A model offered on Amazon Bedrock can exist in one of three states: Active, Legacy, or End-of-Life (EOL). Their current status is visible both on the Amazon Bedrock console and in API responses. For example, when you make a GetFoundationModel or ListFoundationModels call, the state of the model will be shown in the modelLifecycle field in the response.

After a model launches on Amazon Bedrock, it remains available for at least 12 months after launch and stays in Legacy state for at least 6 months before EOL. This timeline helps customers plan migrations without rushing.

During the extended access period, pricing may be adjusted by the model provider. If pricing changes are planned, you will be notified in the initial legacy announcement and before any subsequent changes take effect, so there will be no surprise retroactive price increases. Customers with existing private pricing agreements with model providers or those using provisioned throughput will continue to operate under their current pricing terms during the extended access period. This makes sure customers who have made specific arrangements with model providers or invested in provisioned capacity will not be unexpectedly affected by any pricing changes.

Customers will receive a notification 6 months prior to a model’s EOL date when the model provider transitions a model to Legacy state. This proactive communication approach ensures that customers have sufficient time to plan and execute their migration strategies before a model becomes EOL. Notifications include details about the model being deprecated, important dates, extended access availability, and when the model will be EOL. AWS uses multiple channels to ensure these important communications reach the right people, including:
