Amazon SageMaker

Language Support

This provider is only supported in Python.

Amazon SageMaker is a fully managed machine learning service that provides infrastructure and tools for building, training, and deploying ML models at scale. The Strands Agents SDK implements a SageMaker provider, allowing you to run agents against models deployed on SageMaker inference endpoints, including both pre-trained models from SageMaker JumpStart and custom fine-tuned models. The provider is designed to work with models that support OpenAI-compatible chat completion APIs.

For example, you can expose models like Mistral-Small-24B-Instruct-2501 on SageMaker, which has demonstrated reliable performance for conversational AI and tool calling scenarios.

Installation

SageMaker is configured as an optional dependency in Strands Agents. To install, run:

pip install 'strands-agents[sagemaker]' strands-agents-tools

Usage

After installing the SageMaker dependencies, you can import and initialize the Strands Agents’ SageMaker provider as follows:

from strands import Agent
from strands.models.sagemaker import SageMakerAIModel
from strands_tools import calculator

model = SageMakerAIModel(
    endpoint_config={
        "endpoint_name": "my-llm-endpoint",
        "region_name": "us-west-2",
    },
    payload_config={
        "max_tokens": 1000,
        "temperature": 0.7,
        "stream": True,
    }
)

agent = Agent(model=model, tools=[calculator])
response = agent("What is the square root of 64?")

Note: Tool calling support varies by model. Models like Mistral-Small-24B-Instruct-2501 have demonstrated reliable tool calling capabilities, but not all models deployed on SageMaker support this feature. Verify your model’s capabilities before implementing tool-based workflows.

Configuration

Endpoint Configuration

The endpoint_config configures the SageMaker endpoint connection:

Parameter	Description	Required	Example
endpoint_name	Name of the SageMaker endpoint	Yes	"my-llm-endpoint"
region_name	AWS region where the endpoint is deployed	Yes	"us-west-2"
inference_component_name	Name of the inference component	No	"my-component"
target_model	Specific model to invoke (multi-model endpoints)	No	"model-a.tar.gz"
target_variant	Production variant to invoke	No	"variant-1"

Payload Configuration

The payload_config configures the model inference parameters:

Parameter	Description	Default	Example
max_tokens	Maximum number of tokens to generate	Required	1000
stream	Enable streaming responses	True	True
temperature	Sampling temperature (0.0 to 2.0)	Optional	0.7
top_p	Nucleus sampling parameter (0.0 to 1.0)	Optional	0.9
top_k	Top-k sampling parameter	Optional	50
stop	List of stop sequences	Optional	["Human:", "AI:"]

Model Compatibility

The SageMaker provider is designed to work with models that support OpenAI-compatible chat completion APIs. During development and testing, the provider has been validated with Mistral-Small-24B-Instruct-2501, which demonstrated reliable performance across various conversational AI tasks.

Important Considerations

• Model Performance: Results and capabilities vary significantly depending on the specific model deployed to your SageMaker endpoint
• Tool Calling Support: Not all models deployed on SageMaker support function/tool calling. Verify your model’s capabilities before implementing tool-based workflows
• API Compatibility: Ensure your deployed model accepts and returns data in the OpenAI chat completion format

For optimal results, we recommend testing your specific model deployment with your use case requirements before production deployment.

Troubleshooting

Module Not Found

If you encounter ModuleNotFoundError: No module named 'boto3' or similar, install the SageMaker dependencies:

pip install 'strands-agents[sagemaker]'

Authentication

The SageMaker provider uses standard AWS authentication methods (credentials file, environment variables, IAM roles, or AWS SSO). Ensure your AWS credentials have the necessary SageMaker invoke permissions.

Model Compatibility

Ensure your deployed model supports OpenAI-compatible chat completion APIs and verify tool calling capabilities if needed. Refer to the Model Compatibility section above for detailed requirements and testing recommendations.
