Hugging Face Model Not Supported
I have a question about the ARC "Hugging Face" Robot Skill.
I set up the API as instructed. I'm using a USB webcam (connected directly to the PC running ARC) and enabled "face" and "motion" tracking. I tried the first example from the Hugging Face Skill documentation, but all I get is this error:
enabled.","type":"invalid_request_error","param":"model","code":"model_not_supported"}}
20:55:27 Error: HTTP 400 from Hugging Face. {"error":{"message":"The requested model 'Qwen/Qwen2.5-VL-7B-Instruct' is not supported by any provider you have enabled.","type":"invalid_request_error","param":"model","code":"model_not_supported"}}
What am I missing?

Connects your robot camera to Hugging Face AI models for vision chat, object tracking, classification, captioning, and autonomous movement.
Requires ARC
v1

That error is coming from Hugging Face’s provider routing, not from ARC itself.
What it means
Qwen/Qwen2.5-VL-7B-Instructis a vision-language model, and Hugging Face is saying:So ARC is successfully sending the request, but Hugging Face is rejecting the model because your account/token/provider setup doesn’t have access to a backend that can run it.
What to check
1) Verify the model supports the task you chose
In the Hugging Face skill configuration, make sure you’re using the correct task:
If you enabled face and motion tracking, that sounds more like Object Detection, not Vision Chat.
2) Try a known-good default model for the selected task
In the skill’s kebab/gear menu configuration, switch to Default for that task and test again.
For example:
facebook/detr-resnet-50Salesforce/blip-image-captioning-largeThese are generally easier to get working than a large vision-chat model.
3) Check Hugging Face model access / provider availability
That specific error usually means one of these:
Hugging Face has a support article for model-based robot use in ARC here:
Important note about your webcam
Your USB webcam on the PC is fine. ARC can use that with the Camera Device skill. The webcam is not the issue here.
Make sure you have:
If the camera is not running, Hugging Face would usually complain about no active camera, not model support.
Best next step
Try this:
If that works, then the issue is specifically the Qwen vision-chat model/provider combo.
If you want Vision Chat
If your goal is the "robot sees and talks" behavior, you may need to:
Quick question
Are you trying to do:
If you tell me which task mode you selected in the skill, I can point you to the exact model/settings to use in ARC.
