Deploy and check the mannequin utilizing SageMaker AI Inference

When deploying a fine-tuned mannequin on AWS, SageMaker AI Inference provides a number of deployment methods. On this publish, we use SageMaker real-time inference. The actual-time inference endpoint is designed for having full management over the inference assets. You should utilize a set of obtainable cases and deployment choices for internet hosting your mannequin. Through the use of the SageMaker built-in container DJL Serving, you may benefit from the inference script and optimization choices out there immediately within the container. On this publish, we deploy the fine-tuned mannequin to a SageMaker endpoint for operating inference, which will likely be used for testing the mannequin.

In SageMaker Unified Studio, in JupyterLab, we create the Mannequin object, which is a high-level SageMaker mannequin class for working with a number of container choices. The image_uri parameter specifies the container picture URI for the mannequin, and model_data factors to the Amazon S3 location containing the mannequin artifact (routinely uploaded by the SageMaker coaching job). We additionally specify a set of surroundings variables to configure the precise inference backend possibility (OPTION_ROLLING_BATCH), the diploma of tensor parallelism based mostly on the variety of out there GPUs (OPTION_TENSOR_PARALLEL_DEGREE), and the utmost allowable size of enter sequences (in tokens) for fashions throughout inference (OPTION_MAX_MODEL_LEN).

mannequin = Mannequin(
    image_uri=image_uri,
    model_data=f"s3://{bucket_name}/{job_prefix}/{job_name}/output/mannequin.tar.gz",
    position=get_execution_role(),
    env={
        'HF_MODEL_ID': "/decide/ml/mannequin",
        'OPTION_TRUST_REMOTE_CODE': 'true',
        'OPTION_ROLLING_BATCH': "vllm",
        'OPTION_DTYPE': 'bf16',
        'OPTION_TENSOR_PARALLEL_DEGREE': 'max',
        'OPTION_MAX_ROLLING_BATCH_SIZE': '1',
        'OPTION_MODEL_LOADING_TIMEOUT': '3600',
        'OPTION_MAX_MODEL_LEN': '4096'
    }
)

After you create the mannequin object, you may deploy it to an endpoint utilizing the deploy methodology. The initial_instance_count and instance_type parameters specify the quantity and sort of cases to make use of for the endpoint. We chosen the ml.g5.4xlarge occasion for the endpoint. The container_startup_health_check_timeout and model_data_download_timeout parameters set the timeout values for the container startup well being verify and mannequin knowledge obtain, respectively.

model_id = "deepseek-ai/DeepSeek-R1-Distill-Llama-8B"
endpoint_name = f"{model_id.cut up('/')[-1].exchange('.', '-')}-sft-djl"
predictor = mannequin.deploy(
    initial_instance_count=instance_count,
    instance_type=instance_type,
    container_startup_health_check_timeout=1800,
    model_data_download_timeout=3600
)

It takes a couple of minutes to deploy the mannequin earlier than it turns into out there for inference and analysis. You’ll be able to check the endpoint invocation in JupyterLab, through the use of the AWS SDK with the boto3 shopper for sagemaker-runtime, or through the use of the SageMaker Python SDK and the predictor beforehand created, through the use of the predict API.

base_prompt = f"""<s> [INST] {{query}} [/INST] """

immediate = base_prompt.format(
    query="What statue is in entrance of the Notre Dame constructing?"
)

predictor.predict({
    "inputs": immediate,
    "parameters": {
        "max_new_tokens": 300,
        "temperature": 0.2,
        "top_p": 0.9,
        "return_full_text": False,
        "cease": ['</s>']
    }
})

You may as well check the mannequin invocation in SageMaker Unified Studio, on the Inference endpoint web page and Textual content inference tab.
