I using hugging face unity api in my project. It work good until today. When its start doing request its gives error 404 on 3 modules. Like this: Attempted request to [https://api-inference.huggingface.co/models/facebook/wav2vec2-base-960h](https://api-inference.huggingface.co/models/facebook/wav2vec2-base-960h) failed: HTTP/1.1 404 Not Found - Not Found. I update token, check versions of models and everything is fine. Read forums, saw the same problem the day before. No one is answering. Git for Hugging Face Unity API: [GitHub - huggingface/unity-api](https://github.com/huggingface/unity-api.git)

Currently, the API is not functioning properly. Roughly speaking, there are at least three types of issues occurring simultaneously.

I was successfully using it for image-to-image tasks (specifically with models like stabilityai/stable-diffusion-xl-refiner-1.0), but it abruptly stopped working a short while ago. Now, regardless of which model I try to use, I consistently receive the following error pattern: Model \<model\_name\> is not supported HF inference api This is happening in two distinct ways: Via InferenceClient: My applicat…

The retry error and SentenceTransformers issue of them have been resolved.

I still see 404 for private models that are accessible with HF tokens.

I am just downloading a private model using AutoTokenizer.from\_pretrained(model\_name, token=hf\_token).  
And I see this error (redacted model name):

I think the program is not passing tokens when searching for template files, causing an error in requests. However, there is no such part in the AutoTokenizer code itself, so I think it is in the code of the specific Tokenizer class that is actually called.

If I know which model’s Tokenizer is being used, that would be a clue…
