Photoshop and image auto-enhancement in Lightroom.

Firefly expanded its capabilities to Illustrator, Premiere Pro, and Express, particularly for generating photos, videos and audio to enhance or alter specific parts of the media.

[10] Google planned to use Firefly in Bard (now Gemini) as its AI image generator, but ended up using their own Imagen model.
