Frequently Asked Questions

What is LangChain and why should I use it for LLM applications?

LangChain is the premier open-source framework for building applications powered by language models. It provides standardized abstractions for document loading, vector embeddings, prompt templates, agentic tool calling, and memory storage.

What is the difference between LangChain and LangGraph?

LangChain connects linear LLM chains and document chains. LangGraph extends LangChain with cyclic, stateful multi-agent workflows, enabling advanced reasoning loops, branching decisions, and human-in-the-loop approvals.

How do you optimize LangChain application latency and token costs?

We use streaming responses, semantic prompt caching (Redis / GPTCache), vector search reranking (Cohere), and route simple queries to smaller models (GPT-4o-mini).
