接下来,使用提供的Python脚本创建一个项目,确保您的AWS区域配置正确,并且您的Amazon Bedrock API密钥已设置为OPENAI_API_KEY环境变量。

import os
import requests

# Configuration
BASE_URL = "https://bedrock-mantle.<YOUR-REGION-HERE>.api.aws/v1"
API_KEY  = os.environ.get("OPENAI_API_KEY")  # Your Amazon Bedrock API key

def create_project(name: str, tags: dict) -> dict:
    """Create a Bedrock project with cost allocation tags."""
    response = requests.post(
        f"{BASE_URL}/organization/projects",
        headers={
            "Authorization": f"Bearer {API_KEY}",
            "Content-Type": "application/json"
        },
        json={"name": name, "tags": tags}
    )

    if response.status_code != 200:
        raise Exception(
            f"Failed to create project: {response.status_code} - {response.text}"
        )

    return response.json()

# Example: Create a production project with full tag taxonomy
project = create_project(
    name="CustomerChatbot-Prod",
    tags={
        "Application": "CustomerChatbot",
        "Environment": "Production",
        "Team":        "CustomerExperience",
        "CostCenter":  "CC-1001",
        "Owner":       "alice"
    }
)
print(f"Created project: {project['id']}")

此脚本将返回项目详细信息,包括其唯一的id(例如,proj_123)和ARN。保存此id,因为它对于关联您的推理请求至关重要。每个AWS账户最多可以创建1,000个项目,即使对于最大的组织也提供了充足的灵igence。

关联推理请求

创建项目后,将其ID集成到您的Bedrock API调用中。例如,使用Responses API:

from openai import OpenAI

client = OpenAI(
    base_url="https://bedrock-mantle.<YOUR-REGION-HERE>.api.aws/v1",
    project="<YOUR-PROJECT-ID>", # ID returned when you created the project
)
response = client.responses.create(
    model="openai.gpt-oss-120b",
    input="Summarize the key findings from our Q4 earnings report."
)
print(response.output_text)

通过始终包含project参数,您可以确保每次推理的成本归因都准确无误。对于更高级的Bedrock应用程序,请考虑这如何与更广泛的策略集成,例如使用Amazon Bedrock构建AI驱动的A/B测试引擎

在AWS中激活和分析您的AI成本

实现全面成本可见性的最后一步是在AWS Billing控制台中激活您的自定义项目标签作为成本分配标签。这是一次性配置,它会指示AWS将这些标签纳入您的详细账单报告中。

激活成本分配标签

导航到AWS Billing and Cost Management控制台,并按照说明激活您的自定义标签。建议在创建第一个项目后立即执行此操作,以避免成本数据出现任何空白。请注意,这些标签可能需要长达24小时才能完全传播并在AWS Cost Explorer和AWS Data Exports中显示。

在AWS Cost Explorer中查看项目成本

激活后,您可以利用AWS Cost Explorer以前所未有的详细程度可视化和分析您的Amazon Bedrock支出。您可以按Service(Amazon Bedrock)筛选您的成本,然后按您的自定义成本分配标签(例如ApplicationEnvironmentCostCenter)进行分组。这使您能够:

  • 识别成本驱动因素: 快速查明哪些应用程序或环境消耗了最多的生成式AI资源。
  • 执行费用分摊: 为内部费用分摊模型生成准确的报告,确保部门为其AI使用量公平付费。
  • 优化支出: 检测效率低下的领域,例如在非关键开发环境中使用昂贵模型,并做出明智的决策以优化资源分配。
  • 预测和预算: 通过分析按特定工作负载细分的历史数据,提高未来AI支出预测的准确性。

通过采用Amazon Bedrock项目和严格的标签策略,组织可以将模糊的AI开销转化为透明、可操作的洞察。这不仅支持更好的财务治理,还培养了成本意识文化,使团队能够负责任且有效地扩展其生成式AI计划。这种对资源的详细控制也是高效集成Amazon Bedrock AgentCore等新功能的关键。

常见问题

What are Amazon Bedrock Projects and how do they enhance AI cost management?
Amazon Bedrock Projects provide a logical boundary within the Amazon Bedrock service to represent specific AI workloads, such as applications, environments, or experiments. By associating inference requests with a project ID and attaching resource tags, organizations can gain granular visibility into their generative AI spending. This allows for precise cost attribution to individual teams, departments, or applications, facilitating accurate chargebacks, identifying cost spikes, and informing strategic optimization decisions, thereby enhancing overall financial governance and resource allocation for large-scale AI deployments.
Why is a robust tagging strategy crucial for effective cost attribution with Bedrock Projects?
A robust tagging strategy is crucial because the tags attached to Amazon Bedrock Projects become the primary dimensions for filtering and grouping cost data in AWS Cost Explorer and AWS Data Exports. By systematically tagging projects with attributes like 'Application,' 'Environment,' 'Team,' and 'CostCenter,' organizations can create a comprehensive taxonomy that mirrors their internal structure. This structured approach enables deep dives into spending patterns, helps identify high-cost areas, supports cross-departmental chargebacks, and ensures that financial reporting accurately reflects resource consumption by specific AI workloads, making cost analysis more actionable and transparent.
How do I activate cost allocation tags for Amazon Bedrock Projects in AWS Billing?
After defining your tagging strategy and creating projects with associated tags in Amazon Bedrock, you must activate these tags as cost allocation tags within the AWS Billing and Cost Management console. This crucial, one-time setup step ensures that the tags attached to your Bedrock Projects are recognized by the AWS billing pipeline. Once activated, it can take up to 24 hours for the tags to propagate and for cost data to become visible and filterable in tools like AWS Cost Explorer and AWS Data Exports. Activating these tags promptly after your initial project setup prevents gaps in your cost visibility and ensures continuous, accurate reporting.
Which Amazon Bedrock APIs support cost attribution through Project IDs?
Currently, Amazon Bedrock Projects support cost attribution via Project IDs for inference requests made through the OpenAI-compatible APIs, specifically the Responses API and the Chat Completions API. When making API calls using these endpoints, developers should include the designated Project ID to ensure that the associated costs are accurately attributed to the correct workload. It is a best practice to always explicitly specify a Project ID in API calls to avoid costs being automatically associated with the default project in your AWS account, which can hinder granular cost analysis and management efforts.
What are the benefits of using Amazon Bedrock Projects for large enterprises?
For large enterprises, Amazon Bedrock Projects offer significant benefits by providing a standardized, scalable mechanism for managing and optimizing generative AI costs. They enable granular visibility into AI spending across diverse teams, applications, and environments, supporting precise financial forecasting and budgeting. This capability is vital for complex organizational structures requiring chargebacks or detailed departmental cost allocation. Furthermore, it empowers businesses to identify inefficient workloads, optimize model usage, and make data-driven decisions to reduce overall AI infrastructure expenses, aligning technology investments with business value and ensuring responsible AI scaling.
