About Seedream 4.5
Seedream 4.5 is ByteDance's mid-generation Seedream release, positioned between the 4.0 baseline and the newer 5.0 tier. It generates and edits images at 2K and 4K resolution, and accepts up to 14 reference images in a single request — reference images and any sequential outputs together cap at 15 per request. Multi-image composition holds up across busy layouts, reference detail carries through into the output, and small in-image text stays legible — useful for posters, packaging, and editorial layouts with real typography in frame.
