 **⭐ Multiple Models ⭐**
 To serve multiple models in your deployment you can easily build a `config.yaml`. In the example below, we define two BERT models in our configuration for the question answering task:

 To serve multiple models you can build a `config.yaml` file. 
 In the sample YAML file below, we are defining two BERT models to be served by the `deepsparse.server` for the **question answering** task:
