As an upgraded Seedream AI model, it supports multimodal capabilities including text-to-image creation, image-to-image editing, and group image generation, giving users unmatched creative flexibility. One of its standout strengths is speed and quality—producing a 2K-resolution image in as little as 1.8 seconds and scaling up to ultra-detailed 4K visuals.

Key highlight features of ByteDance Seedream 4.0

ByteDance Seedream 4.0 introduces five standout advancements that make it one of the most powerful AI image-generation models available today. These features combine precision, speed, and flexibility, helping creators across design, art, and entertainment unlock new creative potential.

1
1. Smarter instruction editing

With Seedream 4.0, you don't need complicated workflows—just describe what you want in plain language, and the AI makes it happen. Whether you ask it to add, delete, replace, or modify elements, the model responds with uncanny accuracy.

For example, in the image above, the original snowy street outside the restaurant window was instantly replaced with a dramatic explosion scene, while every other detail—the girl, her pasta, the wine glass, and candlelight—remained untouched. This level of precise editing opens endless possibilities for commercial design, artistic storytelling, and playful entertainment.

Sample prompt: Replace the snowy street outside the window with a massive explosion, keeping the girl, food, and interior lighting unchanged.

1. High-fidelity feature preservation

Seedream 4.0 ensures that your edits never come at the cost of losing detail. Its character retention keeps subjects consistent across creative formats, whether you're working with photography, 3D renders, or illustration. A corgi photographed from different angles, for example, will always maintain its distinctive features, no matter how the scene changes.

Sample prompt: Zoom into the corgi lying on the grass while keeping its facial details and fur texture sharp and natural.

It also excels at picture retention, keeping textures crisp and natural. Say goodbye to the “AI greasy look”—Seedream 4.0 maximizes original details so every edit feels smooth, sharp, and true to life. Whether you're transferring an illustration onto a product mockup or refining a photo, the integrity of the source remains intact.

Sample prompt: Place this illustrated character design onto a white canvas bag mockup while retaining its original colors and style.

1. Deep intent understanding

Seedream 4.0 doesn't just follow instructions; it truly grasps your intent. This feature allows the model to interpret vague or complex prompts and deliver results that feel like they came from a creative partner rather than a machine.

Knowledge upgrade: With expert-level understanding, Seedream 4.0 can handle technical concepts or nuanced descriptions with precision, turning a rough sketch into a detailed blueprint.

Sample prompt: Transform this rough sketch of a delivery robot into a detailed 3D-style concept sheet with color, annotations, and multiple angles.

From inspiration to reality: Even abstract prompts or quick sketches can evolve into polished, high-quality visuals, bridging the gap between imagination and execution.

Sample prompt: Convert these fencing practice sketches into lifelike 3D figures posed dynamically as if on display models.

Reasoning and prediction: The AI can simulate beyond the present — imagining movement, progression, or changes in environment, giving depth and context to visuals.

Sample prompt: Generate a high-resolution photo of a woman sitting inside a square frame, using the depth map as reference for pose and proportions.

Adaptive scaling: Automatically matches the best proportions and aspect ratios for your content, so your designs look professional without extra editing.

Sample prompt: Turn this simple product shot of an apple into a modern advertising poster with a tagline and brand logo on a clean gradient background.

1. Multi-picture input and output

Seedream 4.0 isn't limited to single-image tasks—it thrives on working with multiple sources at once. With multi-image input, you can upload several references together and let the model combine, swap, or evolve them into a unified composition. This is perfect for high-level edits like merging characters from different photos, applying a sketch to real-world styles, or evolving concepts into finished designs.

Sample prompt: Combine these two reference portraits of ancient characters into a modern photo where they take a selfie together.

On the other side, multi-picture output lets you generate entire sets of related images in one go. Whether you're creating a storyboard, comic sequence, or product variations, the model ensures visual consistency across every frame. This transforms brainstorming into production-ready storytelling.

Sample prompt: Using these two character portraits as references, generate a connected comic book sequence of them in different action scenes, maintaining their unique features and consistent art style.

Use cases for Seedream 4.0

Commercial design

Seedream 4.0 is a powerful tool for commercial design, making it easy to create professional visuals for posters, packaging, logos, and e-commerce product images. It allows designers to mix references, apply branding consistently, and visualize products in real-world contexts. By combining multiple inputs, businesses can quickly generate polished marketing assets that look ready for campaign launches.

Sample prompt: Dress the model in Figure 3 with the black Adidas t-shirt from Figure 1, the shorts from Figure 2, and the sandals from Figure 4. Generate a realistic e-commerce photo with a studio background.

Art & storytelling

Seedream 4.0 makes it effortless to bring stories to life through comic panels, film storyboards, illustrations, and even sketch coloring. Creators can use simple prompts or rough outlines to generate full narrative sequences with consistent characters and styles. This makes it a powerful tool for writers, artists, and filmmakers who want to visualize ideas quickly, explore different scenarios, and refine storytelling without needing manual drawing.

Sample prompt: Create a 4-panel comic storyboard of a young boy in a yellow hat and orange shirt traveling. Panel 1: he takes a selfie in the city. Panel 2: he waits at the airport. Panel 3: he looks out the airplane window at the clouds. Panel 4: he arrives at school, walking under purple blossoms.

Entertainment & play

Seedream 4.0 isn't just for professionals—it also fuels fun and creativity. From portraits and style transfers to face swaps, emojis, and memes, the model helps users transform everyday photos into something playful or artistic. Whether you want to reimagine yourself in a different style, swap characters in a scene, or create viral meme-worthy edits, Seedream makes it fast and effortless while keeping details sharp and realistic.

Sample prompt: Take the portraits of the woman and man and generate a romantic candlelit scene where they are posing together in a dramatic, cinematic style. Keep their facial details consistent.

Creative face swapping

Seedream 4.0 allows creators to swap faces seamlessly, transforming classic art or portraits into playful, imaginative variations. In the example above, the famous Girl with a Pearl Earring painting has been reimagined with a cat and a fox while retaining the original style, colors, and details. This makes it a powerful tool for meme creation, art reinterpretation, and entertainment projects where you want to add humor or unique twists to existing visuals.

Sample prompt: Recreate Johannes Vermeer's Girl with a Pearl Earring painting, but replace the girl's face with a realistic cat's face, maintaining the same lighting, clothing, and painterly style. Generate an alternate version with a fox's face while keeping the artistic consistency of the original artwork.

Personification in creative design

Seedream 4.0's personification feature allows creators to bring life and emotion into inanimate objects, turning simple icons or items into relatable characters. For example, transforming a playful emoji into a cartoon-like car with the same facial expressions creates engaging visuals for children's books, educational apps, marketing campaigns, or playful brand mascots. This is especially useful in storytelling and entertainment, where objects need personality to connect with audiences.

Sample prompt: Transform a playful winking emoji with tongue out into a cheerful yellow cartoon car. Keep the car's headlights styled like eyes, add the same wink expression, and place a tongue sticking out as if the car is mimicking the emoji. Maintain a bright, friendly, cartoon style suitable for kids' media or branding.

Now, ByteDance's Seedream 4.0 has arrived—with promises of combining high-resolution output, precise editing, and prompt fidelity in ways that challenge both giants.
