Ultra Fast Inference With Schnell Variant 1 4 Step Generation

via “ultra-fast inference with schnell variant (1-4 step generation)”

Black Forest Labs' flow-matching image model from SD creators.

Unique: Achieves 1-4 step generation through guidance distillation (removing classifier-free guidance overhead) combined with flow matching architecture, enabling sub-second latency without requiring model quantization or pruning

vs others: Faster than Stable Diffusion XL Turbo (which requires 1 step) while maintaining better quality; lower latency than standard FLUX.1 Pro with acceptable quality tradeoff for interactive applications
