Overview

About SeedDream 4

Seedream 4.0 is ByteDance's image model from September 2025. One model handles both text-to-image and image-guided work: give it a prompt alone, or add up to 10 input images to restage a product, swap a background, combine elements, or carry a style across a set. ByteDance positions it for speed, reporting about 1.8 seconds for a 2K image on its own infrastructure; in Masonry, time per image also depends on queueing and delivery.

In Masonry, Seedream 4 takes 10 preset sizes, from 2048 by 2048 square to a 3136 by 1344 ultra-wide frame, or an exact custom size up to 4K, such as 3840 by 2160. It takes a seed for repeatable results. Each request returns one image; Masonry runs more requests when you ask for several variations.

It suits fast concept rounds, product scenes built from your own photos, and variant sets for ads and listings. For the newer version with the same input limits, see Seedream 4.5; for the strongest in-image text, compare GPT Image 2 or Nano Banana Pro.

A serene lifestyle portrait of a woman seated cross-legged in a meditative lotus pose on a patterned woven rug inside a warm, thoughtfully decorated interior. She wears a soft pink sports bra and matching relaxed jogger pants, creating a harmonious monochrome look that reinforces calm and balance. Her posture is upright and grounded, shoulders relaxed, hands resting gently on her knees with palms open in a meditative mudra. Her eyes are closed, facial expression peaceful and centered, conveying mindfulness and inner stillness. Her natural curly hair frames her face loosely, adding softness and authenticity. She wears layered necklaces, including delicate chains and crystal pendants, along with a subtle choker, enhancing the spiritual, bohemian aesthetic. Tattoos on her arms add individuality and modern character. Surrounding her on the floor are carefully placed crystal formations—amethyst, quartz, and pastel-toned pyramids—arranged symmetrically to suggest energy balance and intentional ritual. Behind her, a wooden sideboard anchors the scene, topped with a small Buddha statue and decorative objects. The wall displays hanging crystal points and geodes in varying shapes and colors, reinforcing a holistic, wellness-focused environment. Potted plants and natural textures soften the space. Lighting is natural and diffused, likely from a nearby window, producing gentle shadows and a warm, inviting atmosphere. The color palette blends blush pinks, warm wood tones, muted purples, and soft neutrals. Shot at eye level with a centered, symmetrical composition, shallow depth of field, high realism, lifestyle wellness photography, no text, no logos, no branding.

A cinematic portrait of a woman astronaut standing on the rocky surface of a distant planet, beneath a pale sky tinted with faint atmospheric haze. The landscape stretches endlessly behind her — rugged terrain of sand, dust, and eroded stone, echoing the quiet desolation of alien worlds. She wears a futuristic evolution of a NASA-style spacesuit, sleek and advanced with matte white composite armor panels, metallic seams, and soft gold luminescent trims integrated into the fabric. The helmet’s clear visor reflects the horizon’s subtle glow, while translucent HUD graphics flicker faintly across its surface. Her expression is calm, determined, and introspective, capturing the weight of isolation and discovery. Fine dust drifts in the air around her boots, illuminated by soft, golden sunlight breaking through the thin atmosphere. The lighting is cinematic and naturalistic, blending warm highlights with cool blue shadow tones that create depth and emotional realism. In the distance, the outline of a futuristic landing craft gleams faintly, its lights shimmering through the dust — a silent reminder of humanity’s reach across the stars. The scene conveys a Gravity-meets-Interstellar tone: grounded realism infused with advanced design and quiet grandeur. Style: Futuristic cinematic realism, high-detail sci-fi portrait Lighting: Natural sunlight with soft atmospheric haze and rim glow Mood: Solitary, awe-inspiring, elegant, emotionally resonant Camera angle: Mid-frame eye-level portrait, shallow depth of field for dramatic focus

A steaming bowl of freshly prepared Maggi noodles with curly, golden-yellow strands glistening under warm ambient light. The noodles are lightly coated in a glossy, savory sauce with hints of spice, their texture appearing soft yet springy. Small bits of finely chopped vegetables — green chilies, onions, and tomatoes — add pops of color and freshness throughout. The dish is garnished with freshly chopped coriander leaves, a drizzle of soy sauce, and a few drops of chili oil for visual contrast. The bowl, rustic and ceramic with earthy tones, rests on a neatly folded beige linen napkin placed over a weathered wooden table, enhancing the homely, organic atmosphere. Wisps of steam rise gracefully from the noodles, subtly twisting upward into the air, suggesting heat and freshness. Around the bowl, scattered sprigs of herbs, a few slices of crusty bread, and a wooden spoon add authenticity and warmth. Soft, diffused lighting from the side casts gentle highlights on the noodles and delicate shadows on the table, evoking the golden glow of late afternoon. The overall mood is cozy, inviting, and nostalgic — a comforting homemade meal captured in perfect detail, ideal for illustrating home-cooked comfort food, Indian-style quick meals, or cozy kitchen moments.

Underneath, they wear a light blue dress shirt with the collar slightly open and a colorful striped tie worn loosely for a relaxed, modern look. The person accessorizes with dark sunglasses, black leather loafers, and a large textured black leather duffel bag held in one hand. Their wavy, shoulder-length dark hair and neutral expression add to the composed, fashion-forward aesthetic. The lighting is soft and even, emphasizing the outfit’s structure and texture, giving the overall scene a refined, editorial feel that blends classic menswear-inspired tailoring with contemporary minimalism.

a man outdoors in a cold, mountainous environment, dressed in technical winter gear. He is wearing a dark gray waterproof jacket with taped seams, multiple zippers, and orange accent details, giving it a sleek, high-performance look.

The jacket includes reinforced sleeves and pockets, and he is carrying a backpack with visible shoulder straps, suggesting he’s prepared for outdoor activity such as hiking or mountaineering.

The overall mood is elegant and contemporary, evoking themes of beauty, sophistication, and design harmony

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.
