I'm trying to invoke Claude Opus 4.8 through Amazon Bedrock in us-east-1, but both the CLI and Bedrock Playground return an AccessDeniedException saying the model isn't available for my account. The get-foundation-model-availability response reports agreementAvailability, authorizationStatus, entitlementAvailability, and regionAvailability as AVAILABLE or AUTHORIZED. I also accepted the AWS Marketplace agreement, waited for its status to change from PENDING to AVAILABLE, received the confirmation email, and verified that a valid payment method is configured. My account uses AWS Activate credits, although those credits work with Sonnet 4.6 and Haiku. Could this be a delay or synchronization problem between the Bedrock control plane and runtime service, an Activate-related restriction, or something else? Is there a workaround, or should I open an AWS Support case?

Other users have reported the same AccessDeniedException with several newer models, even without using credits. If the agreement and availability checks are all showing AVAILABLE, there may not be a local configuration change that fixes it. At that point, opening an AWS Support case with the model ID, region, account details, and agreement status is the most practical next step.
AWS Activate credits may be the issue. They don’t always apply consistently to Marketplace offerings or every model family, even when other Anthropic models work with the same account. Billing, Marketplace entitlements, and runtime permissions can get out of sync, so AWS Support may need to correct something on the backend.
That account is using AWS Activate credits, and the credits currently work with Sonnet 4.6 and Haiku, so the restriction may be specific to this model or model family.
