LangChain

Use Couchbase for vector stores, document loading, LLM caching, semantic caching with search indexes, and chat history storage.

Get Started

LangChain overview & features

Install the Couchbase LangChain package to integrate Couchbase capabilities into your applications. This allows for efficient vector storage, document loading, and caching of prompts and responses for LLMs. Semantic caching supports similarity-based retrieval and requires a search index and embeddings. Additionally, Couchbase can store chat message history for session management. Refer to the documentation for setup, examples, and API guidance for seamless implementation.
