Adobe Firefly is the safe choice for commercial work. Because it is trained on licensed Adobe Stock and public-domain content, Adobe positions its output as commercially safe, which matters for brands and agencies wary of the copyright questions hanging over models trained on scraped data.
Its standalone generation is good rather than exceptional, but that misses the point. Firefly's power is inside Photoshop and Illustrator, where Generative Fill and Expand let you edit real photographs with AI. If you live in Creative Cloud or need commercial-use confidence, Firefly earns its place; if you just want the best raw generation, look at Midjourney or Flux.
