## 服务等级
<a name="model-card-openai-gpt-oss-20b-tiers"></a>

Amazon Bedrock 提供多个服务等级以满足您的工作负载要求。**Standard ** 提供按代币付费的访问权限，无需承诺（设置`"service_tier": "default"`或省略该字段）。****Priority 以溢价（套装`"service_tier": "priority"`）提供最快的响应时间。**Flex ** 为灵活、非时间敏感的工作负载（套装）提供更低成本的访问权限。`"service_tier": "flex"`**预留**为可预测的工作负载提供专用吞吐量和期限承诺；它是在账户级别设置的，而不是根据每个请求设置的（请联系您的 AWS 账户团队来启用）。有关更多信息，请参阅[服务等级](bedrock/latest/userguide/service-tiers-inference.html)。


| **Standard** | **优先级** | **Flex ** | **已保留 ** |
