Seedream 4.5 is ByteDance's commercial-grade AI image generation model, ranked among the top 10 models globally on the LM Arena leaderboard. Engineered specifically for high-end commercial visual production, Seedream 4.5 excels where standard AI art models often struggle: accurate text rendering, photorealistic studio lighting, authentic material textures, and strict subject consistency across multiple variations.
Powered by an advanced Diffusion Transformer architecture with an integrated Cross-Image Consistency Module, Seedream 4.5 enables creators to upload up to 14 reference images simultaneously. This ensures that brand products, characters, and stylistic aesthetics remain perfectly consistent across e-commerce catalogs, marketing campaigns, and ad creatives. Whether you are generating native 4K product hero shots or editing existing photography using natural language prompts, Seedream 4.5 provides a dependable, production-ready visual studio.
Seedream 4.5 is calibrated for professional commercial photography. It accurately simulates complex optical effects, including glass caustics, metallic reflections, fabric textures, and subtle skin tones. You can easily control lighting conditions using professional photography cues like soft diffused studio light, golden hour, or dramatic rim lighting.
Overcome the frustrating gibberish of traditional AI image models. Seedream 4.5 renders crisp, highly legible English and Chinese typography directly onto product packaging, promotional posters, signage, and marketing cards, significantly reducing the need for manual graphic design touch-ups.
The specialized Cross-Image Consistency Module in Seedream 4.5 extracts and aligns identity-critical feature maps across up to 14 reference images. This allows you to generate complete product lines, character variations, and multi-angle catalog shots while maintaining unwavering brand and subject fidelity.
Generate crisp images at native resolutions up to 4096×4096 pixels without relying on third-party upscalers. Seedream 4.5 renders fine textures, micro-details, and clean edges that are ready for digital billboards, high-DPI web stores, and print media.
Combining text-to-image synthesis and image editing into a single, cohesive framework, Seedream 4.5 processes creative requests in 5 to 15 seconds. You can generate fresh ideas from scratch or perform targeted edits on existing images simply by describing what to alter and what to keep.
Write a descriptive prompt outlining your desired scene, subject, lighting, and typography. If you want to maintain product or character consistency, upload up to 14 reference photos (JPEG, PNG, or WebP formats, up to 10MB each).
Choose between Basic (2K) for swift mockups or High (4K) for maximum commercial detail. Select from popular aspect ratios including 1:1, 4:3, 3:4, 16:9, 9:16, 2:3, or 3:2.
