Store activerecord models in vector stores and query them with LLMs!
llm-graph is a Ruby gem that provides verioned llm conversation graphs. It supports both directed and undirected graphs, and includes methods for adding and removing nodes and edges, checking for the existence of nodes and edges, and other common graph operations.
A Ruby on Rails gem that detects and sanitizes prompt injection attacks. Protects against direct injection (users hacking your LLMs via form inputs) and indirect injection (malicious prompts stored for other LLMs to scrape).
The Ruby library, Documentrix, is designed to provide a way to build and query vector databases for applications in natural language processing (NLP) and large language models (LLMs). It allows users to store and retrieve dense vector embeddings for text strings.
