Seedream 4.5
by ByteDance
The cheapest way to a 2K image in Canvas — and it looks photoreal.
Seedream 4.5 is ByteDance's image model tuned for photorealism at a low cost. It outputs 2K images natively and 4K at twice the price, handles product photography and lifestyle scenes convincingly, and takes reference images so a real product carries into the render.
It is the workhorse for volume: catalogue-style shots, lifestyle scenes for a range of products, and quick variations for ad testing where a 2K image is all the channel needs.
