RubyLLM: A single, beautiful Ruby framework for all major AI providers

RubyLLM is a unified Ruby framework that provides a single, consistent interface for integrating multiple AI providers (OpenAI, Claude, Gemini, Ollama, and others) without dealing with their individual APIs and formats. It enables developers to quickly build chatbots, AI agents, and RAG applications with features including vision, audio transcription, image generation, embeddings, tool integration, and structured output, while requiring only three core dependencies. The framework includes Rails integration with a pre-built chat UI and supports over 800 models with automatic capability detection.
