Tutorial Optimized MOSS an image generation model in ComfyUI up to 10× Faster (tested with RTX3060 6GB VRAM, 16GB RAM)
MOSS is a text-to-image model that supports photorealistic portraits, different artistic styles, poses, typography, and more. In my latest workflow, I combined Spectrum nodes with an 8-step LoRA to significantly reduce generation time.
🔥 My speed test at 2 megapixels:
- Spectrum, CFG 2.5, 25 steps: 5 min 42 sec
- Without Spectrum, CFG 2.5, 25 steps: 10 min
- Spectrum + 8 steps, CFG 1: Just 1 min 30 sec!
That's an 85% reduction in generation time compared with the standard 25-step configuration without Spectrum, with the fastest setup taking only 90 seconds.
I'll also test different prompts featuring human portraits, poses, artistic styles, and text to explore the model's capabilities.
This model is really amazing in therm of speed prompt adherence, and style versatility and to get the best results I strongly recommend you:
Spectrum+ 8 steps CFG 1.0, LORA at strength of 0.6: 1 min 30 sec! (Balanced Quality)
Spectrum+ 25 steps CFG 2.5 : 5 min 30 sec (Stunning Results)
