Notice: Amazon Augmented AI (A2I) has been closed to new customers since July 30, 2026 and is in maintenance mode. Existing customers can continue to use the service unchanged. According to the AWS documentation, AWS keeps investing in security and availability but does not plan to add new features.
What is Amazon Augmented AI (A2I)?
Amazon Augmented AI (A2I) is a fully managed service within Amazon SageMaker AI that provides human-in-the-loop workflows for machine learning. The service automatically detects ML predictions with low confidence scores and routes them to human reviewers for verification. This allows organizations to combine the speed of ML with the accuracy of human judgment.
A2I integrates seamlessly with Amazon Textract, Amazon Rekognition, and custom SageMaker models. The service manages the entire review workflow: from task creation and assignment to reviewers through to result consolidation. Private workforce teams, Amazon Mechanical Turk, or third-party vendors can serve as reviewers.
Core Features
- Automatic Routing Logic: Routes predictions to human reviewers automatically based on confidence scores
- Flexible Workforce Options: Supports private teams, Amazon Mechanical Turk, and third-party vendors
- Custom Task Templates: Create custom review interfaces for specific use cases
- Native Integrations: Direct integration with Textract, Rekognition, and SageMaker
- Audit Trail: Complete logging of all human decisions for compliance
Typical Use Cases
Document Processing: Textract extracts data from forms and invoices. For uncertain results, A2I automatically routes documents to reviewers who validate or correct the extracted values.
Content Moderation: Rekognition checks user-generated content for problematic material. Borderline cases with medium confidence are forwarded to a moderation team that makes the final decision.
Medical Image Analysis: ML models analyze medical images and flag anomalies. Specialists review the results and confirm or correct the automated analysis.
Benefits
- Combines ML speed with human accuracy
- Reduces errors in critical business decisions
- Scales flexibly with growing review volume
- Full traceability of all decisions
