LangGraph

LangGraph is a library for building stateful, multi-actor applications with LLMs. It extends the LangChain ecosystem by allowing developers to define cyclic workflows and agent loops using a graph representation (Nodes and Edges).

Key Features

• Cyclic Graphs: Unlike standard linear chains, LangGraph allows loops, essential for iterative refinement.
• State Management: Built-in persistence for conversation states and memory checkpoints.
• Human-in-the-Loop: Pause execution to wait for user approval or input.
