FLUX 3 is the flagship model from Black Forest Labs, a company founded by the creators of Stable Diffusion. Compared to FLUX 2, it renders skin, fabric and material texture noticeably better, builds cinematic lighting, and draws hands and anatomy correctly. FLUX 3 is the model to pick when you need an image that looks like the work of a professional photographer.
The model reads long prompts closely. Write "portrait of a middle-aged woman with curly red hair, wearing a blue wool sweater, by a café window, soft daylight, film photography" and you'll get exactly that, with every detail intact.
FLUX 3 doesn't just generate — it edits too: in FLUX 3 Edit mode you can upload up to 10 photos and change the scene while keeping the original's light and texture. Generation takes 30–80 seconds and costs 6 credits per image.
For drafts and batches there's FLUX 3 Klein, a fast version of the model. It responds in seconds, produces up to 4 variants per run, can also edit photos, and costs 2 credits per image.
