Inference API stopped working

[rockmatas]

Hi everyone,

I seem to be encountering a sudden issue with the Hugging Face Inference API. 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:

1. Via InferenceClient: My application code, which was previously working, now gets this error for any model inference request.
2. Via Website Inference Widget: Even trying to use the Inference Widget directly on the model pages on the Hugging Face website results in the same error message appearing where the widget interface should be.

Here are a couple of specific examples I’ve tested:

• Model: timbrooks/instruct-pix2pix
  • Link: timbrooks/instruct-pix2pix · Hugging Face
  • Output: Model timbrooks/instruct-pix2pix inference is not supported HF inference api
• Model: stabilityai/stable-diffusion-xl-refiner-1.0
  • Link: stabilityai/stable-diffusion-xl-refiner-1.0 · Hugging Face
  • Output: Model stabilityai/stable-diffusion-xl-refiner-1.0 inference is not supported HF inference api
    (Note: I’ve tried several others with the same result)

Since this is affecting multiple models and occurs both through the API client and the website widget, it feels like it might be a broader issue rather than something specific to my setup or a single model.

Is anyone else experiencing similar behavior? Any information or confirmation would be greatly appreciated!

Thanks!

We are seeing 404 error on these two
{“error”:“Model nvidia/cycle-diffusion does not exist”} Status: 404
{“error”:“Model yisol/IDM-VTON inference is not supported HF inference api”} Status: 404

Probably the same thing happened.

404 - "{\"error\":\"Model XLabs-AI/flux-RealismLora does not exist\"}"

I am using model via hugging inference API in n8n , it was working fine till yesterday, now its giving me this response: 404 - “{"error":"Model XLabs-AI/flux-RealismLora does not exist"}” [image] Thanks in advance

Hi there.
The issue persists across all models, even in multi-model Spaces like:
40 Models - a Hugging Face Space by Uthar

every request fails with:
‘Could not complete request to HuggingFace API, Status Code: 404, Error: Model (…) inference is not supported by HF inference API’.

I wonder if this will even get fixed or the model creators need to create new interfence api setup

[John6666]

It’s probably both. Since a renewal is being carried out that will eventually only allow the so-called Warm model to be used, it will ultimately be a battle for the entry slots, excluding the famous models.
