smolagents

elegant agents that write and run code

free — Apache-2.0 (open source)#lightweight#research-agents-where-th

a tiny, elegant take where the agent writes and executes python instead of emitting json tool calls — ideal for research and simple production tasks, minimal on the machinery serious agents need.

smolagents from hugging face centres on code-agents: the react loop where the model writes and runs python each step, rather than emitting json tool calls. it's deliberately barebones and genuinely elegant, with sandboxed execution via e2b, modal, docker or blaxel, and managed sub-agents for multi-agent. it's cross-provider across hugging face, inference and litellm models.

by design it's thin on production reliability primitives — no durable execution, limited human-in-the-loop — so it shines for lightweight and research work more than for hardened production agents. within that scope, the code-first paradigm is powerful.

the description above is ours, condensed from the ranking. pricing moves — check it on the vendor's own page before you rely on it.

we researched this category against vendors' own pricing pages and licence files. that is where this line comes from — not from the vendor, and not from anything they paid for.
