Mine stopped for a while too getting 503:
“503 Server Error: Service Temporarily Unavailable for url: https://router.huggingface.co/hf-inference/models/black-forest-labs/FLUX.1-schnell”
I looked that you could set a provider.
I changed the parameters to the following and it worked.
from huggingface_hub import InferenceClient
client = InferenceClient(
provider="fal-ai",
api_key="hf_xxxxxxxxxxxxxxxxxxxxxxxx",
)
Which you can find if you click view code on the model card.
Looks like maybe the router code is not functioning properly. I could only speculate but potential issue there.
