 This package ports [chaiNNer](https://github.com/chaiNNer-org/chaiNNer)'s PyTorch architecture support and model loading functionality into its own package, and wraps it into an easy-to-use API.

+## File type support
+
+Spandrel mainly supports loading `.pth` files for all supported architectures. This is what you will typically find from official repos and community trained models. However, Spandrel also supports loading TorchScript traced models (`.pt`), certain types of `.ckpt` files, as well as any supported model that has been saved as or converted to a `.safetensors` file.
+
+## Security
+
+As you may know, loading `.pth` files usually [poses a security risk](https://github.com/pytorch/pytorch/issues/52596) due to python's `pickle` module being unsafe and vulnerable to arbitrary code execution (ACE). Because of this, Spandrel uses a custom unpickler function that only allows loading certain types of data out of a .pth file. This completely prevents ACE and makes loading untrusted files secure.

 ## Contributing
 
 Feel free to contribute more model architecture support. When I add model support, I usually dig through the .pth file (state dict) keys and weights to find a way to get all the parameters of a model. At some point, I will document that entire process here. For now, there are plenty of example to reference.
