llm.rb is a Ruby-centric toolkit for building real LLM-powered systems — where LLMs are part of your architecture, not just API calls. It gives you explicit control over contexts, tools, concurrency, and providers, so you can compose reliable, production-ready workflows without hidden abstractions. Built for engineers who want to understand and control their LLM systems. No frameworks, no hidden magic — just composable primitives for building real applications, from scripts to full systems like Relay. ## Key Features - **Contexts are central** — Hold history, tools, schema, usage, cost, persistence, and execution state - **Tool execution is explicit** — Run local, provider-native, and MCP tools sequentially or concurrently - **One API across providers** — Unified interface for OpenAI, Anthropic, Google, xAI, zAI, DeepSeek, Ollama, and LlamaCpp - **Thread-safe where it matters** — Providers are shareable, while contexts stay isolated and stateful - **Production-ready** — Cost tracking, observability, persistence, and performance tuning built in - **Stdlib-only by default** — Runs on Ruby standard library, with optional features loaded only when used ## Capabilities - Chat & Contexts with persistence - Streaming responses - Tool calling with JSON Schema validation - Concurrent execution (threads, fibers, async tasks) - Agents with auto-execution - Structured outputs - MCP (Model Context Protocol) support - Multimodal inputs (text, images, audio, documents) - Audio generation, transcription, translation - Image generation and editing - Files API for document processing - Embeddings and vector stores - Local model registry for capabilities, limits, and pricing
