Langchain simplifies development by allowing tasks to be ‘chained’ together, integrating with major LLM interfaces and APIs for designing intelligent systems.
Langgraph adds functionalities to build efficient AI workflows, focusing on state management and type validation for control granularity.
With Langgraph, building the graph involves defining nodes and edges with Python functions, enabling human-in-the-loop interactions and tool binding.
The workflow involves parsing user prompts, calling tools in the right sequence for reasoning, decision-making, and knowledge graph creation pushed to Neo4J using Langgraph.
