Building Effective Agents with LangGraph

Anthropic's recent blog post on "Building Effective Agents" lays out the difference between "agents" and "workflows", and presents a number of common patterns for both. Here, we implement every workflow and agent pattern covered in the blog from scratch using LangGraph. We explain the key differences between workflows and agents, when to use each approach, and how to implement them effectively. We also cover the benefits you can gain from using LangGraph as a framework. Documentation: https://langchain-ai.github.io/langgr... Video notes: https://mirror-feeling-d80.notion.sit...
