About Seedream 4.5

Seedream 4.5 is ByteDance Seed's scaled-up revision of the Seedream 4 line, and this variant is its image editing mode. ByteDance's own framing of the 4.5 upgrade centers on editing: the model accurately identifies the main subjects in multi-image editing and strictly preserves the details of the reference images, holding facial features, lighting, and color tone steady while the requested change lands.

The editing mode is where 4.5 shows best on independent data. As of July 2026 it holds ByteDance's top score on the Artificial Analysis image-editing arena, slightly ahead of Seedream 4.0 and well ahead of Seedream 5.0 Lite. On Artifio it runs pay-per-generation alongside 100+ other models in one workspace.

Features

Instruction-driven editing of existing images, inherited from the 4.x unified generation-plus-editing architecture.
Multi-image editing that identifies the main subject across several references and applies the change to the right one.
Strict preservation of reference details: facial features, lighting, and color tone carry through the edit.
Enhanced typography and dense text rendering, so text replaced or added during an edit stays legible.
Controllable generation aimed at professional visual creatives needing consistency across a series of edits.

What people use it for

Swapping a product between photos while keeping the scene's lighting and perspective intact.
Keeping a person's face consistent across a set of edited scenes or campaign variants.
Replacing or restyling text inside an image, including dense small-print layouts.
Brand asset variations where color tone must stay locked to the original.

Reported strengths

Detail preservation in multi-image edits is the version's headline claim and the main measured gain over 4.0.
Best editing score in the Seedream family on the public Artificial Analysis arena: Elo 1184, rank 20, as of July 2026.
Typography quality carries into edits, which most editing models still fumble.

Reported limitations

It trails GPT Image 2, GPT Image 1.5, Nano Banana 2, and MAI-Image-2.5 on the Artificial Analysis image-editing arena, where the leader scores 1256 to its 1184 as of July 2026.
The margin over Seedream 4.0 on that public arena is a single Elo point; the larger improvement claims rest on ByteDance's internal MagicBench evaluation.
Public documentation is thin: no technical report or dedicated release post exists for 4.5, so specifics like maximum reference count are not stated for this version.
