## 以编程方式访问
<a name="model-card-anthropic-claude-mythos-preview-programmatic-access"></a>

使用以下模型 ID 和端点 URL 以编程方式访问此模型。有关可用 API 和终端节点的更多信息，请参阅支持[的 API ](bedrock/latest/userguide/apis.html) 和支持的[终端节点](bedrock/latest/userguide/endpoints.html)。


| **Endpoint** | **模特 ID ** | **In-Region 端点 URL ** | **地理推断 ID ** | **全局推理 ID ** | 
| --- | --- | --- | --- | --- | 
| bedrock-mantle | anthropic.claude-mythos-preview | https://bedrock-mantle.{region}.api.aws | N/A | N/A | 

*例如，如果区域为 us-east-1（弗吉尼亚北部），则基岩地堡终端节点 URL 将为 “”。https://bedrock-mantle.us-east-1.api.aws*

## 服务等级
<a name="model-card-anthropic-claude-mythos-preview-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 ** |

***区域可用性一览 * **

Amazon Bedrock 提供三种推理选项：将请求**In-Region**保留在单一区域内以确保严格合规；在尊重数据驻留的前提下跨地理区域（例如美国、欧盟和亚太地区）进行地理路由；在没有居住限制的情况下，**全球 Cross-Region**路由到全球任何地方。** Cross-Region **有关更多详细信息，请参阅该[按型号划分的区域可用性](models-region-compatibility.md)页面。

**第 1 步- AWS 账户：**如果您已经有 AWS 账户，请跳过此步骤。如果您是新手 AWS，请注册一个 A [ WS 账户](https://portal.aws.amazon.com/billing/signup)。

**第 2 步-API 密钥：**前往[亚马逊 Bedrock 控制台](https://console.aws.amazon.com/bedrock/home#/api-keys/long-term/create)并生成长期 API 密钥。

**第 3 步-获取 SDK：**要使用此入门指南，必须已安装 Python。然后安装相关的软件。

```
pip install -U "anthropic[bedrock]"
```

**第 4 步-设置环境变量：将您的环境**配置为使用 API 密钥进行身份验证。

```
AWS_BEARER_TOKEN_BEDROCK="<provide your Bedrock API key>"
```

**第 5 步-运行您的第一个推理请求：**将文件另存为 `bedrock-first-request.py`
