用于优化性能和成本的服务分层

Amazon Bedrock 为模型推断提供了四个服务等级：预留、优先级、标准和弹性。通过服务层，您可以针对可用性、成本和性能进行优化。

预留等级

Reserved 层允许您为无法容忍任何停机的任务关键型应用程序预留优先计算容量。您可以灵活地分配不同的输入和输出 tokens-per-minute容量，以满足工作负载的确切要求并控制成本。当您的应用程序需要的 tokens-per-minute容量超过您的预留容量时，该服务会自动溢出到标准层，从而确保不间断运行。预留层的目标是模型响应的正常运行时间为 99.5%。客户可以预留 1 个月或 3 个月的容量。客户按固定价格每 1K 支付 tokens-per-minute，按月计费。

要访问预留套餐，请联系您的 AWS 账户团队。

优先等级

优先级可提供最快的响应时间，而且价格高于标准按需定价。它最适合具有面向客户的业务工作流程且不保证全天候容量预留的关键任务应用程序。优先等级不需要事先预订。您只需将 “service_tier” 可选参数设置为 “优先级”，即可使用请求级别的优先级。优先级别请求的优先级高于标准和弹性级别的请求。

标准等级

标准层为内容生成、文本分析和例行文档处理等日常 AI 任务提供稳定的性能。默认情况下，当缺少 “service_tier” 参数时，所有推理请求都会路由到标准层。您也可以将 “service_tier” 可选参数设置为 “默认”，以便使用标准套餐处理您的推理请求。

弹性等级

对于可以处理更长处理时间的工作负载，Flex 层可提供经济实惠的处理能力，并享受定价折扣。这可以帮助您优化模型评估、内容摘要和代理工作流程等工作负载的成本。您可以将 “service_tier” 可选参数设置为 “flex”，这样您的推理请求将与 Flex 层一起提供，并享受定价折扣。

使用服务层功能

要访问服务层功能，您可以在调用 Amazon Bedrock 运行时 API 时将 “service_tier” 可选参数设置为 “预留”、“优先级”、“默认” 或 “弹性”。

"service_tier" : "reserved | priority | default | flex"

您的模型按需配额在 “优先级”、“默认” 和 “弹性” 服务层之间共享。您的 “预留” 套餐容量预留与按需配额是分开的。已处理请求的服务等级配置在 API 响应和 AWS CloudTrail 事件中可见。您还可以在、和 ModelId、 ServiceTier下的 Amazon Metrics 中查看服务等级 CloudWatch 指标 ResolvedServiceTier，其中 ResolvedServiceTier 显示了满足您请求的实际等级。

有关定价的更多信息，请访问定价页面。
