Revolutionary Rust-based LLM agent framework focused on breakthrough performance, type safety, and composable AI pipelines for building cutting-edge production agents.
Rig is an open-source Rust library for building LLM-powered applications and AI agents with a focus on performance, type safety, and composability. For teams building high-performance agent systems where latency, memory safety, and reliability are critical, Rig provides a Rust-native alternative to Python-based frameworks like LangChain and CrewAI.
The framework provides high-level abstractions for LLM completion and embedding workflows through its provider-agnostic API. Rig supports OpenAI, Anthropic (Claude), Google Gemini, Cohere, and Perplexity as LLM providers, with a unified interface that makes switching between providers trivial. The library handles prompt engineering, context management, and response parsing with Rust's type system ensuring correctness at compile time.
