Seedream v4.5 vs FLUX.2 Max
Seedream 4.5 (ByteDance) and FLUX.2 Max (Black Forest Labs) frame a classic value-versus-fidelity decision in image generation. Seedream 4.5 is a fast, inexpensive workhorse with batch output and seed reproducibility. FLUX.2 Max is the maximum-fidelity tier built for hero assets. Both are hosted on Arteza with flat per-image pricing.

The bottom line
Use them as a pipeline rather than rivals. Seedream 4.5's low per-image cost makes broad exploration nearly free, and its seed control means the winning direction is reproducible. When the direction is locked, re-render the finalist on FLUX.2 Max for the fidelity pass. On Arteza this is a two-minute workflow because both share one studio and one credit balance.
Frequently asked questions
How big is the price difference?
Seedream 4.5 is one of the most affordable quality models hosted on Arteza, while FLUX.2 Max is a premium tier. The exact live credit cost for each is shown on this page.
What does seed reproducibility mean?
A seed is the random starting point of a generation. Fixing the seed on Seedream 4.5 lets you regenerate the same composition while tweaking the prompt, which makes iteration controlled instead of random.
Which produces larger images?
Seedream 4.5 outputs up to 2048x2048 (4 megapixels). FLUX.2 Max offers six size presets aimed at production use. Both lists are live in the image studio.
