## 程式設計存取
<a name="model-card-anthropic-claude-mythos-preview-programmatic-access"></a>

使用以下模型 IDs和端點 URLs以程式設計方式存取此模型。如需可用 APIs和端點的詳細資訊，請參閱[支援的 APIs](bedrock/latest/userguide/apis.html)和[支援的端點](bedrock/latest/userguide/endpoints.html)。


| **端點** | **模型 ID** | **區域端點 URL** | **地理推論 ID** | **全域推論 ID** | 
| --- | --- | --- | --- | --- | 
| bedrock-mantle | anthropic.claude-mythos-preview | https://bedrock-mantle.{region}.api.aws | N/A | N/A | 

*例如，如果區域是 us-east-1 （維吉尼亞北部），則 bedrock-mantle 端點 URL 將為 "https://bedrock-mantle.us-east-1.api.aws"。*

## 服務層
<a name="model-card-anthropic-claude-mythos-preview-tiers"></a>

Amazon Bedrock 提供多種服務層，以符合您的工作負載需求。**Standard** 提供pay-per-token存取 （設定`"service_tier": "default"`或省略 欄位）。**Priority** 提供價格溢價最快的回應時間 （設定 `"service_tier": "priority"`)。**Flex** 為彈性、non-time-sensitive的工作負載提供較低成本的存取 （設定 `"service_tier": "flex"`)。**預留**會提供專用輸送量與可預測工作負載的期限承諾；它會在帳戶層級設定，而不是根據請求設定 （請聯絡您的 AWS 帳戶團隊啟用）。如需詳細資訊，請參閱 [服務方案](bedrock/latest/userguide/service-tiers-inference.html)。

## 範例程式碼
<a name="model-card-anthropic-claude-mythos-preview-sample-code"></a>

**步驟 1 - AWS 帳戶：**如果您已經有 AWS 帳戶，請略過此步驟。如果您是新手 AWS，請註冊 [AWS 帳戶](https://portal.aws.amazon.com/billing/signup)。

**步驟 2 - API 金鑰：**前往 [Amazon Bedrock 主控台](https://console.aws.amazon.com/bedrock/home#/api-keys/long-term/create)並產生長期 API 金鑰。

**步驟 3 - 取得 SDK：**若要使用此入門指南，您必須已安裝 Python。然後安裝相關的軟體。

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

**步驟 4 - 設定環境變數：**設定您的環境以使用 API 金鑰進行身分驗證。

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

**步驟 5 - 執行您的第一個推論請求：**將檔案儲存為 `bedrock-first-request.py`
