README

PHP library to incorporate LLMs (Large Language Models) into your applications.

Warning
This project is unstable and under development

Origin

This project originates from a direct fork/clone of the llm-chain project. The foundational work by the authors is gratefully acknowledged and appreciated.

llm-unchained was created primarily because the process of adding features for real-world use cases using llm-chain was found to be significantly hampered by overly restrictive design constraints (architectural as well as code style). These choices consistently slowed development progress. llm-unchained seeks to provide a balance that allows developers (myself included) to prototype more quickly and to provide the needed functionality and integrations more rapidly and with less friction.

Requirements

• PHP 8.2 or higher

Installation

The recommended way to install llm-unchained is through composer:

composer require onemoreangle/llm-unchained

Examples

See examples folder to run example implementations using this library. Depending on the example you need to export different environment variables for API keys or deployment configurations or create a .env.local based on .env file.

Documentation

For documentation in addition to the examples, please consult the documentation of the original llm-chain for now, but be aware that the APIs, classes, and methods may differ from the original llm-chain project.

Note The examples within this repository should always be up to date with the current state of the codebase, so they are the best source of truth on how to use the library.

Contributing

Currently, this project is maintained by the author but collaborations are definitely welcome, so please feel free to open issues or pull requests.
