What is Seedream 4.0?

Seedream 4.0 is ByteDance’s advanced AI image generation and editing model, designed to unify text-to-image creation and image editing within a single architecture. It offers rapid, high-resolution image generation with sophisticated understanding of complex prompts, making it suitable for both creative and professional applications.

It employs a highly efficient diffusion transformer and a powerful variational autoencoder (VAE) to rapidly generate high-resolution images ranging from 1K to 4K. Trained on billions of text-image pairs across diverse categories, Seedream 4.0 ensures stable, large-scale training with strong generalization capabilities. The system incorporates a fine-tuned vision-language model (VLM) for joint training of text-to-image and image editing tasks. For inference acceleration, it integrates techniques such as adversarial distillation, distribution matching, quantization, and speculative decoding, achieving inference times as low as 1.8 seconds for generating a 2K image.

What are the Key Features of Seedream 4.0?

Multi-Image Composition for Accelerated Creation: Supports multiple image inputs, enabling users to combine images with a single command. Batch output capabilities enhance the efficiency of the creative process.

Instruction-Based Editing for Results: Allows users to generate high-quality images and perform precise edits using simple language commands, achieving “what you see is what you get” results in image generation and editing.

Versatile Style Library for One-Click Stylization: Offers a professional style library, enabling users to apply various artistic styles—from watercolor to cyberpunk—to their images or personal photos, effortlessly creating unique visual languages.
