TikTok Parent ByteDance Takes on DeepMind with Seedream 4.0

TikTok’s parent company ByteDance has unveiled Seedream 4.0, its latest image generation AI model, bringing advanced editing and design capabilities to users. Positioned as a direct competitor to Google DeepMind’s Nano Banana (Gemini 2.5 Flash Image), the new tool emphasizes accuracy, creativity, and aesthetic quality in AI-generated visuals. Backed by the company’s AI research arm, Seed Department, Seedream 4.0 represents ByteDance’s bold step in challenging Google in the fast-growing AI image generation market.

Seedream 4.0 vs. Google DeepMind’s Nano Banana

ByteDance has openly positioned Seedream 4.0 against Nano Banana, a flagship model from Google DeepMind. According to the company, Seedream 4.0 scored higher on MagicBench, an internal evaluation benchmark for image generation and editing. The model reportedly outperformed Nano Banana in three critical areas:

• Prompt adherence – accurately following user instructions.

• Alignment – producing content aligned with input requirements.

• Aesthetics – generating visually appealing and high-quality images.

This comparison highlights ByteDance’s ambition to not only catch up with but surpass Google in the field of creative AI tools.

Key Features of Seedream 4.0

1. Advanced Image Editing

Seedream 4.0 enables users to perform a wide range of image edits, such as adding, deleting, replacing, or modifying elements through text prompts. By using clear and concise language, users can specify details precisely, ensuring better accuracy in edits. This makes the tool highly useful for designers, marketers, and casual users alike.

2. Reference-Based Image Generation

One of the standout features is its ability to extract key details from reference images. This includes aspects such as:

• Character design

• Artistic style

• Product features

With this functionality, Seedream 4.0 can be used for character creation, product design, and style transfers, allowing creators to replicate styles or merge visual elements seamlessly.

3. Multi-Image Input Support

Unlike many AI models that rely on single prompts or single reference images, Seedream 4.0 supports multi-image inputs. This feature enables composite editing, where elements from different images can be combined or replaced to form a new creation. It is especially useful for professional tasks such as advertising campaigns, fashion design, and product visualization.

4. Image Sequences with Continuity

Seedream 4.0 can generate image sequences with consistent character continuity and a unified style. This feature is particularly beneficial for:

• Storyboarding for films and videos

• Comic and manga creation

• Set-based design scenarios

• IP product and emoji pack development

By maintaining a cohesive visual identity across multiple frames, Seedream 4.0 gives creators the ability to produce professional-grade content efficiently.

Seedream 4.0 Prompt Guide for Better Results

ByteDance has shared guidelines to help users craft effective prompts and maximize the potential of Seedream 4.0:

• Use natural language clearly: Describe the subject, action, and environment in detail. For artistic quality, include descriptors like style, color, lighting, or composition.

• Specify the application scenario: Clearly state the purpose of the image—whether it is for marketing, product design, or creative storytelling.

• Enhance style with precision: Include specific style keywords or attach reference images to achieve desired visual effects.

• Improve text rendering: For text within images, enclose words in double quotation marks to improve accuracy.

These guidelines ensure that users can get precise, aesthetic, and contextually accurate results from the model.

Why Seedream 4.0 Matters in the AI Race

With Seedream 4.0, ByteDance has signaled its entry into the global AI race, directly competing with industry giants like Google DeepMind and OpenAI. While Google’s Nano Banana has already gained attention, ByteDance’s claim of outperforming it in benchmarks gives Seedream 4.0 a competitive edge.

The AI image generation market is booming, with applications across digital marketing, entertainment, design, e-commerce, and social media content creation. By leveraging TikTok’s massive user base and integrating Seedream 4.0 into creative workflows, ByteDance could gain significant ground in the creative AI ecosystem.

Conclusion

ByteDance’s Seedream 4.0 is more than just an AI image generation tool—it’s a statement of intent in the global AI rivalry. With cutting-edge editing features, reference-based design, multi-image input, and sequence generation, the model caters to both professionals and everyday creators.

As the AI competition between ByteDance and Google DeepMind heats up, Seedream 4.0 has the potential to redefine digital creativity, making AI-driven design more accurate, accessible, and versatile.
