Langchain

Langchain is an open-source software framework designed to simplify the development of applications powered by large language models (LLMs). The framework provides developers with standardized tools, abstractions, and interfaces for integrating LLMs into broader systems and workflows, reducing the complexity of common implementation patterns.

Core Functionality

The framework abstracts away low-level details of LLM interaction, allowing developers to focus on application-specific logic rather than infrastructure concerns. Langchain provides modular components for handling tasks such as prompt management, memory handling, document processing, and chaining multiple LLM calls together in structured sequences.

Use Cases

Langchain is used across various application domains including question-answering systems, document analysis, conversational interfaces, and multi-step reasoning tasks. Its flexibility allows it to work with multiple LLM providers and integrate with external data sources and tools.
