Subscribing to a new Bedrock Model

In order to utilize new Bedrock Models in our AWS account, we are often required to ‘subscribe’ to the model to enable it. This is a one-time step that must be done for each model ID used by the system.

Prerequisite: Set up the aws CLI with the Developer-325565585839 profile (using the Developer role on the production account 325565585839) as described in Developer Bootstrap

To get an offer token for the model, run the following:

AWS_PROFILE=Developer-325565585839 aws bedrock list-foundation-model-agreement-offers --model-id us.anthropic.claude-sonnet-4-6

Once you have the offer token, you can complete the subscription:

AWS_PROFILE=Developer-325565585839 aws bedrock create-foundation-model-agreement \
--model-id us.anthropic.claude-sonnet-4-6 \
--offer-token <token_goes_here>
