AI Create Image

@Lencyn Adobe Firefly, works best with descriptive text prompts. There isn't a fixed "list of commands" in the traditional sense, but rather a focus on using natural language to describe what you want. The more specific you are, the better the result. Instead of a general prompt like "beach sunset," try "sun setting in the background of a sandy beach with ocean waves crashing on the shore." Focus on describing the object or scene, not giving instructions. For example, use "blooming red rose" instead of "create a flower." 

For the second question, the Generative Fill feature doesn't create images with a transparent background on its own. It places the new content on a generative layer, which still has a background. To get a transparent background, you need to use another Photoshop tool, such as the "Remove Background" quick action, on the generated layer. After removing the background, you can then save the file as a PNG or PSD to preserve the transparency.
