IP-Adapter is a lightweight adapter that enables prompting a diffusion model with an image. This method decouples the cross-attention layers of the image and text features. The image features are generated from an image encoder.
Learn how to load an IP-Adapter checkpoint and image in the IP-Adapter loading guide, and you can see how to use it in the usage guide.
Mixin for handling IP Adapters.

Parameters
str
or os.PathLike
or dict
) —
Can be either:
google/ddpm-celebahq-256
) of a pretrained model hosted on
the Hub../my_model_directory
) containing the model weights saved
with ModelMixin.save_pretrained().Union[str, os.PathLike]
, optional) —
Path to a directory where a downloaded pretrained model configuration is cached if the standard cache
is not used. bool
, optional, defaults to False
) —
Whether or not to force the (re-)download of the model weights and configuration files, overriding the
cached versions if they exist. bool
, optional, defaults to False
) —
Whether or not to resume downloading the model weights and configuration files. If set to False
, any
incompletely downloaded files are deleted. Dict[str, str]
, optional) —
A dictionary of proxy servers to use by protocol or endpoint, for example, {'http': 'foo.bar:3128', 'http://hostname': 'foo.bar:4012'}
. The proxies are used on each request. bool
, optional, defaults to False
) —
Whether to only load local model weights and configuration files or not. If set to True
, the model
won’t be downloaded from the Hub. str
or bool, optional) —
The token to use as HTTP bearer authorization for remote files. If True
, the token generated from
diffusers-cli login
(stored in ~/.huggingface
) is used. str
, optional, defaults to "main"
) —
The specific model version to use. It can be a branch name, a tag name, a commit id, or any identifier
allowed by Git. str
, optional, defaults to ""
) —
The subfolder location of a model file within a larger model repository on the Hub or locally. bool
, optional, defaults to True
if torch version >= 1.9.0 else False
) —
Speed up model loading only loading the pretrained weights and not initializing the weights. This also
tries to not use more than 1x model size in CPU memory (including peak memory) while loading the model.
Only supported for PyTorch >= 1.9.0. If you are using an older version of PyTorch, setting this
argument to True
will raise an error. Sets the conditioning scale between text and image.
