What is Seedream 5 Lite?

Seedream 5 Lite is ByteDance's latest image generation model, the first to combine multi-step deep reasoning with real-time web search. It supports text-to-image and image-to-image modes at up to 3K resolution, with significantly improved prompt adherence and up to 10x faster generation than Seedream 4.5.

What makes Seedream 5 Lite different from Seedream 4.5?

Seedream 5 Lite adds three major capabilities absent in 4.5: real-time web search for factually grounded images, multi-step deep reasoning for complex scene understanding, and conversational (intent-based) editing that doesn't require precise commands. Generation speed is also up to 10x faster.

How does the web search feature work?

Seedream 5 Lite connects to the internet during image generation. When your prompt mentions trending topics, recent events, or new products, it retrieves current information to ensure the generated image is factually accurate and visually up to date—without any extra effort from you.

What resolutions are supported?

Basic quality generates 2K images for fast, cost-effective production. High quality generates 3K images (up to 3072×3072 pixels) for professional-grade output suitable for print and large displays.

How does Image-to-Image editing work?

Upload one or more reference images and describe your desired transformation in natural language. Seedream 5 Lite infers your intent—applying style transfer, relighting, recoloring, or compositional changes—while preserving the original image's core structure and identity.

What aspect ratios are available?

Eight aspect ratios are supported: 1:1, 4:3, 3:4, 16:9, 9:16, 2:3, 3:2, and 21:9—covering square, portrait, landscape, and ultra-wide formats for every platform and format requirement.

What's the maximum prompt length?

Text-to-Image supports prompts up to 2995 characters. Image-to-Image supports prompts up to 2996 characters—both allow detailed, nuanced descriptions for precise results.

Can I use the images commercially?

Yes. All images generated with Seedream 5 Lite are yours to use commercially in campaigns, products, websites, social media, and client projects without restrictions.
