LangServe System Requirements (CPU, RAM, Disk)

LangServe is an official LangChain tool that helps developers deploy LangChain runnables and chains as REST APIs. Built on FastAPI and pydantic, LangServe automatically generates API endpoints from any LangChain chain or runnable with minimal code. It features a built-in interactive playground UI for testing endpoints, automatic input/output schema generation, streaming support, and both Python and JavaScript client libraries for easy integration. Whether you are building a RAG pipeline, an agent workflow, or a simple LLM chain, LangServe turns it into a production-ready API endpoint instantly. Note: LangServe has been deprecated since Nov 2024 in favor of the LangGraph Platform, though it remains functional for existing deployments.
