DeltaControl is made by finetuning a selected subset of layers in an existing text-to-image diffusion model rather than adding extra conditional branches, which the authors say lets it match dual-branch approaches such as ControlNet while remaining distillation-friendly. Step-distillation of DeltaControl then yields FlashControl, which produces spatially controlled images in a single forward pass instead of many sampling steps.", "body_md": "arXiv:2610.22537v1 Announce Type: new \nAbstract: Diffusion models have become a leading approach in visual generative modeling, particularly effective in text-to-image and controllable generation. Their main drawback is slow inference as it requires many sampling steps. While recent distillation methods enable one-step text-to-image generation, extending these techniques to controllable generation is still challenging. Existing controllable models, such as ControlNet, rely on dual-branch design that make distillation difficult. In this work, we adopt a simpler strategy. Instead of adding extra conditional branches, we finetune a selected subset of layers in the original text-to-image diffusion model to directly enable controllable generation. This results in DeltaControl, a single-flow, multi-step diffusion model capable of supporting spatial-condition generation while matching the performance of dual-branch approaches. Building on this teacher model, we further apply step-distillation to obtain FlashControl, a one-step model capable of spatial controllable generation with a single forward pass.", "url": "https://wpnews.pro/news/flashcontrol-one-step-controllable-generator-via-distillation-friendly-single", "canonical_source": "https://arxiv.org/abs/2610.22537", "published_at": "2026-10-19 04:00:00+00:00", "updated_at": "2026-10-19 04:21:47.483515+00:00", "lang": "en", "topics": ["generative-ai", "computer-vision", "ai-research", "machine-learning"], "entities": ["FlashControl", "DeltaControl", "ControlNet", "arXiv"], "also_reported_by": [], "alternates": {"html": "https://wpnews.pro/news/flashcontrol-one-step-controllable-generator-via-distillation-friendly-single", "markdown": "https://wpnews.pro/news/flashcontrol-one-step-controllable-generator-via-distillation-friendly-single.md", "text": "https://wpnews.pro/news/flashcontrol-one-step-controllable-generator-via-distillation-friendly-single.txt", "jsonld": "https://wpnews.pro/news/flashcontrol-one-step-controllable-generator-via-distillation-friendly-single.jsonld"}}
