smolagents

smolagents is Hugging Face's lightweight agentic framework that enables building robust AI agents in just a few lines of code. Unlike traditional tool-calling approaches, smolagents uses 'code agents' that write and execute Python code snippets to perform actions, achieving 30% reduction in steps and LLM calls with superior performance on complex benchmarks. With only ~1,000 lines of core logic, it provides first-class support for code-based reasoning while maintaining security through sandboxed execution via E2B, Modal, Docker, or Pyodide+Deno WebAssembly. Deep Hugging Face Hub integration enables easy tool sharing, and the framework supports any LLM provider including transformers, Ollama, OpenAI, Anthropic, and more via LiteLLM integration.
