Dreamina 3.1 is ByteDance's high-resolution image model with cinematic aesthetic defaults — atmospheric lighting, painterly composition, and strong material rendering at the 4 megapixel (2K) tier. It's the model to reach for when you want output that already looks edited.
Six aspect ratio presets (1:1, 16:9, 9:16, 4:3, 3:4, plus 'custom' for specific dimensions 256-2048px), two resolution tiers (1K for iteration, 2K for hero shots), and an optional prompt-enhance toggle. Pricing is flat across resolutions, so prefer 2K unless you specifically need 1K speed.
