📄 中文摘要
AWS 在 2025 年发布了 Strands Agents，这是一个开源 SDK，旨在简化构建智能代理的过程。与传统的 LangChain 和 LangGraph 相比，Strands 采用模型驱动的方法，用户只需提供一个模型、一个系统提示和一组工具，便可让 LLM 自行决定代理的逻辑。这种方法显著减少了代码量，使得构建智能代理变得更加高效和便捷。通过这种方式，开发者可以更专注于设计和优化代理的功能，而不必过多关注底层实现细节。
AWS Strands 用 3 行代码替代了 LangGraph 的 60 行。这是完整故事
📄 English Summary
AWS Strands Replaced 60 Lines of LangGraph With 3. Here’s the Full Story
AWS released Strands Agents in May 2025, an open-source SDK designed to simplify the process of building intelligent agents. Unlike traditional frameworks like LangChain and LangGraph, Strands adopts a model-driven approach where users only need to provide a model, a system prompt, and a list of tools, allowing the LLM to determine the agent's logic autonomously. This approach significantly reduces the amount of code required, making the development of intelligent agents more efficient and convenient. Developers can focus more on designing and optimizing the agent's functionalities rather than getting bogged down in implementation details.
