AWS Step Functions 新增由 AgentCore 提供支持的智能体推理步骤
Amazon Web Services · 2026-06-04 · via Recent Announcements

AWS Step Functions 现已支持通过与 Amazon Bedrock AgentCore 中的托管 Harness(目前为预览版)的优化集成,将 AI 智能体推理步骤添加到工作流中。AWS Step Functions 是一项可视化工作流服务,可利用内置的错误处理、并行执行和人工审批步骤来编排 AWS 服务。AgentCore Harness 可让您通过配置来声明智能体,并在其中指定模型、工具和行为。AgentCore 提供了用于端到端运行智能体循环的托管环境。

利用此集成,您可以在工作流中自动执行推理任务,例如对文档进行分类或从非结构化表单中提取元素。您可以在单个工作流中的各个决策点并行或按顺序运行多个智能体,并在关键操作前添加人工审批步骤。工作流执行历史记录会显示智能体输入、输出、Token 使用量和持续时间,以及指向 Amazon CloudWatch 中智能体交互详细信息的链接,以便您能够跟踪和审计每个智能体决策。您可以重用现有 Harness,也可以直接从 Workflow Studio(Step Functions 可视化生成器)中创建新 Harness。借助每次调用时可覆盖的设置(例如模型、系统提示词和工具),您可以根据每个工作流上下文调整智能体,而无需重复配置。利用可在工作流执行中或跨工作流执行使用的会话 ID,可以跨调用保留智能体上下文。

此 Harness 集成已在提供 AgentCore Harness 预览版的以下 AWS 区域推出:美国东部(弗吉尼亚州北部)、美国西部(俄勒冈州)、欧洲地区(法兰克福)和亚太地区(悉尼)。标准 Step Functions 定价适用于工作流执行,不收取额外的集成费用,标准 Amazon Bedrock 和 AgentCore 定价适用于模型推理以及相关的 AgentCore 资源。

要了解有关向工作流添加智能体推理步骤的更多信息,请访问 AWS Step Functions 文档。
