Getting ‘400 Client Error: Bad Request for url’ error while trying out the widgets of sentence- similarity task. ![image](https://us1.discourse-cdn.com/hellohellohello/original/2X/d/d20a5a52808b6edae439777731aa875f657c82ef.png) Faced this issue while trying to use many sentence-similarity models uploaded in the last 2 months: (Mentioning the names of few models for example) l3cube-pune/indic-sentence-similarity-sbert l3cube-pune/indic-sentence-bert-nli l3cube-pune/hindi-sentence-bert-nli Is this some problem with the model or it this a problem related to HF inference API? Any help regarding how to fix this error would be appreciated. Thanks ---

@ananya20 did you find a solution? I’m facing the same issue. it is working locally, but the pushed version on HG throws the same error. ---

@bayang I haven’t found a solution yet. I could see this error in most sentence-similarity models pushed on Hugging Face recently. I do not think this is an issue with the model files ---

@ananya20 Exactly my model is working offline when I call my private model using `use_auth_token`, it works perfectly locally. If we were able to see and modify the code behind their free API inferencing, this could be great. ---

The issue seems to be resolved now. The error is gone and APIs are working well. ---

You are right, it is also working on my side:) ---

I am using a text to image model and still getting this error on my deployed website. Anybody has an idea why? ---

The Inference API specification has changed since the summer, making it almost unusable unless the model is in **Warm** status. > **[Supported Models](https://huggingface.co/docs/api-inference/supported-models)** > > We’re on a journey to advance and democratize artificial intelligence through open source and open science.
