SD 3.5 Large — implementation by Spacelike AI
Multimodal Diffusion Transformer · 8.1 B parameters · Stability AI
SD 3.5 Large is the flagship of the SD 3.5 family. At 8.1 B parameters it is the largest MM-DiT-based Stable Diffusion model Stability AI has released, targeting professional image generation at 1-megapixel native resolution with substantially improved typography, anatomy and compositional coherence over SD 3.
A sibling distilled variant, SD 3.5 Large Turbo, produces equivalent quality in 4 steps at the cost of some prompt adherence. Both share the same MM-DiT backbone.
