It operates via a dedicated panel inside Photoshop. You select an area, type a prompt, and the AI generates new content, fills selections, or expands the canvas. While "text-to-image" is common now, Alpaca focuses on workflow integration . 1. "Imagine" (Text-to-Image) The bread and butter. Type a prompt, select a region, and Alpaca generates variations directly on a new layer. Crucially, it respects your existing composition's lighting and color if you use the "reference" options. 2. "Scribble" (Conditional Control) This is the killer feature. You can quickly sketch a rough shape or color block with your mouse, then ask Alpaca to "render" it. For example, draw a red circle, type "leather apple" , and the AI transforms your scribble into a photorealistic object. This gives you far more layout control than Firefly. 3. "Depth" & "Pose" (ControlNets) Alpaca integrates ControlNet natively. You can generate a character, lock in a specific pose (via OpenPose), or preserve the depth of a room while changing the entire style. Native Photoshop AI cannot do this yet. 4. "Outpainting" (Expand Canvas) Similar to Firefly’s generative expand, but with model variety. You grow your canvas borders, and Alpaca fills the void. It works exceptionally well for turning portrait shots into wide landscape scenes. 5. "Upscale" A 4x upscaler built directly into the plugin. Instead of jumping to Topaz or Gigapixel, you can right-click your generated layer and upscale it instantly.
