What it does
Seedream v4.5 Sequential, in practice.
Seedream 4.5 is a state-of-the-art, multimodal generative model engineered for scalability, efficiency, and professional-grade output. As an advanced version of Seedream 4.0, it is built upon a unified framework that seamlessly integrates text-to-image synthesis, sophisticated image editing, and complex multi-image composition. The model's primary design goal is to deliver professional visual creatives with exceptional consistency and fidelity. This is achieved through a significant scaling of the model architecture and training data, which enhances its ability to preserve reference details, render dense text and typography accurately, and understand nuanced user instructions.
- Unified Multimodal Framework: Integrates text-to-image (T2I), single-image editing, and multi-image composition into a single, cohesive model, allowing for diverse and flexible creative workflows.
- High-Fidelity & High-Resolution Generation: Capable of generating native high-resolution images (up to 4K), capturing fine details, realistic textures, and accurate lighting for professional use cases.
- Advanced Image Editing: Excels at preserving the core structure, lighting, and color tone of reference images while applying precise edits based on natural language instructions.
- Enhanced Multi-Image Composition: Accurately identifies and blends main subjects from multiple reference images, enabling complex creative compositions and style fusions.
- Superior Typography and Text Rendering: Features significantly improved capabilities for rendering clear, legible, and contextually integrated text within images.
- Efficient and Scalable Architecture: Built on a highly efficient Diffusion Transformer (DiT) and a powerful Variational Autoencoder (VAE), enabling fast inference and effective scalability.

Sample prompt
The prompt behind the sample.
Generate a sequence of 6 atmospheric city alley scenes that all take place in the same narrow street, with consistent architecture, signs, perspective and overall style. Style: realistic photography with a slight cinematic film look, soft grain, subtle lens bloom, inspired by Japanese backstreets. Scene 1 – Early Morning: the alley is quiet and almost empty, cool blue light, shutters half-closed, a faint mist on the ground. Scene 2 – Late Morning: shops are open, warmer sunlight enters the alley, a few people walking and bicycles parked, brighter colors. Scene 3 – Golden Hour: warm orange lig
