LangChain cookbook

Example code for building applications with LangChain, with an emphasis on more applied and end-to-end examples than contained in the main documentation.

Notebook	Description

Semi_structured_multi_modal_RA...	Perform retrieval-augmented generation (rag) on documents with semi-structured data and images, using various tools and methods such as unstructured for parsing, multi-vector retriever for storing, lcel for implementing chains, and open source language models like llama2, llava, and gpt4all.

causal_program_aided_language_...	Implement the causal program-aided language (cpal) chain, which improves upon the program-aided language (pal) by incorporating causal structure to prevent hallucination in language models, particularly when dealing with complex narratives and math problems with nested dependencies.
code-analysis-deeplake.ipynb	Analyze its own code base with the help of gpt and activeloop's deep lake.
custom_agent_with_plugin_retri...	Build a custom agent that can interact with ai plugins by retrieving tools and creating natural language wrappers around openapi endpoints.
custom_agent_with_plugin_retri...	Build a custom agent with plugin retrieval functionality, utilizing ai plugins from the plugnplai directory.
databricks_sql_db.ipynb	Connect to databricks runtimes and databricks sql.
deeplake_semantic_search_over_...	Perform semantic search and question-answering over a group chat using activeloop's deep lake with gpt4.

forward_looking_retrieval_augm...	Implement the forward-looking active retrieval augmented generation (flare) method, which generates answers to questions, identifies uncertain tokens, generates hypothetical questions based on these tokens, and retrieves relevant documents to continue generating the answer.
generative_agents_interactive_...	Implement a generative agent that simulates human behavior, based on a research paper, using a time-weighted memory object backed by a langchain retriever.
gymnasium_agent_simulation.ipynb	Create a simple agent-environment interaction loop in simulated environments like text-based games with gymnasium.
