An Adobe Firefly alternative, inside Photoshop
Nano Banana, GPT-Image-2, FLUX.2, Reve, Seedream, and Imagen in one Photoshop panel. Every result is a normal layer in your open document.
Generative Fill is built into Photoshop and is quick for small fixes. Seam is a complete plugin next to it: model choice, 4K output, reference libraries, your own LoRA styles, and dedicated upscalers.
