What is Amazon Augmented AI
Amazon Augmented AI (A2I) is a managed AWS service that adds human review workflows to machine learning predictions, commonly used to validate low-confidence inferences and generate labeled data. It targets teams building ML applications that need human-in-the-loop review for tasks such as document processing, content moderation, and custom model inference. The service integrates with AWS ML services and supports custom workflows using AWS components, with options to route tasks to internal reviewers or third-party workforces.
Native AWS service integration
A2I integrates directly with AWS services commonly used in ML pipelines, including Amazon SageMaker and AWS workflow/identity components. This reduces the amount of custom glue code needed when the rest of the stack already runs on AWS. It also aligns with AWS security and access control patterns for enterprise deployments.
Human review workflow orchestration
The product provides a structured way to route model outputs to human reviewers based on rules such as confidence thresholds. It supports review UIs and task management patterns needed for auditability and exception handling. This is useful when teams need consistent review processes rather than ad hoc labeling jobs.
Flexible workforce options
A2I supports multiple reviewer sources, including private work teams and external workforces through AWS-managed options. This helps organizations scale review capacity without building a separate vendor management layer into their ML system. It also allows different review pools for different data sensitivity levels.
Not a full labeling platform
A2I focuses on human-in-the-loop review and workflow routing rather than end-to-end dataset management. Capabilities often expected in dedicated annotation suites—such as rich dataset versioning, advanced QA analytics, and broad modality tooling—may require additional tools. Teams with heavy annotation operations may find it less comprehensive than specialized platforms.
AWS ecosystem dependency
The service is designed for AWS-native architectures and typically assumes use of AWS IAM, storage, and related services. Organizations running multi-cloud or on-prem ML stacks may face additional integration work. Vendor lock-in considerations can be material for long-lived labeling and review pipelines.
Workflow setup can be complex
Implementing production-grade review flows can involve configuring multiple AWS components and defining task templates and routing logic. This can increase operational overhead compared with tools that provide more out-of-the-box project management and annotation UX. Costs can also become harder to predict when review volume fluctuates.
Plan & Pricing
Pricing model: Pay-as-you-go (charged per human-reviewed object)
Free tier / trial: AWS Free Tier — first year includes 500 human reviews total (approx. 42 objects/month). The AWS page also notes new-customer Free Tier credits (up to $200) and a free plan option at sign-up (details on AWS Free Tier page).
Example costs (from AWS official pricing page):
- Amazon Rekognition workflow (internal employees): $0.03 per image for the first 100,000 human-reviewed images; $0.02 per image for the next 50,000.
- Amazon Textract workflow (internal employees): $0.03 per page for the first 100,000 human-reviewed pages; $0.02 per page for the next 100,000.
- Amazon Mechanical Turk (example reviewer payments): reviewer payment example $0.012 per page per reviewer (example showing 3 reviewers → $0.036 additional per human-reviewed page to pay reviewers).
Workforce / vendor pricing: If using AWS Marketplace vendors or Amazon Mechanical Turk, additional per-review charges apply (vendor-set pricing). If using your own employees as reviewers, there is no additional per-reviewed-object workforce charge.
Notes & links: Additional charges for the underlying services (e.g., Amazon Rekognition, Amazon Textract) apply separately; see each service's pricing page for those costs. All information sourced from the official AWS Amazon Augmented AI pricing page.
