Smolagents is a lightweight library that allows users to run powerful intelligent agents with just a few lines of code. It is characterized by simplicity and supports any language model (LLM), including models on Hugging Face Hub and those integrated via LiteLLM from OpenAI and Anthropic. It specifically supports code agents, where the agents perform actions by writing code instead of writing code themselves. Smolagents also offers safe code execution options, including a secure Python interpreter and a sandbox environment using E2B.
