Grok 4.7 上线 Amazon Bedrock
原标题：Grok 4.7 is now available on Amazon Bedrock
AI 摘要
xAI 的 Grok 4.7 现已在 Amazon Bedrock 上线，该模型面向编程、长时运行智能体和知识工作，支持 500K token 上下文窗口和四档可配置推理强度。据 xAI 称，其采用更大基座模型和更长强化学习训练，自我验证能力增强，Artificial Analysis 独立评测显示智能指数从 44 升至 46、编程智能体指数从 47 升至 56，但每任务输出 token 约翻倍。模型通过跨区域推理配置在 bedrock-runtime 上提供，兼容 Responses、Chat Completions 和 Converse API。

Grok 4.7 is now available on Amazon Bedrock xAI’s Grok 4.7 is now available on Amazon Bedrock, adding a frontier model built for coding, long-running agents, and knowledge work to the Bedrock model catalog. It offers a 500K token context window and supports configurable reasoning effort at four levels: low, medium, high, and xhigh. Grok 4.7 is served on the bedrock-runtime endpoint through cross-Region inference profiles, and it supports the Responses, Chat Completions, and Converse APIs. Accord
