Flux2

Flux 2 is Black Forest Labs’ AI image generation and editing suite built for creating photorealistic images fast. Use it in your browser to generate images from text prompts, or upload an existing image and transform it with natural-language instructions.

Key features include text-to-image and image-to-image editing, support for multiple aspect ratios (21:9, 16:9, 4:3, 1:1, 3:4, 9:16), and the ability to use multiple references (1–8 images) for more guided results. You can also compare examples using a before/after style workflow.

Flux 2 is a great fit for creators, marketers, indie founders, and small teams who need strong visuals quickly—without learning complex design software. It’s also useful for designers who want rapid ideation and concept exploration before moving into production.
