What's new in Seedream 4.5?
Seedream 4.5 improves on version 4.0 with better detail consistency, photorealistic lighting, clean text rendering, and more accurate prompt interpretation. These upgrades focus on production reliability so images look professional without post-processing.
Detail Consistency
Multi-image generation maintains consistent details across faces, objects, and scenes without drift. Generate a character in multiple poses or environments and they'll look like the same person.
Light & Shadow
Realistic 3D depth with natural lighting. Product shots look photographed, not generated. Soft shadows, specular highlights, and ambient occlusion all behave correctly.
Text Rendering
Clean, readable text in images. Posters, product labels, and UI mockups no longer break with garbled typography. Small text renders legibly with proper kerning.
Prompt Control
Complex prompts with positioning, style constraints, and multi-part instructions interpreted accurately. Specify element placement and get what you asked for.
What can you create with Seedream 4.5?
Seedream 4.5 is used for e-commerce product images, marketing visuals, film pre-production, game art, educational diagrams, and architectural visualizations. Its strength is consistency. Characters and products look the same across multiple generated images.
E-commerce
Product image generation with consistent item details and color tones. Create lifestyle shots while preserving product accuracy.
Marketing & Ads
Ad-ready visuals with commercial-grade polish. Generate campaign variations at scale without losing brand consistency.
Film Pre-production
Scene generation, character visualization, and storyboard frames. Iterate on visual direction before committing to production.
Game Art
Character design, scene construction, and prop concepts. Maintain visual coherence across asset libraries.
Educational Content
Diagrams, historical reconstructions, and scientific visualizations. Knowledge-based imagery with accurate rendering.
Architecture
Layout renderings and style explorations. Rapid concept visualization for client presentations.
What's the difference between Seedream 4.0 and 4.5?
Seedream 4.5 upgrades detail consistency from "good" to "excellent," improves text rendering from basic to clean and readable, and adds photorealistic lighting. Version 4.5 also offers full support for complex prompts and browser-based access through Floyo.
What are Seedream 4.5's capabilities?
Seedream 4.5 supports text-to-image generation, image-to-image transformation, multi-image reference (up to 14 images), batch generation (up to 15 images), flexible aspect ratios from 1:16 to 16:1, and multiple output formats including JPEG, PNG, and WEBP.
Text-to-Image
Generate images from detailed text descriptions with complex scene composition. Output from 1K to 4K resolution.
Image-to-Image
Transform existing images with text instructions. Change backgrounds, modify objects, adjust lighting.
Multi-Image Reference
Upload up to 14 reference images to guide generation. Maintain character or brand consistency.
Batch Generation
Generate up to 15 images per prompt. Create variations or produce asset sets efficiently.
Flexible Ratios
Support for aspect ratios from 1:16 to 16:1. Optimized for any platform or format.
Format Support
Input and output for JPEG, PNG, WEBP, BMP, TIFF, and GIF formats.
What are Seedream 4.5's technical specifications?
Seedream 4.5 generates images up to 4K resolution (16.7 megapixels), supports aspect ratios from 1:16 to 16:1, accepts up to 14 reference images, and can batch generate up to 15 images per prompt. It runs in-browser on Floyo with no local installation required.
How does Seedream 4.5 work?
Seedream 4.5 uses a unified AI architecture that combines text-to-image generation and image editing in one system. It processes text prompts and optional reference images to generate new visuals, handling tasks like compositional reasoning, knowledge-based generation, and multi-image consistency.
The model was trained by ByteDance to focus on production reliability. Detail consistency across multi-image generation has been significantly improved. Faces, objects, and scene elements maintain coherence without the drift that plagued earlier versions. Light and shadow processing creates more convincing 3D depth, giving product shots a photographed quality.
Text rendering sees major improvements. Small text in posters, product labels, and designs now renders cleanly and legibly. This addresses one of the most common complaints with AI image generation: garbled typography.
Prompt interpretation is more accurate for complex instructions. Multi-part prompts with specific positioning requirements, style constraints, and compositional details are handled reliably.
