Amazon SageMaker Pipelines  helps you create fully automated ML workflows from data preparation through model deployment so you can scale to thousands of ML models in production. You can create Pipelines with the SageMaker Python SDK and view, execute, audit them from the visual interface of the SageMaker Studio. SageMaker Pipelines takes care of managing data between steps, packaging the code recipes, and orchestrating their execution, reducing months of coding to a few hours. Every time a workflow executes, a complete record of the data processed and actions taken is kept so data scientists and ML developers can quickly debug problems.

A SageMaker Pipeline is composed of ‘steps’. You can choose any of the natively supported step types to compose a workflow that invokes various SageMaker AI features (eg. training, evaluation) or other AWS services (eg. EMR, Lambda). You can also lift-and-shift your existing ML Python code into SageMaker Pipeline by either using the ‘@step’ python decorator or adding entire python Notebooks as components of the Pipeline. For additional details, please refer to the SageMaker Pipelines developer guide.

There is no additional charge for SageMaker Pipelines. You pay only for the underlying compute or any separate AWS services you use within SageMaker Pipelines.

Yes. Amazon SageMaker AI Components for Kubeflow Pipelines are open-source plugins that allow you to use Kubeflow Pipelines to define your ML workflows and use SageMaker AI for the data labeling, training, and inference steps. Kubeflow Pipelines is an add-on to Kubeflow that lets you build and deploy portable and scalable complete ML pipelines. However, when using Kubeflow Pipelines, ML ops teams need to manage a Kubernetes cluster with CPU and GPU instances and keep its utilization high at all times to reduce operational costs. Maximizing the utilization of a cluster across data science teams is challenging and adds additional operational overhead to the ML ops teams. As an alternative to an ML-optimized Kubernetes cluster, with SageMaker Components for Kubeflow Pipelines you can take advantage of powerful SageMaker features such as data labeling, fully managed large-scale hyperparameter tuning and distributed training jobs, one-click secure and scalable model deployment, and cost-effective training through Amazon Elastic Compute Cloud (Amazon EC2) Spot Instances without needing to configure and manage Kubernetes clusters specifically to run the ML jobs.

There is no additional charge for using SageMaker Components for Kubeflow Pipelines. 

Human-in-the-loop is the process of harnessing human input across the ML lifecycle to improve the accuracy and relevancy of models. Humans can perform a variety of tasks, from data generation and annotation, to model review and customization. Human intervention is especially important for generative AI applications, where humans are typically both the requester and consumer of the content. It is therefore critical that humans train foundation models (FMs) how to respond accurately, safely, and relevantly to users’ prompts. Human feedback can be applied to help you complete multiple tasks. First, creating high quality labeled training datasets for generative AI applications via supervised learning (where a human simulates the style, length, and accuracy of how a model should respond to user’s prompts) and reinforcement learning with human feedback (where a human ranks and classifies model responses). Second, using human-generated data to customize FMs on specific tasks or with your company and domain specific data and make model output relevant for you.

Human-in-the-loop capabilities play an important role in creating and improving generative AI applications powered by FMs. A highly skilled human workforce that is trained on the tasks’ guidelines can provide feedback, guidance, inputs, and assessment in activities like generating demonstration data to train FMs, correcting and improving sample responses, fine-tuning a model based on company and industry data, acting as a safeguard against toxicity and bias and more. Human-in-the-loop capabilities, therefore, can improve model accuracy and performance.

You can use fully managed Jupyter notebooks in SageMaker AI for the complete ML development. Scale compute instances up and down with the board selection of compute-optimized and GPU-accelerated instances in the cloud.

SageMaker Studio notebooks are one-step Jupyter notebooks that can be spun quickly. The underlying compute resources are fully elastic, so you can easily dial up or down the available resources and the changes take place automatically in the background without interrupting your work. SageMaker AI also enables one-step sharing of notebooks. You can easily share notebooks with others and they’ll get the exact same notebook, saved in the same place.

With SageMaker Studio notebooks, you can sign in with your corporate credentials using IAM Identity Center. Sharing notebooks within and across teams is easy since the dependencies needed to run a notebook are automatically tracked in work images that are encapsulated with the notebook as it is shared.

Notebooks in SageMaker Studio IDEs offer a few important features that differentiate them from the instance-based notebooks. First, you can quickly launch notebooks without needing to manually provision an instance and waiting for it to be operational. The startup time of launching the UI to read and execute a notebook is faster than the instance-based notebooks. You also have the flexibility to choose from a large collection of instance types from within the UI at any time. You do not need to go to the AWS Management Console to start new instances and port over your notebooks. Each user has an isolated home directory independent of a particular instance. This directory is automatically mounted into all notebook servers and kernels as they’re started, so you can access your notebooks and other files even when you switch instances to view and run your notebooks. SageMaker Studio notebooks are integrated with AWS IAM Identity Center (successor to AWS SSO), making it easier to use your organizational credentials to access the notebooks. They are also integrated with purpose-built ML tools in SageMaker AI and other AWS services for your complete ML development, from preparing data at petabyte scale using Spark on Amazon EMR, training and debugging models, to deploying and monitoring models and managing pipelines.

ML practitioners can create a shared workspace where teammates can read and edit SageMaker Studio notebooks together. By using the shared paces, teammates can coedit the same notebook file, run notebook code simultaneously, and review the results together to eliminate back and forth and streamline collaboration. In the shared spaces, ML teams will have built-in support for services like BitBucket and AWS CodeCommit, so they can easily manage different versions of their notebook and compare changes over time. Any resources created from within the notebooks, such as experiments and ML models, are automatically saved and associated with the specific workspace where they were created so teams can more easily stay organized and accelerate ML model development.

You pay for both compute and storage when you use SageMaker AI notebooks in Studio IDEs. See Amazon SageMaker AI Pricing for charges by compute instance type. Your notebooks and associated artifacts such as data files and scripts are persisted on Amazon Elastic File System (Amazon EFS). See Amazon EFS Pricing for storage charges. As part of the AWS Free Tier, you can get started with notebooks in SageMaker Studio for free.

No. You can create and run multiple notebooks on the same compute instance. You pay only for the compute that you use, not for individual items. You can read more about this in our metering guide .

In addition to the notebooks, you can also start and run terminals and interactive shells in SageMaker Studio, all on the same compute instance. Each application runs within a container or image. SageMaker Studio provides several built-in images purpose-built and preconfigured for data science and ML.

You can monitor and shut down the resources used by your SageMaker Studio notebooks through both SageMaker Studio visual interface and the AWS Management Console. See the documentation for more details.

No, you don’t get charged for creating or configuring an SageMaker Studio domain, including adding, updating, and deleting user profiles.

SageMaker Canvas is a visual drag-and-drop service that allows business analysts to build ML models and generate accurate predictions without writing any code or requiring ML expertise. SageMaker Canvas makes it easier to access and combine data from a variety of sources, automatically clean data and apply a variety of data adjustments, and build ML models to generate accurate predictions in a single step. You can also easily publish results, explain and interpret models, and share models with others within your organization to review.

SageMaker Canvas helps you seamlessly discover AWS data sources that your account has access to, including Amazon S3 and Amazon Redshift. You can browse and import data using the SageMaker Canvas visual drag-and-drop interface. Additionally, you can drag and drop files from your local disk, and use pre-built connectors to import data from third-party sources such as Snowflake.

Once you have connected sources, selected a dataset, and prepared your data, you can select the target column that you want to predict to initiate a model creation job. SageMaker Canvas will automatically identify the problem type, generate new relevant features, test a comprehensive set of prediction models using ML techniques such as linear regression, logistic regression, deep learning, time-series forecasting, and gradient boosting, and build the model that makes accurate predictions based on your dataset.

The time it takes to build a model depends on the size of your dataset. Small datasets can take less than 30 minutes, and large datasets can take a few hours. As the model creation job progresses, SageMaker Canvas provides detailed visual updates, including percent job complete and the amount of time left for job completion.

Yes. SageMaker AI can automatically distribute deep learning models and large training sets across AWS GPU instances in a fraction of the time it takes to build and optimize these distribution strategies manually. The two distributed training techniques that SageMaker AI applies are data parallelism and model parallelism. Data parallelism is applied to improve training speeds by dividing the data equally across multiple GPU instances, allowing each instance to train concurrently. Model parallelism is useful for models too large to be stored on a single GPU and require the model to be partitioned into smaller parts before distributing across multiple GPUs. With only a few lines of additional code in your PyTorch and TensorFlow training scripts, SageMaker AI will automatically apply data parallelism or model parallelism for you, allowing you to develop and deploy your models faster. SageMaker AI will determine the best approach to split your model by using graph partitioning algorithms to balance the computation of each GPU while minimizing the communication between GPU instances. SageMaker AI also optimizes your distributed training jobs through algorithms that fully utilize the AWS compute and network in order to achieve near-linear scaling efficiency, which allows you to complete training faster than manual open-source implementations.

SageMaker Training Compiler is a deep learning (DL) compiler that accelerates DL model training by up to 50 percent through graph- and kernel-level optimizations to use GPUs more efficiently. SageMaker Training Compiler is integrated with versions of TensorFlow and PyTorch in SageMaker, so you can speed up training in these popular frameworks with minimal code changes.

SageMaker Training Compiler accelerates training jobs by converting DL models from their high-level language representation to hardware-optimized instructions that train faster than jobs with the native frameworks. More specifically, SageMaker Training Compiler uses graph-level optimization (operator fusion, memory planning, and algebraic simplification), data flow-level optimizations (layout transformation, common sub-expression elimination), and backend optimizations (memory latency hiding, loop oriented optimizations) to produce an optimized model training job that more efficiently uses hardware resources and, as a result, trains faster.

Managed Spot Training with SageMaker AI lets you train your ML models using Amazon EC2 Spot Instances, while reducing the cost of training your models by up to 90%.

SageMaker Training Compiler is built into the SageMaker Python SDK and SageMaker Hugging Face Deep Learning Containers. You don’t need to change your workflows to access its speedup benefits. You can run training jobs in the same way as you already do, using any of the SageMaker interfaces: SageMaker notebook instances, SageMaker Studio, AWS SDK for Python (Boto3), and AWS Command Line Interface (AWS CLI). You can enable SageMaker Training Compiler by adding a TrainingCompilerConfig class as a parameter when you create a framework estimator object. Practically, this means a couple of lines of code added to your existing training job script for a single GPU instance. Most up-to-date detailed documentation, sample notebooks, and examples are available in the documentation .

SageMaker Training Compiler is a SageMaker Training feature and is provided at no additional charge exclusively to SageMaker AI customers. Customers can actually reduce their costs with SageMaker Training Compiler as training times are reduced.

You enable the Managed Spot Training option when submitting your training jobs and you also specify how long you want to wait for Spot capacity. SageMaker AI will then use Amazon EC2 Spot Instances to run your job and manages the Spot capacity. You have full visibility into the status of your training jobs, both while they are running and while they are waiting for capacity.

Managed Spot Training uses Amazon EC2 Spot Instances for training, and these instances can be pre-empted when AWS needs capacity. As a result, Managed Spot Training jobs can run in small increments as and when capacity becomes available. The training jobs need not be restarted from scratch when there is an interruption, as SageMaker AI can resume the training jobs using the latest model checkpoint. The built-in frameworks and the built-in computer vision algorithms with SageMaker AI enable periodic checkpoints, and you can enable checkpoints with custom models.

We recommend periodic checkpoints as a general best practice for long-running training jobs. This prevents your Managed Spot Training jobs from restarting if capacity is pre-empted. When you enable checkpoints, SageMaker AI resumes your Managed Spot Training jobs from the last checkpoint.

Managed Spot Training can be used with all instances supported in SageMaker AI.

Managed Spot Training is supported in all Regions where SageMaker AI is currently available .

There are no fixed limits to the size of the dataset you can use for training models with SageMaker AI.

SageMaker AI includes built-in algorithms for linear regression, logistic regression, k-means clustering, principal component analysis, factorization machines, neural topic modeling, latent dirichlet allocation, gradient boosted trees, sequence2sequence, time-series forecasting, word2vec, and image classification. SageMaker AI also provides optimized Apache MXNet, Tensorflow, Chainer, PyTorch, Gluon, Keras, Horovod, Scikit-learn, and Deep Graph Library containers. In addition, SageMaker AI supports your custom training algorithms provided through a Docker image adhering to the documented specification.

You can run automatic model tuning in SageMaker AI on top of any algorithm as long as it’s scientifically feasible, including built-in SageMaker AI algorithms, deep neural networks, or arbitrary algorithms you bring to SageMaker AI in the form of Docker images.

Not at this time. The best model tuning performance and experience is within SageMaker AI.

Currently, the algorithm for tuning hyperparameters is a customized implementation of Bayesian Optimization. It aims to optimize a customer-specified objective metric throughout the tuning process. Specifically, it checks the object metric of completed training jobs, and uses the knowledge to infer the hyperparameter combination for the next training job.

No. How certain hyperparameters impact the model performance depends on various factors, and it is hard to definitively say one hyperparameter is more important than the others and thus needs to be tuned. For built-in algorithms within SageMaker AI, we do call out whether or not a hyperparameter is tunable.

The length of time for a hyperparameter tuning job depends on multiple factors, including the size of the data, the underlying algorithm, and the values of the hyperparameters. Additionally, customers can choose the number of simultaneous training jobs and total number of training jobs. All these choices affect how long a hyperparameter tuning job can last.

Not at this time. Currently, you need to specify a single objective metric to optimize or change your algorithm code to emit a new metric, which is a weighted average between two or more useful metrics, and have the tuning process optimize towards that objective metric.

There is no charge for a hyperparameter tuning job itself. You will be charged by the training jobs that are launched by the hyperparameter tuning job, based on model training pricing .

SageMaker Autopilot automates everything in a typical ML workflow, including feature preprocessing, algorithm selection, and hyperparameter tuning, while specifically focusing on classification and regression use cases. Automatic Model Tuning, on the other hand, is designed to tune any model, no matter whether it is based on built-in algorithms, deep learning frameworks, or custom containers. In exchange for the flexibility, you have to manually pick the specific algorithm, hyperparameters to tune, and corresponding search ranges.

Reinforcement learning is a ML technique that enables an agent to learn in an interactive environment by trial and error using feedback from its own actions and experiences.

Yes, you can train reinforcement learning models in SageMaker AI in addition to supervised and unsupervised learning models.

Though both supervised and reinforcement learning use mapping between input and output, unlike supervised learning where the feedback provided to the agent is the correct set of actions for performing a task, reinforcement learning uses a delayed feedback where reward signals are optimized to ensure a long-term goal through a sequence of actions.

While the goal of supervised learning techniques is to find the right answer based on the patterns in the training data, the goal of unsupervised learning techniques is to find similarities and differences between data points. In contrast, the goal of reinforcement learning (RL) techniques is to learn how to achieve a desired outcome even when it is not clear how to accomplish that outcome. As a result, RL is more suited to enabling intelligent applications where an agent can make autonomous decisions such as robotics, autonomous vehicles, HVAC, industrial control, and more.

Amazon SageMaker RL supports a number of different environments for training RL models. You can use AWS services such as AWS RoboMaker, open-source environments or custom environments developed using Open AI Gym interfaces, or commercial simulation environments such as MATLAB and SimuLink.

No, SageMaker RL includes RL toolkits such as Coach and Ray RLLib that offer implementations of RL agent algorithms such as DQN, PPO, A3C, and many more.

Yes, you can bring your own RL libraries and algorithm implementations in Docker Containers and run those in SageMaker RL.

Yes. You can even select a heterogeneous cluster where the training can run on a GPU instance and the simulations can run on multiple CPU instances.

After you build and train models, SageMaker AI provides three options to deploy them so you can start making predictions. Real-time inference is suitable for workloads with millisecond latency requirements, payload sizes up to 6 MB, and processing times of up to 60 seconds. Batch transform is ideal for offline predictions on large batches of data that are available up front. Asynchronous inference is designed for workloads that do not have sub-second latency requirements, payload sizes up to 1 GB, and processing times of up to 15 minutes.

You can scale down the SageMaker Asynchronous Inference endpoint instance count to zero in order to save on costs when you are not actively processing requests. You need to define a scaling policy that scales on the "ApproximateBacklogPerInstance" custom metric and set the "MinCapacity" value to zero. For step-by-step instructions, please visit the autoscale an asynchronous endpoint section of the developer guide. 

SageMaker Serverless Inference is a purpose-built serverless model serving option that makes it easy to deploy and scale ML models. SageMaker Serverless Inference endpoints automatically start the compute resources and scale them in and out depending on traffic, eliminating the need for you to choose instance type, run provisioned capacity, or manage scaling. You can optionally specify the memory requirements for your serverless inference endpoint. You pay only for the duration of running the inference code and the amount of data processed, not for idle periods.

With on-demand serverless endpoints, if your endpoint does not receive traffic for a while and then your endpoint suddenly receives new requests, it can take some time for your endpoint to spin up the compute resources to process the requests. This is called a cold start. A cold start can also occur if your concurrent requests exceed the current concurrent request usage. The cold start time depends on your model size, how long it takes to download your model, and the start-up time of your container.

To reduce variability in your latency profile, you can optionally enable Provisioned Concurrency for your serverless endpoints. With Provisioned Concurrency, your serverless endpoints are always ready and can instantaneously serve bursts in traffic, without any cold starts.

As with on-demand Serverless Inference, when Provisioned Concurrency is enabled, you pay for the compute capacity used to process inference requests, billed by the millisecond, and the amount of data processed. You also pay for Provisioned Concurrency usage, based on the memory configured, duration provisioned, and amount of concurrency enabled. For more information, see Amazon SageMaker AI Pricing.

SageMaker AI helps you run shadow tests to evaluate a new ML model before production release by testing its performance against the currently deployed model. SageMaker AI deploys the new model in shadow mode alongside the current production model and mirrors a user-specified portion of the production traffic to the new model. It optionally logs the model inferences for offline comparison. It also provides a live dashboard with a comparison of key performance metrics, such as latency and error rate, between the production and shadow models to help you decide whether to promote the new model to production.

SageMaker AI simplifies the process of setting up and monitoring shadow variants so you can evaluate the performance of the new ML model on live production traffic. SageMaker AI eliminates the need for you to orchestrate infrastructure for shadow testing. It lets you control testing parameters such as the percentage of traffic mirrored to the shadow variant and the duration of the test. As a result, you can start small and increase the inference requests to the new model after you gain confidence in model performance. SageMaker AI creates a live dashboard displaying performance differences across key metrics, so you can easily compare model performance to evaluate how the new model differs from the production model.

SageMaker Inference Recommender  reduces the time required to get ML models in production by automating performance benchmarking and tuning model performance across SageMaker ML instances. You can now use SageMaker Inference Recommender to deploy your model to an endpoint that delivers the best performance and minimizes cost. You can get started with SageMaker Inference Recommender in minutes while selecting an instance type and get recommendations for optimal endpoint configurations within hours, eliminating weeks of manual testing and tuning time. With SageMaker Inference Recommender, you pay only for the SageMaker ML instances used during load testing, and there are no additional charges.

No, we currently support only a single model per endpoint.

Currently we support only real-time endpoints.

We support all Regions supported by Amazon SageMaker, except the AWS China Regions.

Yes, we support all types of containers. Amazon EC2 Inf1, based on the AWS Inferentia chip, requires a compiled model artifact using either the Neuron compiler or Amazon SageMaker Neo. Once you have a compiled model for an Inferentia target and the associated container image URI, you can use SageMaker Inference Recommender to benchmark different Inferentia instance types.

SageMaker Model Monitor allows developers to detect and remediate concept drift. SageMaker Model Monitor automatically detects concept drift in deployed models and provides detailed alerts that help identify the source of the problem. All models trained in SageMaker AI automatically emit key metrics that can be collected and viewed in SageMaker Studio. From inside SageMaker Studio, you can configure data to be collected, how to view it, and when to receive alerts.

No. SageMaker AI operates the compute infrastructure on your behalf, allowing it to perform health checks, apply security patches, and do other routine maintenance. You can also deploy the model artifacts from training with custom inference code in your own hosting environment.

SageMaker AI hosting automatically scales to the performance needed for your application using Application Auto Scaling. In addition, you can manually change the instance number and type without incurring downtime by modifying the endpoint configuration.

SageMaker AI emits performance metrics to Amazon CloudWatch Metrics so you can track metrics, set alarms, and automatically react to changes in production traffic. In addition, SageMaker AI writes logs to Amazon CloudWatch Logs to let you monitor and troubleshoot your production environment.

SageMaker AI can host any model that adheres to the documented specification for inference Docker images. This includes models created from SageMaker AI model artifacts and inference code.

SageMaker AI is designed to scale to a large number of transactions per second. The precise number varies based on the deployed model and the number and type of instances to which the model is deployed.

As a fully managed service, Amazon SageMaker AI takes care of setting up and managing instances, software version compatibilities, and patching versions. It also provides built-in metrics and logs for endpoints that you can use to monitor and receive alerts. With SageMaker AI tools and guided workflows, the entire ML model packaging and deployment process is simplified, making it easy to optimize the endpoints to achieve desired performance and save costs. You can easily deploy your ML models including foundation models with just a few clicks within SageMaker Studio or using the new PySDK.

Batch Transform enables you to run predictions on large or small batch data. There is no need to break down the dataset into multiple chunks or manage real-time endpoints. With a simple API, you can request predictions for a large number of data records and transform the data quickly and easily.

SageMaker AI supports the following endpoint options: Single-model endpoints - One model on a container hosted on dedicated instances or serverless for low latency and high throughput. Multi-model endpoints - Host multiple models using shared infrastructure for cost-effectiveness and maximize utilization. You can control how much compute and memory each model can use to make sure each model has access to the resources it needs to run efficiently. Serial inference pipelines - Multiple containers sharing dedicated instances and executing in a sequence. You can use an inference pipeline to combine preprocessing, predictions, and post-processing data science tasks.

SageMaker Edge Manager makes it easier to optimize, secure, monitor, and maintain ML models on fleets of edge devices such as smart cameras, robots, personal computers, and mobile devices. SageMaker Edge Manager helps ML developers operate ML models on a variety of edge devices at scale.

To get started with SageMaker Edge Manager, you need to compile and package your trained ML models in the cloud, register your devices, and prepare your devices with the SageMaker Edge Manager SDK. To prepare your model for deployment, SageMaker Edge Manager uses SageMaker Neo to compile your model for your target edge hardware. Once a model is compiled, SageMaker Edge Manager signs the model with an AWS generated key, then packages the model with its runtime and your necessary credentials to get it ready for deployment. On the device side, you register your device with SageMaker Edge Manager, download the SageMaker Edge Manager SDK, and then follow the instructions to install the SageMaker Edge Manager agent on your devices. The tutorial notebook provides a step-by-step example of how you can prepare the models and connect your models on edge devices with SageMaker Edge Manager.

SageMaker Edge Manager supports common CPU (ARM, x86) and GPU (ARM, Nvidia) based devices with Linux and Windows operating systems. Over time, SageMaker Edge Manager will expand to support more embedded processors and mobile platforms that are also supported by SageMaker Neo.

No, you do not. You can train your models elsewhere or use a pre-trained model from open source or from your model vendor.

Yes, you do. SageMaker Neo converts and compiles your models into an executable that you can then package and deploy on your edge devices. Once the model package is deployed, the SageMaker Edge Manager agent will unpack the model package and run the model on the device.

SageMaker Edge Manager stores the model package in your specified Amazon S3 bucket. You can use the over-the-air (OTA) deployment feature provided by AWS IoT Greengrass or any other deployment mechanism of your choice to deploy the model package from your S3 bucket to the devices.

Neo dlr is an open-source runtime that only runs models compiled by the SageMaker Neo service. Compared to the open source dlr, the SageMaker Edge Manager SDK includes an enterprise grade on-device agent with additional security, model management, and model serving features. The SageMaker Edge Manager SDK is suitable for production deployment at scale.

SageMaker Edge Manager and AWS IoT Greengrass can work together in your IoT solution. Once your ML model is packaged with SageMaker Edge Manager, you can use the AWS IoT Greengrass OTA update feature to deploy the model package to your device. AWS IoT Greengrass allows you to monitor your IoT devices remotely, while SageMaker Edge Manager helps you monitor and maintain the ML models on the devices.

AWS offers the most breadth and depth of capabilities for running models on edge devices. We have services to support a wide range of use cases, including computer vision, voice recognition, and predictive maintenance.

For companies looking to run computer vision on edge devices such as cameras and appliances, you can use AWS Panorama. AWS Panorama offers ready-to-deploy computer vision applications for edge devices. It’s easy to get started with AWS Panorama by logging into the cloud console, specifying the model you would like to use in Amazon S3 or in SageMaker AI, and then writing business logic as a Python script. AWS Panorama compiles the model for the target device and creates an application package so it can be deployed to your devices with just a few clicks. In addition, independent software vendors who want to build their own custom applications can use the AWS Panorama SDK, and device manufacturers can use the Device SDK to certify their devices for AWS Panorama.

Customers who want to build their own models and have more granular control over model features can use SageMaker Edge Manager. SageMaker Edge Manager is a managed service to prepare, run, monitor, and update ML models across fleets of edge devices such as smart cameras, smart speakers, and robots for any use case such as natural langue processing, fraud detection, and predictive maintenance. SageMaker Edge Manager is for ML edge developers who want control over their model, including engineering different model features and monitoring models for drift. Any ML edge developer can use SageMaker Edge Manager through the SageMaker AI console and the SageMaker AI APIs. SageMaker Edge Manager brings the capabilities of SageMaker AI to build, train, and deploy models in the cloud to edge devices.

SageMaker Edge Manager is available in six Regions: US East (N. Virginia), US East (Ohio), US West (Oregon), EU (Ireland), EU (Frankfurt), and Asia Pacific (Tokyo). For details, see the AWS Regional Services list .

SageMaker Neo enables ML models to train once and run anywhere in the cloud and at the edge. SageMaker Neo automatically optimizes models built with popular DL frameworks that can be used to deploy on multiple hardware platforms. Optimized models run up to 25 times faster and consume less than a tenth of the resources of typical ML models.

To get started with SageMaker Neo, sign in to the SageMaker AI console, choose a trained model, follow the example to compile models, and deploy the resulting model onto your target hardware platform.

SageMaker Neo contains two major components: a compiler and a runtime. First, the SageMaker Neo compiler reads models exported by different frameworks. It then converts the framework-specific functions and operations into a framework-agnostic intermediate representation. Next, it performs a series of optimizations. Then, the compiler generates binary code for the optimized operations and writes them to a shared object library. The compiler also saves the model definition and parameters into separate files. During execution, the SageMaker Neo runtime loads the artifacts generated by the compiler—model definition, parameters, and the shared object library to run the model.

No. You can train models elsewhere and use SageMaker Neo to optimize them for SageMaker ML instances or AWS IoT Greengrass supported devices.

Currently, SageMaker Neo supports the most popular DL models that power computer vision applications and the most popular decision tree models used in SageMaker AI today. SageMaker Neo optimizes the performance of AlexNet, ResNet, VGG, Inception, MobileNet, SqueezeNet, and DenseNet models trained in MXNet and TensorFlow, and classification and random cut forest models trained in XGBoost.

You can find the lists of supported cloud instances , edge devices , and framework versions in the SageMaker Neo documentation.
