image-to-image

[Core Function] Seedream 5.0 Lite Edit is a reasoning-enhanced, smart image editing model. [Strengths] It features superior cross-modal understanding and reasoning, allowing for highly accurate, interactive multi-turn image editing with real-time knowledge enhancement. [Best For] Highly recommended for: complex image editing tasks, structural modifications, and edits requiring deep semantic understanding. [Limitations] As a 'Lite' model, raw visual rendering might not match the 4.5 tier. [Routing] Use this model by default for complex, reasoning-based image editing tasks.

text-to-image

[Core Function] Seedream 5.0 Lite is a smart, reasoning-enhanced image generation model with real-time web search capabilities. [Strengths] It excels at generating time-sensitive imagery, infographics, and content requiring deep world knowledge or online search, boasting superior prompt understanding and reasoning. [Best For] Highly recommended for: current-event posters, text-heavy designs, and concept art requiring complex logical reasoning. [Limitations] As a 'Lite' model, its absolute photorealistic aesthetic ceiling might be slightly lower than the specialized 4.5 model. [Routing] Use this model by default when the user needs real-time information, deep reasoning, or complex intent understanding in their image.

image-to-image

[Core Function] Seedream 4.0 I2I is an older generation image-to-image editing model. [Strengths] Maintained primarily for backward compatibility and stable API contracts. [Best For] Existing legacy integrations and workflows that strictly depend on this specific model version's quirks. [Limitations] Do NOT use this for new creations. It is a legacy model maintained for backward compatibility. [Routing] Only use if explicitly requested; otherwise use Seedream 5.0 Lite I2I.

image-to-image

[Core Function] Seedream 4.5 I2I is a high-fidelity image editing model. [Strengths] It provides high-consistency, high-resolution style transfer and image-to-image transformations. [Best For] Highly recommended for: professional aesthetic modifications and high-resolution edits. [Limitations] Lacks the advanced reasoning of 5.0 Lite. [Routing] Use this for pure aesthetic/high-fidelity edits.

text-to-image

[Core Function] Seedream 4.0 T2I is an older high-definition image creation model. [Strengths] It generates high-definition images up to 4K. [Best For] Existing workflows. [Limitations] Superseded by Seedream 4.5 in fidelity and consistency. [Routing] Default to Seedream 4.5 unless 4.0 is explicitly requested.

text-to-image

[Core Function] Seedream 4.5 T2I is a high-fidelity visual creation model. [Strengths] It provides all-round improvements in consistency, aesthetics, and photorealism, supporting high-definition outputs up to 4K resolution. [Best For] Highly recommended for: professional visual creatives, photorealistic artwork, and high-res commercial graphics. [Limitations] It lacks the real-time web search and advanced reasoning capabilities of the 5.0 Lite model. [Routing] Use this model when the priority is absolute visual fidelity, resolution (4K), and consistency without the need for real-time search.
