LangGraph

LangGraph is a specialized framework designed to build stateful, multi-actor applications with LLMs.

Key Capabilities

• Cyclic & Graph Workflows: Allows loops and conditional edges, making it ideal for ReAct loops, iterative refinement, and multi-agent debate.
• State Management: Uses central state schemas updated deterministically as execution moves across graph nodes.
• Human-in-the-Loop: Supports pausing execution for human approval or feedback before resuming node transitions.
• Time-Travel Debugging: Enables rewinding state to inspect or fork execution paths during agent testing.
