Features

Platform philosophy

Precision and flexibility: Seedream puts control in your hands—choose exactly the aspect ratio and resolution you need, from social squares to ultra-wide cinematics. High-quality output at 2K or 3K ensures your visuals stand out, whether for web, print, or digital campaigns.

Simplicity without compromise: With straightforward parameters and generous prompt limits, Seedream balances ease of use with professional-grade results. It's built for creators who demand both creative freedom and technical reliability.

Core capabilities

5 Lite Text to Image

Describe your vision in detail—up to 2995 characters.

Select aspect ratio: 1:1, 4:3, 3:4, 16:9, 9:16, 2:3, 3:2, 21:9.

Choose quality: Basic 2K (fast, efficient) or High 3K (enhanced detail and clarity).

Ideal for concept art, stickers, social posts, and rapid visual exploration.

5 Lite Image to Image

Upload one or more images (JPEG, PNG, WebP; max 10MB each).

Add a text instruction (e.g., "change lighting to golden hour," "convert to sticker style," "transfer this style to the subject").

Apply the same aspect ratio and quality controls as text-to-image.

Perfect for style unification, lighting adjustments, detail polishing, and creative remixing.

Use cases

Sticker creation: Generate custom stickers with precise control over style and format.

Lighting edits: Transform the mood of an image by changing lighting conditions via text prompts.

Style transfer: Apply artistic or brand styles consistently across multiple assets.

Marketing assets: Produce social media graphics, banners, and ads with tailored aspect ratios.

Concept iteration: Rapidly explore variations of a design by tweaking prompts and parameters.

Educational content: Create visuals for presentations, blogs, and student projects with high-quality output.

Technical performance

Text-to-image generation: Typically completes in 10–25 seconds for Basic 2K, 20–40 seconds for High 3K (dependent on complexity).

Image-to-image generation: 15–30 seconds for most edits; supports batch processing for multiple images.

Concurrency: Handles 50+ parallel requests smoothly.

Input formats: JPEG, PNG, WebP (max 10MB per image).

Prompt length: Up to 2995–2996 characters, enabling rich, detailed descriptions.

Workflow

Quick create: Write a detailed prompt → select aspect ratio and quality → generate → review and refine.

Batch editing: Upload a set of images → apply the same style or lighting instruction → unify output with consistent settings.

Team collaboration: Share generated assets in real time, collect feedback, and iterate quickly using version tracking on FuseAITools.

Optimization tips

Prompt crafting: Be specific: [Subject] + [Action/Scene] + [Style/Lighting] + [Key details]. For image-to-image, clearly state what to change (e.g., "make it sunset lighting" rather than just "change lighting").

Resolution strategy: Use Basic 2K for drafts and internal reviews; switch to High 3K for final assets.

Batch efficiency: Group similar tasks (e.g., same aspect ratio/style) to minimize reconfiguration.

Cost management: Optimize by reusing successful prompts and caching frequently used instructions.

Quality control: Experiment with different prompts and aspect ratios to find the best combination; iterate from Basic to High for polish.

Platform advantages
