In January 2026, Amazon Bedrock expanded its Reserved tier to the Anthropic Claude Sonnet 4.5 model within AWS GovCloud (US-West). This tier allows customers to reserve dedicated compute capacity with configurable input and output token rates, matching specific workload requirements while controlling costs. Reserved capacity helps maintain consistent service levels for mission-critical applications with varied token usage patterns, such as summarization or content generation.
If demand exceeds reserved capacity, automatic overflow to the standard pay-as-you-go tier ensures service continuity without disruption. The Reserved tier is available for one- or three-month commitments, billing customers at fixed monthly rates per tokens-per-minute reserved. This service offers enhanced flexibility and cost management for deploying advanced AI models in regulated environments.
