FLUX Erase is a dedicated image editing model from Black Forest Labs for removing unwanted objects, text, or distractions from an image while reconstructing the surrounding content naturally. It is tuned for erase-style workflows where the goal is not to replace an element with something new, but to leave a clean, coherent result that matches nearby structure, lighting, texture, and scene context.

FLUX Outpainting is a dedicated image expansion model from Black Forest Labs that extends an existing image beyond its original borders in a single call. It is tuned to continue scene content, lighting, texture, and composition naturally without requiring a text prompt, making it useful for aspect-ratio changes, social reformats, banner layouts, and other canvas-extension workflows.

FLUX.2 [klein] 9B KV is a KV-cache optimized variant of the Klein 9B model that caches reference image key-value pairs after the first denoising step, skipping redundant computation on subsequent steps. This delivers up to 2.5x faster inference for multi-reference editing tasks while retaining all capabilities of the standard Klein 9B, including sub-second text-to-image and advanced editing in 4 steps.

FLUX.2 [klein] 9B is a 4-step distilled image generation and editing model designed for sub-second inference without sacrificing visual quality. It unifies text-to-image and advanced editing workflows in a single model, making it suitable for interactive applications, real-time previews, and latency-critical production use.
