Hildegard generates reference latents for each tile, including its neighbors and a thumbnail of the entire image, to improve context understanding and prevent seams or hallucinations. AI

IMPACT Provides enhanced contextual upscaling for Stable Diffusion workflows, improving image quality and reducing artifacts.
