Seedream 4.5AI image generator
Previous Seedream, up to 4K. Pay only for the takes you keep — kill the rest for a full refund.

Seedream 4.5 is ByteDance's image model, released December 2025 as a refinement of Seedream 4.0. It is known for edits that keep the subject, lighting, and color intact, sharper small text and poster typography, clearer faces even when the subject is small in frame, and output up to 4K. On Elyum it is text to image and image editing, with five aspect ratios.
Use it when a poster, product still, or catalog set has to keep the subject and the type readable — campaign variations, packaging comps, and edits on an approved frame. One credit balance across 50+ models, from a Free plan with 150 starter credits up to Ultra, plus top-ups. Also runs from Claude, ChatGPT, and Cursor through Elyum's MCP server and REST API.

Why Seedream 4.5 is good
ByteDance built 4.5 to hold the reference: face, lighting, and color stay put while you change wardrobe, background, or copy. That is the main step up from Seedream 4.0.
ByteDance highlights sharper small-text and poster typography. Headlines, labels, and dense layout copy stay readable instead of melting into the frame.
Face rendering improved versus 4.0, including when the person occupies a small part of the frame. Useful for group shots, lifestyle stills, and wide catalog crops.
