The format of `repo_id` is correct, but since the model has not been deployed, it cannot be used as an API. Refer to the following post to find a model that can be used. Using a local model is more reliable, but requires a GPU. > [@Persistent 404 Not Found Errors with Public Inference API](https://discuss.huggingface.co/t/persistent-404-not-found-errors-with-public-inference-api/154119/10): > > Hi all, thanks for reporting! You can check to see if your model is available to use with the HF Inference API (or any Inference Provider) here: [Models - Hugging Face](https://huggingface.co/models?inference_provider=hf-inference&sort=trending). If it’s not deployed by any Inference Provider, you can request provider support on the model page. Please note Inference Endpoints is available to use - more info here: [Inference Endpoints](https://huggingface.co/docs/inference-endpoints/index).
