| # Security Policy | |
| ## Hugging Face Hub, remote artefacts, and remote code | |
| Transformers is open-source software that is tightly coupled to the Hugging Face Hub. While you have the ability to use it | |
| offline with pre-downloaded model weights, it provides a very simple way to download, use, and manage models locally. | |
| When downloading artefacts that have been uploaded by others on any platform, you expose yourself to risks. Please | |
| read below for the security recommendations in order to keep your runtime and local environment safe. | |
| ### Remote artefacts | |
| Models uploaded on the Hugging Face Hub come in different formats. We heavily recommend uploading and downloading | |
| models in the [`safetensors`](https://github.com/huggingface/safetensors) format (which is the default prioritized | |
| by the transformers library), as developed specifically to prevent arbitrary code execution on your system. | |
| To avoid loading models from unsafe formats(e.g. [pickle](https://docs.python.org/3/library/pickle.html), you should use the `use_safetenstors` parameter. If doing so, in the event that no .safetensors file is present, transformers will error when loading the model. | |
| ### Remote code | |
| #### Modeling | |
| Transformers supports many model architectures, but is also the bridge between your Python runtime and models that | |
| are stored in model repositories on the Hugging Face Hub. | |
| These models require the `trust_remote_code=True` parameter to be set when using them; please **always** verify | |
| the content of the modeling files when using this argument. We recommend setting a revision in order to ensure you | |
| protect yourself from updates on the repository. | |
| #### Tools | |
| Through the `Agent` framework, remote tools can be downloaded to be used by the Agent. You're to specify these tools | |
| yourself, but please keep in mind that their code will be run on your machine if the Agent chooses to run them. | |
| Please inspect the code of the tools before passing them to the Agent to protect your runtime and local setup. | |
| ## Reporting a Vulnerability | |
