Read the full Flux review

Flux by Black Forest Labs is the strongest open-weight image model available. It follows prompts precisely, renders humans and hands convincingly and handles text in images better than most closed models. Because the weights are open, you can run Flux locally, fine-tune it on your own style or embed it inside a product without per-image fees. For developers and designers who need control and portability, Flux is the default open choice.

Leonardo AI packages several strong image models behind a workflow tailored to designers, game artists and marketers. Its Realtime Canvas, custom-trained models and controllable image-to-image features stand out. A generous free tier and a large community of fine-tuned models make it a practical choice for daily creative work at a lower cost than Midjourney.
