When to choose Adobe Firefly
Firefly is Adobe's AI image suite trained on licensed Adobe Stock content, making it the default for brands that need legal indemnification — and it powers Generative Fill in Photoshop.
Firefly wins on one axis that matters to businesses: legal safety. Enterprises with brand-risk lawyers pick Firefly; everyone else picks it because Generative Fill lives in Photoshop.Read our full Adobe Firefly review →
When to choose Stable Diffusion
Stability AI's open-weight models (SDXL, SD3.5) power thousands of apps and can run locally with full control — LoRAs, ControlNet and fine-tuning make it the tinkerer's platform of choice.
Stable Diffusion is the right choice when control matters more than convenience — product shots with ControlNet, brand-tuned LoRAs, private local generation. Casual users should use a hosted tool instead.Read our full Stable Diffusion review →
