Any model repository with chat template(s) is supported (including GGUFs), however do note that all the model info is extracted using the Hugging Face API.
For GGUFs in particular this means that the chat template may deviate from the actual content in any given GGUF file as only the default template from an arbitrary GGUF file is returned.
If you sign in and grant this editor write access you will get the option to create a pull request of your changes (provided you have access to the repository).
You can freely edit and test GGUF chat template(s) (and are encouraged to do so), but you cannot commit any changes, it is recommended to use the [GGUF Editor](https://huggingface.co/spaces/CISCai/gguf-editor) to save the final result to a GGUF.
