在 Amazon Bedrock 上用 Grok 4.7 构建长时程智能体
原标题：Build long-horizon agents with Grok 4.7 on Amazon Bedrock
AI 摘要
AWS 博客介绍 SpaceXAI 的 Grok 4.7 已在 Amazon Bedrock 上线，支持可配置推理强度、工具调用和结构化输出，并提供跨区域推理配置文件。文章构建了一个工具调用智能体，在三个需要搜索而非简单查询的任务上测试了四种推理强度，共 72 次运行，正确 67 次；xhigh 全部正确，low 用约八分之一输出 token 达到 15/18 正确。文章还给出接入方式、IAM 权限、token 预算与生产监控建议。

Build long-horizon agents with Grok 4.7 on Amazon Bedrock SpaceXAI’s Grok 4.7 is now available on Amazon Bedrock, which offers a choice of foundation models (FMs) from multiple providers. According to SpaceXAI, Grok 4.7 is trained to work longer on more difficult tasks and knows when to check its own work. That matters most for agents, which carry a task through many steps and must verify what they find along the way. An agent that works this way has to do more than look things up. It has to for
