{"library":"langchain-classic","type":"library","category":null,"description":"LangChain Classic is a legacy Python package providing the original API for building applications with Large Language Models (LLMs) through composability. It represents the state of the `langchain` library prior to its major architectural refactor (pre-0.1.0/0.2.0, before v1.0), which split the project into `langchain-core`, `langchain-community`, and partner packages. This package is in maintenance mode for backward compatibility and does not receive new features; it is not recommended for new projects.","language":"python","status":"deprecated","version":"1.0.3","tags":["LLM","AI","Generative AI","NLP","Framework","Legacy"],"install":[{"cmd":"pip install langchain-classic","imports":["from langchain_classic.chains import LLMChain"]}],"homepage":"https://docs.langchain.com/","github":"https://github.com/langchain-ai/langchain","docs":"https://reference.langchain.com/python/langchain_classic/","changelog":"https://github.com/langchain-ai/langchain/releases?q=tag%3A%22langchain-classic%3D%3D1%22","pypi":"https://pypi.org/project/langchain-classic/","npm":null,"openapi_spec":null,"status_page":null,"smithery":null,"compatibility":{"summary":{"python_range":"3.10–3.9","success_rate":40,"avg_install_s":8.6,"avg_import_s":null,"wheel_type":"wheel"},"url":"https://checklist.day/v1/registry/langchain-classic/compatibility"},"provenance":{"verified_status":"passing","verified_at":"Tue Jun 30","last_verified":"Tue Jun 30","next_check":"Thu Jul 30","install_tag":"stale"}}
