+# dspy.Bedrock, dspy.Sagemaker
+
+### Usage
+
+The `AWSProvider` class is the base class for the AWS providers - `dspy.Bedrock` and `dspy.Sagemaker`. An instance of one of these providers is passed to the constructor when creating an instance of an AWS model class (e.g., `dspy.AWSMistral`) that is ultimately used to query the model.
+
+```python
+# Notes:
+# 1. Install boto3 to use AWS models.
+# 2. Configure your AWS credentials with the AWS CLI before using these models
+
+# initialize the bedrock aws provider
+bedrock = dspy.Bedrock(region_name="us-west-2")
+
+# initialize the sagemaker aws provider
+sagemaker = dspy.Sagemaker(region_name="us-west-2")
+```
+
+### Constructor
+
+The `Bedrock` constructor initializes the base class `AWSProvider`.
+
+```python
+class Bedrock(AWSProvider):
+    """This class adds support for Bedrock models."""
+
+    def __init__(
+        self,
+        region_name: str,
+        profile_name: Optional[str] = None,
+        batch_n_enabled: bool = False,   # This has to be setup manually on Bedrock.
+    ) -> None:
+```
+
+**Parameters:**
+- `region_name` (str): The AWS region where this LM is hosted.
+- `profile_name` (str, optional): boto3 credentials profile.
+- `batch_n_enabled` (bool): If False, call the LM N times rather than batching.
+
+### Methods
+
+```python
+def call_model(self, model_id: str, body: str) -> str:
+```
+This function implements the actual invocation of the model on AWS using the boto3 provider.
+
+<br/>
+
+`Sagemaker` works exactly the same as `Bedrock`.
