When to Use Seedream 5 Lite

Seedream 5 Lite is the newer model with built-in reasoning capabilities. This means it understands context and intent behind your prompt, not just keywords.

Best use cases:

Complex multi-part prompts - "A kawaii cat wearing a kimono, holding a lantern, standing on a bridge over a koi pond at sunset" - Seedream 5 Lite understands spatial relationships better
Example-based editing - Upload a reference image and describe changes: "Same composition but make it winter with snow"
Character consistency - Upload multiple reference images of a character and generate new poses or scenes
Style transfer - Upload art style references and apply them to new compositions
Webtoon panels - Generate sequential scenes with consistent characters using multi-reference

Prompt tip:

Be descriptive and specific. Seedream 5 Lite's reasoning engine handles long, detailed prompts better than most models:

"A chibi anime girl with twin tails and star-shaped hair clips, sitting at a Japanese street food stall, eating takoyaki, cherry blossom petals floating, warm evening lighting, Studio Ghibli color palette"

When to Use Seedream 4.5

Seedream 4.5 is the established workhorse with 4K resolution support - the highest resolution available on SeniAI.

Best use cases:

Product photography - 4K output perfect for ecommerce listings, print catalogs, and large-format displays
Photoreal renders - Faces, architecture, food photography, and realistic scenes
Print-ready assets - Posters, banners, and marketing materials that need maximum resolution
Brand assets - Clean, professional visuals for corporate and commercial use
Custom dimensions - Supports custom width/height for non-standard aspect ratios

Prompt tip:

Seedream 4.5 responds well to photography-style prompts:

"Professional product photo of handmade ceramic tea cup, soft natural lighting, shallow depth of field, white marble surface, minimalist Japanese aesthetic, 4K quality"

Multi-Image Reference: How Both Models Excel

Both Seedream 5 Lite and 4.5 support uploading up to 14 reference images. This is a game-changer for:

Character sheets - Upload 3-5 views of a character, generate new scenes maintaining consistency
Brand guidelines - Upload your brand's visual assets as references for on-brand generation
Art style matching - Upload examples of your preferred style, generate new compositions in that style
Product variations - Upload a product photo, generate it in different colors, settings, or configurations
