LangChain#\\nLangChain is a framework for developing applications powered by language models. We believe that the most powerful and differentiated applications will not only call out to a language model via an API, but will also:\\n\\nBe data-aware: connect a language model to other sources of data\\nBe agentic: allow a language model to interact with its environment\\n\\nThe LangChain framework is designed with the above principles in mind.\\nThis is the Python specific portion of the documentation. For a purely conceptual guide to LangChain, see here. For the JavaScript documentation, see here.\\n\\nGetting Started#\\nCheckout the below guide for a walkthrough of how to get started using LangChain to create an Language Model application.\\n\\nGetting Started Documentation\\n\\n\\n\\n\\n\\nModules#\\nThere are several main modules that LangChain provides support for.\\nFor each module we provide some examples to get started, how-to guides, reference docs, and conceptual guides.\\nThese modules are, in increasing order of complexity:\\n\\nModels: The various model types and model integrations LangChain supports.\\nPrompts: This includes prompt management, prompt optimization, and prompt serialization.\\nMemory: Memory is the concept of persisting state between calls of a chain/agent. LangChain provides a standard interface for memory, a collection of memory implementations, and examples of chains/agents that use memory.\\nIndexes: Language models are often more powerful when combined with your own text data - this module covers best practices for doing exactly that.\\nChains: Chains go beyond just a single LLM call, and are sequences of calls (whether to an LLM or a different utility). LangChain provides a standard interface for chains, lots of integrations with other tools, and end-to-end chains for common applications.\\nAgents: Agents 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 agents, a selection of agents to choose from, and examples of end to end agents.\\n\\n\\n\\n\\n\\nUse Cases#\\nThe above modules can be used in a variety of ways. LangChain also provides guidance and assistance in this. Below are some of the common use cases LangChain supports.\\n\\nPersonal Assistants: The main LangChain use case. Personal assistants need to take actions, remember interactions, and have knowledge about your data.\\nQuestion Answering: The second big LangChain use case. Answering questions over specific documents, only utilizing the information in those documents to construct an answer.\\nChatbots: Since language models are good at producing text, that makes them ideal for creating chatbots.\\nQuerying Tabular Data: If you want to understand how to use LLMs to query data that is stored in a tabular format (csvs, SQL, dataframes, etc) you should read this page.\\nInteracting with APIs: Enabling LLMs to interact with APIs is extremely powerful in order to give them more up-to-date information and allow them to take actions.\\nExtraction: Extract structured information from text.\\nSummarization: Summarizing longer documents into shorter, more condensed chunks of information. A type of Data Augmented Generation.\\nEvaluation: Generative models are notoriously hard to evaluate with traditional metrics. One new way of evaluating them is using language models themselves to do the evaluation. LangChain provides some prompts/chains for assisting in this.\\n\\n\\n\\n\\n\\nReference Docs#\\nAll of LangChain’s reference documentation, in one place. Full documentation on all methods, classes, installation methods, and integration setups for LangChain.\\n\\nReference Documentation\\n\\n\\n\\n\\n\\nLangChain Ecosystem#\\nGuides for how other companies/products can be used with LangChain\\n\\nLangChain Ecosystem\\n\\n\\n\\n\\n\\nAdditional Resources#\\nAdditional collection of resources we think may be useful as you develop your application!\\n\\nLangChainHub: The LangChainHub is a place to share and explore other prompts, chains, and agents.\\nGlossary: A glossary of all related terms, papers, methods, etc. Whether implemented in LangChain or not!\\nGallery: A collection of our favorite projects that use LangChain. Useful for finding inspiration or seeing how things were done in other applications.\\nDeployments: A collection of instructions, code snippets, and template repositories for deploying LangChain apps.\\nTracing: A guide on using tracing in LangChain to visualize the execution of chains and agents.\\nModel Laboratory: Experimenting with different prompts, models, and chains is a big part of developing the best possible application. The ModelLaboratory makes it easy to do so.\\nDiscord: Join us on our Discord to discuss all things LangChain!\\nProduction Support: As you move your LangChains into production, we’d love to offer more comprehensive support.
