 As you may have noticed, you can select to work with `"hf-inference"` provider. This is what used to be the "Inference API (serverless)" prior to the Inference Providers integration. From a user point of view, working with HF Inference is the same as with any other providers. Past the free-tier credits, you get charged for every inference request based on the compute time x price of the underlying hardware.
