Flux 2 is a free AI image generator and editor from Black Forest Labs that creates photorealistic images from text prompts and edits existing images using natural language instructions.
What is Flux 2?
Flux 2 is Black Forest Labs’ next-generation image generation and editing suite. It accepts text prompts or uploaded images as input and outputs photorealistic images up to 4 megapixels. The tool runs in the browser with no download required and supports multiple aspect ratios, model variants, and multi-reference blending.
Key Features
- Text-to-Image & Image-to-Image — Generate images from detailed text prompts or transform an existing image using a new description.
- Natural Language Editing — Upload any image and describe changes in plain English; Flux 2 edits the image while preserving original context and quality.
- Multiple Aspect Ratios — Choose from 21:9, 16:9, 4:3, 1:1, 3:4, and 9:16 for wallpapers, social media stories, or standard prints.
- Flux Kontext Pro & Max Models — Pro generates balanced results in ~30 seconds; Max delivers higher detail for complex scenes and takes slightly longer.

- Credit-Based System — Each generation consumes credits (e.g., “Flux 2 Pro Balanced — 30 credits”); paid plans extend usage beyond the free allowance.
