Can I enable GPT-5.4 on AWS without going through sales?

This may be a model-specific availability limit rather than a problem with your account. Reports suggest access can be restricted while capacity is limited, with priority given to predictable or larger workloads. Having a long-standing subscription does not necessarily unlock it automatically.

Check the model’s access details in the relevant AWS service and ask support whether your account or region is eligible. If the console directs you to sales, there may not be a manual switch you can flip.

Being able to use Claude does not guarantee access to every model. Treat each model as a separate availability check. Confirm the AWS region and service you are using, then check whether GPT-5.4 access is offered there. If it still points you to sales, ask them directly about eligibility and expected access, rather than assuming your account is misconfigured.

Short version: I would not count on enabling it yourself if the error explicitly sends you to sales. The discussion points to capacity or access controls, but does not establish a firm rule about spend or account age. A support request can clarify whether there is a specific setting to change or whether you need to wait for approval.
