llm.rb is an advanced runtime for building agentic AI applications on CRuby. It has zero runtime dependencies by default, it supports concurrent and parallel tool execution and has a single coherent API that spans 13+ providers. Streaming, tools, guards, compaction, the REPL, builtin MCP/A2A support and the database integrations all build on the same three concepts: providers, contexts, and agents.
