Overview

About FLUX Kontext Max

FLUX Kontext Max is Black Forest Labs' instruction-based image model. Its main job is editing: give it one image and say what should change, such as "make the background a sunlit kitchen" or "change the jacket to navy", and it returns a new version that keeps the rest of the picture. Without an input image it works as a text-to-image model.

In Masonry, Kontext Max accepts one input image per edit and outputs PNG or JPG in nine aspect ratios, from square to wide 21:9 and tall 9:21. Exact pixel sizes are snapped to the nearest supported ratio. You can set a seed for repeatable results, adjust guidance (lower values look more realistic), turn on automatic prompt enhancement, and set a safety tolerance from 1 to 6, which is capped at 2 when you edit an image.

Use it when you already have an approved image and need a specific change without rebuilding the whole scene. For edits that combine several reference images, choose a model that accepts more inputs, such as FLUX 3 Image or Seedream 5 Pro.

Prompts behind these FLUX Kontext Max images

Actual prompts from FLUX Kontext Max renders by the Masonry community. Copy any prompt, then remix it into your own creation.

a woman posing against a plain light background, styled in an elegant and minimal fashion. She is wearing a black, deep V-neck top with slightly puffed shoulders, giving her outfit a sophisticated silhouette. Her dark, straight hair is parted in the middle and tucked neatly behind her ears, complementing her polished appearance. The main focus is on her accessories with layered gold necklaces featuring small pendants and hoops earrings that match in tone. Her makeup is natural and refined, emphasising a smooth complexion, neutral lips, and well-groomed brows. The lighting is soft and even, highlighting her features with a gentle glow. The overall mood is poised, confident, and modern — fitting for a beauty, fashion, or jewellery editorial portrait.

A surreal cinematic scene set inside a vast, abandoned gothic cathedral with towering stone arches, cracked walls, and tall stained-glass windows diffusing cold, misty daylight. Suspended in mid-air at the center of the nave is a bright orange sports car, lifted by heavy chains and a metal hoist frame attached to the vaulted ceiling. The car hangs perfectly horizontal, emphasizing tension and impossibility. Moss, vines, and creeping vegetation reclaim the ancient stone interior, while puddles on the cracked stone floor reflect the cathedral’s architecture and the floating vehicle above. The contrast between the modern, glossy supercar and the decaying medieval environment creates a striking visual juxtaposition. Lighting is soft but dramatic, with volumetric light rays cutting through dust and fog, evoking a mood of mystery, surrealism, and post-apocalyptic elegance. Highly detailed, cinematic realism with a dark, contemplative atmosphere.

A striking close-up portrait of a vividly colored lizard perched on a textured rock, captured at eye level with shallow depth of field. The reptile features an extraordinary gradient of saturated hues—electric blue scales along the body, fiery orange and red tones on the head and limbs, and subtle purple transitions across the neck and torso. Fine scale textures are sharply detailed, with glossy highlights catching the light. One large, reflective eye is in crisp focus, conveying alertness and curiosity. The background fades into a dark, softly blurred gradient, isolating the subject and enhancing contrast. Lighting is dramatic yet controlled, emphasizing color vibrancy and surface detail. The overall mood is bold, exotic, and visually arresting, ideal for wildlife art, fantasy realism, or high-end digital illustration.

A close-up wildlife portrait of a majestic stag standing still in a snowy forest during active snowfall. The deer faces the camera directly, with large symmetrical antlers coated in fresh snow, creating a striking and powerful composition. Its fur is a rich warm brown, lightly dusted with snowflakes, contrasting against the soft white foreground and cool gray-blue background. The background features blurred winter trees with shallow depth of field, producing a dreamy, atmospheric bokeh effect. Lighting is soft and diffused, typical of overcast winter conditions, emphasizing fine details in the fur, antlers, and snow texture. The mood is calm, serene, and slightly dramatic, evoking wilderness, nature, and seasonal beauty. Shot at eye level with a centered composition, high realism, no text, ideal for commercial wildlife, winter, or holiday-themed stock imagery.

a person wearing a futuristic, minimalist outfit. They are dressed in a light gray or off-white high-collared jacket made of smooth, water-resistant material, featuring multiple zippers, pockets, and technical detailing. The jacket’s hood is pulled up, covering much of the head and framing the face symmetrically. The person is also wearing large, reflective black visor-style sunglasses, giving a high-tech, sci-fi, or avant-garde fashion aesthetic. The background is a clean, neutral gray-white, emphasizing the sleek design and monochrome palette of the outfit. The overall look is modern, stylish, and futuristic, blending elements of performance wear, fashion editorial, and sci-fi costume design — a perfect visual for a high-end techwear or minimalist fashion campaign.

This image shows a stylized humanoid robot with a golden metallic head, neck, and hands, dressed in a quirky combination of ornate gold armor plating and a knitted sweater in red and white. The robot is posed in front of a vintage beige computer, with its hands placed on the keyboard as if typing. The robot’s design mixes retro-futuristic and medieval elements: its golden body parts resemble old-fashioned robotics, while the armor-like plating on its shoulders and chest evokes a knightly aesthetic. The knitted sweater adds a humorous, almost domestic contrast to the otherwise mechanical and regal look. The background is a simple pink wall, which, along with the warm lighting, gives the scene a playful, staged, and slightly surreal vibe. The overall mood is whimsical, ironic, and imaginative, blending themes of technology, fashion, and retro nostalgia in a visually striking way.

Why teams choose FLUX Kontext Max

Choose FLUX Kontext Max when you have one image you like and need a targeted change described in words. It keeps the edit narrow, so the rest of the frame stays put. If the job needs several reference images at once, or output above its aspect-ratio presets, use FLUX 3 Image or Seedream 5 Pro instead, and always check product labels and logos after an edit.
