About LangChain
LangChain is a fundamental open-source orchestration framework (Python/JS) for building complex LLM applications. It abstracts away the massive complexity of interacting with various model APIs, vector stores, and external tools. It enables developers to construct dynamic 'Chains' and autonomous 'Agents'—allowing an LLM to browse the web, execute python code, query a database, and synthesize an answer iteratively.
