Examples include summarization of long pieces of text and question/answering over specific data sources.Īgents involve an LLM making decisions about which Actions to take, taking that Action, seeing an Observation, and repeating that until done. LangChain provides a standard interface for chains, lots of integrations with other tools, and end-to-end chains for common applications.ĭata Augmented Generation involves specific types of chains that first interact with an external data source to fetch data for use in the generation step. This includes prompt management, prompt optimization, a generic interface for all LLMs, and common utilities for working with LLMs.Ĭhains go beyond a single LLM call and involve sequences of calls (whether to an LLM or a different utility). These are, in increasing order of complexity: There are six main areas that LangChain is designed to help with. Resources (high-level explanation of core concepts).How-To examples (demos, integrations, helper functions).
Getting started (installation, setting up the environment, simple examples).Please see here for full documentation on: End-to-end Example: Question Answering over Notion Database.❓ Question Answering over specific documents Common examples of these applications include: This library aims to assist in the development of those types of applications. However, using these LLMs in isolation is often insufficient for creating a truly powerful app - the real power comes when you can combine them with other sources of computation or knowledge. Large language models (LLMs) are emerging as a transformative technology, enabling developers to build applications that they previously could not. Quick InstallĬonda install langchain -c conda-forge 🤔 What is this? Please fill out this form and we'll set up a dedicated support Slack channel. Production Support: As you move your LangChains into production, we'd love to offer more comprehensive support. Looking for the JS/TS version?
