An open-source image editing model developed by Black Forest Labs specifically for developers, researchers, and advanced users, supporting LoRA adapters. Kontext can handle both text and image inputs. Using rectified flow architecture, it enables precise editing of existing images through natural language instructions while maintaining character and object consistency across multiple rounds without fine-tuning. Supports style transfer, background replacement, and inpainting.
