Pixel-space diffusion avoids this information loss, yet existing approaches map each raw image patch to a single token, forcing one representation to handle both global communication and fine-grained details. We address this issue by proposing a new architecture, \\textbf{DuSPiT}, a \\textbf{Du}al-branch \\textbf{S}ub\\textbf{P}atch \\textbf{Pi}xel \\textbf{T}ransformer. This model separates global structural reasoning from local appearance modeling. DuSPiT uses a compact base branch for efficient global reasoning and a parallel, high-capacity pixel branch, organized into subpatch groups, to preserve detailed appearance, with the two branches interacting through cross-attention. Our results show that DuSPiT generates images with richer details and stronger fine-grained structures, while also achieving a better quality--efficiency trade-off than prior pixel-space diffusion transformers.", "url": "https://wpnews.pro/news/duspit-dual-branch-sub-patch-pixel-diffusion-transformer", "canonical_source": "https://arxiv.org/abs/2607.18510", "published_at": "2026-07-22 04:00:00+00:00", "updated_at": "2026-07-22 04:13:42.989123+00:00", "lang": "en", "topics": ["artificial-intelligence", "machine-learning", "computer-vision", "generative-ai"], "entities": ["DuSPiT"], "alternates": {"html": "https://wpnews.pro/news/duspit-dual-branch-sub-patch-pixel-diffusion-transformer", "markdown": "https://wpnews.pro/news/duspit-dual-branch-sub-patch-pixel-diffusion-transformer.md", "text": "https://wpnews.pro/news/duspit-dual-branch-sub-patch-pixel-diffusion-transformer.txt", "jsonld": "https://wpnews.pro/news/duspit-dual-branch-sub-patch-pixel-diffusion-transformer.jsonld"}}
