Understanding Amazon Bedrock model lifecycle

Summary

Amazon Bedrock regularly updates its foundation models (FMs), necessitating a clear understanding of their lifecycle for effective AI application management. Models transition through three states: Active, Legacy, and End-of-Life (EOL). Active models receive ongoing maintenance, while Legacy models provide at least 6 months' notice before EOL, allowing existing customers to continue usage, though new access may be restricted. For models with EOL dates after February 1, 2026, a Public extended access period of at least 3 months follows the initial Legacy phase, during which pricing may adjust. EOL models become inaccessible, requiring proactive migration. Amazon Bedrock ensures models are available for at least 12 months post-launch and remain in Legacy for at least 6 months before EOL, with notifications sent via email, AWS Health Dashboard, console alerts, and API.

Key takeaway

For AI Engineers and MLOps teams building on Amazon Bedrock, understanding and actively managing the foundation model lifecycle is critical. You should initiate migration planning as soon as a model enters the "Legacy" state, leveraging the extended access period for comprehensive testing and prompt optimization. Ensure your AWS account contacts are updated to receive timely notifications, and always validate service quotas for new models to prevent disruptions.

Key insights

Proactive management of Amazon Bedrock's FM lifecycle is crucial for maintaining AI application continuity and leveraging updated capabilities.

Principles

• Plan migrations immediately upon Legacy state notification.
• Thoroughly test new models before full deployment.
• Maintain rollback capabilities during transitions.

Method

The model lifecycle progresses from Active to Legacy (with an optional Public extended access period for models EOL after Feb 1, 2026) and finally to End-of-Life, requiring manual application code updates for migration.

In practice

• Update application code to new model IDs.
• Adjust prompts for new model specifications.
• Utilize side-by-side or shadow testing for comparison.
