Root cause

Exceeding Amazon Bedrock's model-level service quotas: RPM (requests per minute), TPM (tokens per minute with upfront deduction of input + max_tokens, adjusted post-response; output × burndown rate e.g. 5x for Claude), TPD. Quotas shared across InvokeModel/Converse/Stream APIs; low defaults on new accounts (e.g. 1 RPM for Claude 3.5 Sonnet).
