llmrb/llm.rb: Zero-Dependency Ruby AI Runtime With Multi-Provider Support

GitHub·low signal

Ruby's most capable AI runtime ships as a zero-dependency toolkit supporting OpenAI, Gemini, Anthropic, DeepSeek, Ollama, and LlamaCpp with full support for chat, streaming, tool calling, audio, images, and files. Includes built-in ActiveRecord (acts_as_llm, acts_as_agent) and Sequel support. Designed for engineers who want control over long-lived, stateful AI workflows in Ruby — not a Rails wrapper but a runtime that happens to work with Rails. Fills a notable gap in the Ruby ecosystem.
