 To load a custom pipeline you just need to pass the `custom_pipeline` argument to `DiffusionPipeline`, as one of the files in `diffusers/examples/community`. Feel free to send a PR with your own pipelines, we will merge them quickly.

+# Stable Diffusion 3 InstructPix2Pix Pipeline
+This the implementation of the Stable Diffusion 3 InstructPix2Pix Pipeline, based on the HuggingFace Diffusers.
+
+## Example Usage
+This pipeline aims to edit image based on user's instruction by using SD3
+````py
+import torch
+from diffusers import SD3Transformer2DModel
+from diffusers import DiffusionPipeline
+from diffusers.utils import load_image
+
+
+resolution = 512
+image = load_image("https://hf.co/datasets/diffusers/diffusers-images-docs/resolve/main/mountain.png").resize(
+    (resolution, resolution)
+)
+edit_instruction = "Turn sky into a sunny one"
+
+
+pipe = DiffusionPipeline.from_pretrained(
+    "stabilityai/stable-diffusion-3-medium-diffusers", custom_pipeline="pipeline_stable_diffusion_3_instruct_pix2pix", torch_dtype=torch.float16).to('cuda')
+
+pipe.transformer = SD3Transformer2DModel.from_pretrained("CaptainZZZ/sd3-instructpix2pix",torch_dtype=torch.float16).to('cuda')
+
+edited_image = pipe(
+    prompt=edit_instruction,
+    image=image,
+    height=resolution,
+    width=resolution,
+    guidance_scale=7.5,
+    image_guidance_scale=1.5,
+    num_inference_steps=30,
+).images[0]
+
+edited_image.save("edited_image.png")

+
+### Note
+This model is trained on 512x512, so input size is better on 512x512.
+For better editing performance, please refer to this powerful model https://huggingface.co/BleachNick/SD3_UltraEdit_freeform and Paper "UltraEdit: Instruction-based Fine-Grained Image
+Editing at Scale", many thanks to their contribution!
