Combining LangChain and Weaviate

Large Language Models (LLMs) have transformed human interaction with computers by enabling them to understand and generate human-like language on a massive scale. However, LLMs face limitations such as hallucination and limited input lengths. LangChain is an emerging tool that helps overcome these limitations. Sequential chains enable combining multiple LLM inferences together, while CombineDocuments breaks down long inputs into manageable chunks for processing. Other techniques like Stuffing, Map Reduce, Refine, and Map Rerank help improve the efficiency of LLMs. Tool Use allows augmentation of language models to use tools such as vector databases, calculators, or code executors. The ChatVectorDB chain in LangChain enables building an LLM that stores chat history and retrieves context from Weaviate for generating responses. By integrating with Weaviate, developers can create powerful applications using these advanced LLM techniques.
