Model lifecycle

Amazon Bedrock is continuously working to bring the latest versions of foundation models that have better capabilities, accuracy, and safety. As we launch new model versions, you can test them with the Amazon Bedrock console or API, and migrate your applications to benefit from the latest model versions.

A model offered on Amazon Bedrock can be in one of these states: Active, Legacy, or End-of-Life (EOL). You can see the status of offered models in the console and in the tables below. Additionally, when you make a GetFoundationModel or ListFoundationModels call, the state of the model will be shown in the modelLifecycle field in the response. Once a model launches on Amazon Bedrock, it will remain on Amazon Bedrock for at least 12 months before the EOL date.

Legacy versions

We will notify you when a model provider moves a model to the Legacy state. A model will be in the Legacy state for at least 6 months before the EOL date. While you can continue to use a Legacy model during this period, you should plan to transition to an Active model before the EOL date. New customers can't use Legacy models and existing customers may lose access to Legacy models due to inactivity.

For models with EOL dates after February 1, 2026: After a minimum of 3 months in the Legacy state, a model will enter the public extended access portion of the Legacy period. During this public extended access period, active users of a Legacy model can continue to use it until the EOL date (for a minimum of 3 months), but you should expect higher pricing, which will be set by the model provider. When the model first enters the Legacy state, we will notify you of the provider’s chosen date to transition a model to public extended access (which will be at least 3 months from notification) and pricing changes (if any). We will also notify you before any further pricing changes during the public extended access period.

You can't create a new Provisioned Throughput for models in the Legacy state.

The following table shows the legacy versions of models available on Amazon Bedrock. The Public extended access date column only applies to models with EOL dates later than February 1, 2026.

End-of-Life (EOL) versions

EOL — After the EOL date, a model will be marked EOL in the console and in the following table. On, or soon after the EOL date, the model is no longer available for use in all AWS Regions and requests made to this version will fail, unless there is a private arrangement between you and the provider for continued access. You will need to migrate to the latest model by updating your application code before the EOL date. Migration will not happen automatically.

The following table shows the versions of models that have passed the EOL date on Amazon Bedrock.

Customized models

If you have customized a model on Amazon Bedrock and use Provisioned Throughput by Model Units, we will support this Provisioned Throughput by Model Units for 12 months after the EOL date of the base model, provided the Model Units were provisioned prior to the legacy date. Once the model transitions to legacy state, you will not be able to create a new Provisioned Throughput by Model Units.
