Revolutionary Hugging Face's lightweight Python library for building tool-calling AI agents with minimal code and maximum transparency.
smolagents is Hugging Face's minimalist agent framework designed to make building tool-calling AI agents as simple as possible. The library embraces a philosophy of radical simplicity — the core agent loop is just a few hundred lines of code, making it easy to understand, debug, and extend. Despite its small footprint, smolagents supports sophisticated agent patterns including multi-step reasoning, tool calling, code generation, and multi-agent orchestration.
The framework provides two main agent types: ToolCallingAgent, which uses the model's native function calling capabilities, and CodeAgent, which generates and executes Python code to accomplish tasks. CodeAgent is particularly powerful — instead of being limited to pre-defined tool interfaces, the agent can write arbitrary Python code that combines tools, processes data, and implements custom logic on the fly.
The industry-standard framework for building production-ready LLM applications with comprehensive tool integration, agent orchestration, and enterprise observability through LangSmith.
