π Large language models are transformative and can enable developers to build powerful applications.
π Combining large language models with other sources of computation or knowledge can enhance their power.
π‘ Using LangChain enables the combination of multiple inferences, solving the problem of limited token length.
π Sequential chains in Weaviate execute links in a sequential order, using one output as the input for the next step.
π€ Example conversation between a bot and the speaker, demonstrating the use of sequential chains.
π The bot acts as a fact checker, improving its answer based on a given statement and making a list of assumptions and assertions.
π Elephants are mammals and do not lay eggs.
π₯ Eggs come in different sizes.
βοΈ Weaviate + LangChain uses techniques like stuffing, map reduce, refine, and map rebrink to overcome limitations of input token length.
π Weaviate and LangChain are used to process and analyze chunks of data.
𧩠Multiple prompts are combined to create a comprehensive answer.
π The large language model refines its output using local memory and previous summaries.
π Mapri rank assigns scores to the answers based on certainty.
π§ Equipping language models with tools like Weaviate and LangChain to execute code and generate code.
π¬ Using Chat Vector DB to implement a Vector database and answering questions by rephrasing them as standalone questions.
π§ Addressing the hallucination problem by stating 'don't know' if the answer is not known.
π The video demonstrates how to use Weaviate and LangChain together to search for specific content.
π The speaker explains how to connect to the Weaviate instance and specify the class and property for LangChain to search.
π» The demonstration showcases the simplicity of the implementation with just a few lines of code.
π‘ Weaviate and LangChain were released in version 1.17.
π The combination of a large language model and a vector database allows Weaviate to provide contextually relevant information.
π Hybrid search, introduced in version 1.17, is explained and demonstrated.
