Seedream 4.0 vs Seedream 4.5
Detailed comparison of capabilities between the two Seedream AI image generation models. Choose the one that fits your creative and business needs.
| Feature Dimension | Seedream 4.0(ByteDance) | Seedream 4.5(ByteDance) |
|---|---|---|
| Core AI Model Architecture | ByteDance Seedream 4.0 — tuned for rapid generation and cost-effective creative prototyping. | ByteDance Seedream 4.5 — enhanced reasoning and real-world awareness for complex creative tasks. |
| Text-in-Image Rendering | Can generate text, but struggles with complex, multilingual, small-font, or ultra-clear requirements. | Significantly improved multilingual text with diverse fonts and crystal-clear rendering in generated images. |
| Resolution & Output Quality | Great for web and rapid creative work, limited 4K support. | Supports 2K and 4K output with advanced cinematic controls (lighting, depth of field, focus, camera angles). |
| Multi-Image Reference & Consistency | Good for prototyping but weaker for maintaining brand consistency across many assets or long character chains. | Accepts up to 14 references and keeps consistency across assets and multi-character scenes—ideal for brand/ads. |
| World Knowledge & Real-time Info | Primarily prompt-based with strong creativity but limited knowledge accuracy and data-driven visuals. | New search grounding improves visuals with real data, world knowledge, charts, maps, and technical workflows. |
| Creative Control & Editing | Basic generation/editing; limited detailed control (e.g., day-to-night) and multi-angle consistency. | Advanced controls: camera angles, focus changes, lighting shifts, color grading, aspect ratios—made for production. |
| Recommended Use Cases | Rapid ideation, social graphics, prototypes, drafts, viral images—cost/time friendly for high-volume experiments. | Brand ads, cross-language materials, high-res production visuals, omni-channel assets, charts, technical docs. |
| Speed & Cost Trade-offs | Faster, iteration-friendly—great for “generate volume, experiment more” workflows. | Heavier model with higher quality—slightly longer generation times and higher cost/quota per image. |
