What is langchain?

LangChain is an integrated framework for developing applications powered by large language models (LLMs), streamlining the process of building AI applications. It offers modular components such as chains for multi-step workflows, agents for dynamic decision-making, memory modules for context retention, and integrations with external data sources and tools. LangChain enables developers to create AI applications with contextual awareness and reasoning capabilities by connecting LLMs to real-world data and APIs. Combined with LangGraph for large-scale agent orchestration and LangSmith for monitoring and evaluation, LangChain supports the complete lifecycle of AI applications—from development through deployment and management—making it suitable for both startups and large enterprises.

Key Features of langchain?

Composable Workflow Chaining
