While Xet brings fine-grained deduplication and enhanced performance to Git-based storage, some features and platform compatibilities are still in development. As a result, keep the following constraints in mind when working with a Xet-enabled repository:

- **64-bit systems only**: The hf_xet client currently requires a 64-bit architecture; 32-bit systems are not supported.
- **64-bit systems only**: The `hf_xet` client currently requires a 64-bit architecture; 32-bit systems are not supported.
- **Partial JavaScript library support**: The [huggingface.js](https://huggingface.co/docs/huggingface.js/index) library has limited functionality with Xet-backed repositories; additional coverage is planned in future releases.
- **Full web support currently unavailable**: Full support for chunked uploads via the Hub web interface remains under development.
- **No EU region support**: Support for EU [storage regions](https://huggingface.co/docs/hub/storage-regions) with Xet-backed repositories is planned but remains under development.
- **Git client integration (git-xet)**: Planned but remains under development.
