Perplexity LangChain Integration

langchain-perplexity is an official LangChain integration package that connects Perplexity AI's powerful conversational models and search capabilities with the LangChain framework. It allows developers to build LLM applications with real-time web search, streaming, and advanced search controls using Perplexity's API. The library is actively maintained as part of the LangChain ecosystem, with current version 1.1.0, and typically follows the release cadence of other LangChain partner packages.
