⚡ Building applications with LLMs through composability in PHP ⚡

The LangChain PHP Port is a meticulously crafted adaptation of the original LangChain library, bringing its robust natural language processing capabilities to the PHP ecosystem. This faithful port allows developers to harness the full potential of LangChain's features, while preserving the familiar PHP syntax and structure.

Installation

You can install the package via composer:

composer require kambo/langchain

🤔 What is this?

Large language models (LLMs) are emerging as a transformative technology, enabling developers to build applications that they previously could not. But using these LLMs in isolation is often not enough to create a truly powerful app - the real power comes when you can combine them with other sources of computation or knowledge.

This library is aimed at assisting in the development of those types of applications. Common examples of these types of applications include:
