Introduction

Seedream 4.0 is one of the latest ByteDance's AI image models, delivering 4K-resolution outputs with impressive clarity and detail. It combines photorealism and multi-reference editing with faster performance and improved consistency across outputs.

This model is now fully available inside Freepik, so you can explore its capabilities directly in the AI Suite. In this guide, you’ll find everything you need to know about Seedream 4: its key features, how to use it step by step in Freepik, prompting tips, and the best use cases.

What is Seedream 4.0?

Seedream 4.0 is a text-to-image and image editing AI model developed by ByteDance, the Chinese tech giant behind TikTok and Douyin. It is part of the company's SEED AI research program and follows the release of Seedream 3.0, which set a benchmark in high-resolution image generation and accurate typography.

Unlike its predecessor, Seedream 4 is better suited for both text-to-image tasks and image editing with references. It has been developed as a direct competitor to Google Nano Banana, offering similar strengths such as multi-reference editing, one-shot accuracy, and improved consistency.

Key features of Seedream 4.0

Seedream 4.0 is ByteDance's most advanced multimodal text-to-image and image-editing model. It builds on the strengths of Seedream 3.0 but introduces several improvements that make it more powerful, flexible, and production-ready:

• Multi-image editing with up to 6 references

  Seedream 3.0 allowed 4 reference images, while Seedream 4.0 extends this to 6, enabling richer compositions that combine multiple products, characters, or backgrounds in one generation.

• Native 4K resolution support

  While Seedream 3.0 was limited to 2K, Seedream 4.0 generates outputs natively at 2K and 4K, making it suitable for print, large-scale campaigns, and high-end commercial work.

• Improved one-shot accuracy

  Complex edits that previously required retries in Seedream 3.0 can now be achieved in a single attempt, streamlining workflows and saving credits.

• Better consistency across outputs

  Character identity, product appearance, and lighting are maintained more reliably across variations and batch generations than in Seedream 3.0.

• Advanced typography rendering

  Seedream 3.0 introduced sharp English and Chinese text. Seedream 4.0 expands this with multilingual typography handling and improved placement for layouts like posters or ads.

• Faster generation speed

  Thanks to optimized inference, Seedream 4.0 is noticeably faster, generating 4K visuals in near real time.

• Full integration with Freepik

  As with Seedream 3.0, this new version is available directly inside the Freepik AI Image Generator and Image Editor, but with additional improvements for multi-reference workflows and editing precision.

Limitations and weaknesses

Even with these upgrades, Seedream 4.0 still has constraints to be aware of:

• No native video generation: Like Seedream 3.0, it focuses on image creation and editing. Video tasks still rely on models like Seedance or Kling.
• Stylized or abstract prompts may need refinement: While accuracy has improved, highly experimental or surreal prompts may still require iteration.
• Resource-heavy at 4K: Although faster than before, generating at 4K consumes more credits and system resources.
• Preview release: As a new model, some features are still being tested and may evolve over time
