The Reserved tier, launched in 2026, allows customers to reserve prioritized compute and tokens-per-minute for Anthropic Claude Opus 4.5 and Haiku 4.5 models. This supports workloads with asymmetric token usage patterns, such as summarization or content generation, by allocating input and output capacities flexibly to optimize performance and costs.
If reserved capacity is exceeded, the service automatically overflows to the Standard pay-as-you-go tier ensuring uninterrupted operation. Customers can reserve capacity for one or three months, billed monthly at fixed pricing, enhancing predictability for mission-critical AI applications across AWS regions.
