 # IP-Adapter

-The features of IP-Adapter in DiffSynth Studio is not completed. Please wait for us.
+IP-Adapter is a interesting model, which can adopt the content or style of another image to generate a new image.
+
+## Example: Content Controlling in Stable Diffusion
+
+Based on Stable Diffusion, we can transfer the object to another scene. See [`sd_ipadapter.py`](./sd_ipadapter.py).
+
+|First, we generate a car. The prompt is "masterpiece, best quality, a car".|Next, utilizing IP-Adapter, we move the car to the road. The prompt is "masterpiece, best quality, a car running on the road".|

+
+## Example: Content and Style Controlling in Stable Diffusion XL
+
+The IP-Adapter model based on Stable Diffusion XL is more powerful. You have the option to use the content or style. See [`sdxl_ipadapter.py`](./sdxl_ipadapter.py).
+
+* Content controlling (original usage of IP-Adapter)

+
+## Example: Image Fusing (Experimental)
+
+Since IP-Adapter can control the content based on more than one image, we can do something interesting. See [`sdxl_ipadapter_multi_reference.py`](sdxl_ipadapter_multi_reference.py).
