# Models
The base class [`PreTrainedModel`] implements the common methods for loading/saving a model either from a local
file or directory, or from a pretrained model configuration provided by the library (downloaded from HuggingFace's Hub).
[`PreTrainedModel`] also implements a few methods which are common among all the models to:
- resize the input token embeddings when new tokens are added to the vocabulary
The other methods that are common to each model are defined in [`~modeling_utils.ModuleUtilsMixin`] and [`~generation.GenerationMixin`].
## PreTrainedModel
[[autodoc]] PreTrainedModel
- push_to_hub
- all
Custom models should also include a `_supports_assign_param_buffer`, which determines if superfast init can apply
on the particular model. Signs that your model needs this are if `test_save_and_load_from_pretrained` fails. If so,
set this to `False`.
