FLUX.2 [flex] is an image generation and editing model from Black Forest Labs that gives developers full control over quality-speed trade-offs through configurable parameters such as sampling steps and guidance scale. It supports text-to-image generation, image editing, and multi-reference composition at resolutions up to 4 megapixels, all within a single unified architecture. With its wide stylistic versatility and strong compatibility with LoRA adapters, Flex is well-suited for creative exploration, rapid iteration, and custom fine-tuning workflows.
