Features of Seedream 4.5

Production-Ready Visual Fidelity

Seedream 4.5 is engineered to generate images that meet professional standards right out of the gate. It produces photorealistic and stylistically coherent visuals with native 4K support, ensuring outputs are suitable for high-resolution commercial applications like advertising, product mockups, and digital content. The model excels at rendering intricate details, from textures and lighting to complex scenes, minimizing the need for extensive post-processing.

Perfect Text Rendering & Character Consistency

A standout technical achievement, this feature allows Seedream 4.5 to generate legible, correctly spelled text within images—a common failure point for other AI models. Furthermore, it maintains impeccable character consistency across multiple generated shots. This means a character's appearance, clothing, and style remain uniform in a series of images, which is crucial for storytelling, branding, and sequential visual projects.

Surgical Multi-Reference Image Editing

This advanced feature enables precise, "surgical" edits by allowing users to upload and reference up to 14 or more source images. You can guide the model to refine specific areas of an image—such as altering an outfit, changing a background element, or adjusting a style—while perfectly preserving the overall composition and aesthetic of the original. This provides an unparalleled level of control for iterative design and refinement.

Precise Instruction Following & Control

Seedream 4.5 demonstrates a superior capacity to understand and execute complex, detailed prompts. Users can provide extensive descriptive text (up to 6000 characters), specifying aspects like camera angles, lens effects, artistic styles, lighting conditions, and specific compositional elements. The model reliably interprets these nuanced instructions, translating detailed creative visions into accurate visual results.

Use Cases of Seedream 4.5

Commercial Advertising & Marketing

Marketing teams can rapidly generate high-quality, brand-consistent visual assets for campaigns, social media, and advertisements. The model's ability to render perfect text is ideal for creating promotional graphics with embedded slogans or logos, while its style consistency ensures a cohesive look across all campaign materials, from digital banners to print ads.

Concept Art & Storyboarding

Art directors, game developers, and filmmakers can use Seedream 4.5 to quickly visualize concepts and create detailed storyboards.

E-commerce businesses and designers can generate photorealistic product shots and lifestyle imagery without organizing costly photoshoots. The surgical editing feature allows for easy customization, such as placing a product in different settings or on various models, while maintaining perfect lighting and texture realism for a professional catalog.
