Hello World
Inside a narrow antique bookstore in Prague, a woman in a wool coat runs her fingers across a shelf of leather-bound novels. Dust particles dance in the golden afternoon light filtering through stained-glass windows. The scene is quiet, textured, and intimate—camera glides over piles of books, ticking clocks, and her thoughtful gaze. It's as if time has slowed in a forgotten corner of the world.
A young man in a denim jacket and aviator shades leans on a vintage motorcycle at a desert gas station under a blazing sun. Heat waves ripple across the horizon, and an old jukebox plays classic rock through the open window of the diner. He lights a cigarette, looks into the distance—the camera captures the grit, texture, and restless spirit of retro Americana.
A couple drives a vintage convertible along a winding coastal road in southern France during golden hour. The wind tousles their hair, and the sea sparkles beside them. The camera captures them in soft, grainy light—sunlight flaring over the lens like old 35mm film. Their laughter mixes with the sound of the engine and seagulls. It’s cinematic, nostalgic, effortlessly romantic.
A backpacker in his twenties stands at a railway platform in Lisbon, gazing at an old graffiti-covered train as it pulls in. He wears headphones and carries a weathered map. The station is filled with soft natural light, pigeons fly past, and people blur around him. The atmosphere is meditative and sincere—a moment of transition and silent story.
A couple wrapped in a plaid blanket sits on a cliff overlooking the Atlantic Ocean under a sky scattered with stars. Waves crash below, and their silhouettes are outlined by moonlight. The camera slowly rotates around them as they point at constellations, wind tousling their hair. The motion is minimal yet deeply emotive—capturing intimacy, stillness, and wonder.
A girl in a soft white dress stands beneath a cherry blossom tree at twilight, her eyes closed as petals drift gently around her. The sky glows with hues of lavender and gold, and a slow breeze moves her hair and dress like silk. Her hand reaches out to catch a falling petal, and the camera lingers on the motion. The atmosphere is delicate, dreamlike, and filled with quiet longing—like a memory suspended in golden light.
A high-fashion editorial shot of a poised woman in avant-garde attire, standing confidently in a minimalist, architecturally designed interior. Clean lines, indirect lighting, and bold shadows create a striking contrast, emphasizing elegance and geometry.
A soft-lit, nostalgic portrait of a young woman seated beside a large window in a cozy vintage café, absorbed in thought. Light filters through sheer curtains, highlighting the warm tones of wooden furniture and the retro ambiance of the setting.
A dramatic fantasy scene of a fierce female warrior clad in intricately detailed silver armor, standing tall in a windswept golden field. Her sword gleams under the stormy sky, and her cloak billows in the wind, evoking the mood of a heroic epic.
A candid street-style photo of a teen boy wearing a slightly oversized retro windbreaker, hands in pockets, standing near a crosswalk. The city background is softly blurred, focusing attention on his pose and wardrobe, echoing urban fashion blogs.
A serene countryside portrait of a smiling girl sitting cross-legged in a lush green meadow dotted with daisies. The late afternoon sun wraps the scene in soft, warm light, and her simple dress billows slightly in the breeze.

FLUX.1 [dev]

Generate high-quality images with FLUX.1 [dev], a versatile and powerful image generation model. Whether you need text-to-image creation, image-to-image transformation, or precise inpainting — this model delivers stunning results with exceptional detail and prompt adherence.

Why It Stands Out

  • Multi-mode generation: Supports text-to-image, image-to-image, and inpainting workflows in one model.
  • High resolution output: Generate images up to 1024×1024 with sharp detail and clarity.
  • Prompt Enhancer: Built-in AI-powered prompt optimization for better results.
  • Flexible aspect ratios: Customize width and height independently for any format.
  • Batch generation: Create multiple images in a single request.
  • Reproducibility: Use the seed parameter to recreate exact results or explore variations.
  • Multiple output formats: Export as JPEG or PNG based on your needs.

Parameters

ParameterRequiredDescription
promptYesText description of the image you want to generate.
imageNoSource image for image-to-image or inpainting mode.
mask_imageNoMask image for inpainting (white areas will be regenerated).
strengthNoHow much to transform the source image (0.0–1.0, default: 0.8).
widthNoOutput width in pixels (default: 1024).
heightNoOutput height in pixels (default: 1024).
num_inference_stepsNoQuality/speed trade-off (default: 28).
seedNoSet for reproducibility; -1 for random.
guidance_scaleNoPrompt adherence strength (default: 3.5).
num_imagesNoNumber of images to generate (default: 1).
output_formatNoOutput format: jpeg or png (default: jpeg).
enable_base64_outputNoReturn base64 string instead of URL (API only).
enable_sync_modeNoWait for result before returning response (API only).

How to Use

Text-to-Image:

  1. Write a prompt describing the image you want. Use the Prompt Enhancer for AI-assisted optimization.
  2. Set width and height for your desired aspect ratio.
  3. Adjust guidance_scale and num_inference_steps as needed.
  4. Click Run and download your image.

Image-to-Image:

  1. Upload a source image.
  2. Write a prompt describing the transformation you want.
  3. Adjust the strength parameter — higher values allow more dramatic changes.
  4. Click Run and download your image.

Inpainting:

  1. Upload a source image and a mask image.
  2. White areas in the mask will be regenerated based on your prompt.
  3. Write a prompt describing what should appear in the masked region.
  4. Click Run and download your image.

Best Use Cases

  • Creative Art & Illustration — Generate unique artwork, concept art, and digital illustrations.
  • Product Visualization — Create product mockups and lifestyle imagery.
  • Marketing & Social Media — Produce eye-catching visuals for campaigns and posts.
  • Photo Editing & Enhancement — Transform or repair images with inpainting.
  • Design Prototyping — Quickly visualize ideas before committing to full production.

Pro Tips for Best Quality

  • Be descriptive in your prompt — include style, mood, lighting, composition, and specific details.
  • For image-to-image, use lower strength (0.3–0.5) to preserve more of the original, higher (0.7–0.9) for dramatic changes.
  • Use inpainting with precise masks for seamless object removal or replacement.
  • Fix the seed when iterating to compare the effect of different parameters.
  • Generate multiple images (num_images > 1) to explore variations quickly.

Notes

  • If using image URLs, ensure they are publicly accessible.
  • Processing time varies based on resolution and current queue load.
  • Please ensure your prompts comply with content guidelines.
