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.

Choose Seedream v4.5 when

- You need reproducibility: seed control lets you revisit and refine a specific result.
- Multi-image batches per prompt to scan a wider creative space quickly.
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.
