Amazon Bedrock: Claude Sonnet 5 returns AccessDenied while Amazon Nova Lite returns "Too many tokens per day" on a new workload

Question

Region:
- us-west-2

Account:
- Personal AWS account
- About 2 years old
- Basic Support plan

Verified:
- list-foundation-models returns anthropic.claude-sonnet-5
- get-foundation-model-availability:
  agreementAvailability = AVAILABLE
  authorizationStatus = AUTHORIZED
  entitlementAvailability = AVAILABLE
  regionAvailability = AVAILABLE

Observed behavior:
- Claude Sonnet 5:
  AccessDeniedException
  anthropic.claude-sonnet-5 is not available for this account.

- Amazon Nova Lite:
  ThrottlingException
  Too many tokens per day

The account has not previously used Amazon Bedrock for inference.

Is this likely to be an account entitlement/quota issue, or is there another configuration I should verify?

Hello.

Quotas may be set to low levels for new AWS accounts, accounts using Bedrock for the first time, or accounts with limited usage history.  
I encountered the same error as you when trying to run "claude-sonnet-5" on my personal AWS account.  
However, it ran successfully on my company's AWS account, which suggests that accounts with higher usage history may have higher quotas set.  
I recommend contacting AWS Support, as discussed in the re:Post thread below.
