LCM DreamShaper v7 (0.86B parameters) requires approximately 5.9 GB of VRAM at FP16 precision for standard 1024×1024 image generation. If you want a lighter setup, lower precisions like FP8 can reduce memory use when available.
LCM DreamShaper v7 usually needs more than 8GB for comfortable local use. Check the VRAM table above for the exact resolution and precision trade-off.
LCM DreamShaper v7 is marked for ComfyUI and Diffusers support in our catalog, so those are the runtimes we recommend first for local setup. If your workflow uses another front end, check the model's available formats and workflow notes above before downloading.
Yes, the RTX 4090 (24 GB VRAM) can run LCM DreamShaper v7 comfortably at FP16. Expected generation time is around 300ms per image at 1024×1024.
Yes, LCM DreamShaper v7 has 2 ControlNet adapters available: Canny Edge (SD 1.5), Depth Map (SD 1.5). Each ControlNet adds roughly 0.7 GB of extra VRAM.
Inherits full SD 1.5 LoRA ecosystem — 50,000+ LoRAs on CivitAI. The LoRA ecosystem for LCM DreamShaper v7 is rated as "massive". There are approximately 50,000 LoRAs available on Civitai. Each LoRA adds roughly 0.1 GB of extra VRAM.
On a reference GPU (RTX 4090 24GB), LCM DreamShaper v7 generates a 1024×1024 image in approximately 300ms at FP16 with 28 inference steps. Faster GPUs with higher memory bandwidth will produce images more quickly.
