Comments:
Hi @1TomLiu, I posted on another PR here: https://github.com/huggingface/transformers/pull/31690#issuecomment-2196594285 regarding the opening and closing of many PRs

Is there anything we can help with regarding this model addition?

We have recently been trying to push for model on the hub and have as much support as we can there. It's the easiest and recommended way to integrate into transformers. Here is a [tutorial](https://huggingface.co/docs/transformers/custom_models) if that sound good to you!
