+
+[*Spatiotemporal Skip Guidance (STG) for Enhanced Video Diffusion Sampling*](https://arxiv.org/abs/2411.18664) (CVPR 2025) is a simple training-free sampling guidance method for enhancing transformer-based video diffusion models. STG employs an implicit weak model via self-perturbation, avoiding the need for external models or additional training. By selectively skipping spatiotemporal layers, STG produces an aligned, degraded version of the original model to boost sample quality without compromising diversity or dynamic degree.
+
+Following is the example video of STG applied to Mochi.

+#### Usage example

+from pipeline_stg_mochi import MochiSTGPipeline

+
+# Load the pipeline
+pipe = MochiSTGPipeline.from_pretrained("genmo/mochi-1-preview", variant="bf16", torch_dtype=torch.bfloat16)
+
+# Enable memory savings
+pipe = pipe.to("cuda")
+
+#--------Option--------#
+prompt = "A close-up of a beautiful woman's face with colored powder exploding around her, creating an abstract splash of vibrant hues, realistic style."
+stg_applied_layers_idx = [34]
+stg_mode = "STG"
+stg_scale = 1.0 # 0.0 for CFG
+#----------------------#
+
+# Generate video frames
+frames = pipe(

+    width=480,
+    num_frames=81,
+    stg_applied_layers_idx=stg_applied_layers_idx,
