Smol Agents—a lightweight agent framework developed by Hugging Face. It’s designed to run autonomous agents inside your browser, often described as like having a “personal assistant” embedded directly in the web.
Smol Agents: These are compact, self-contained LLM agents that can operate in a local environment (like your browser) with minimal resource usage.
Open Computer Agent: It’s part of Hugging Face’s broader initiative to create open, autonomous systems that interact with your local computer or browser tasks—like browsing, managing files, or interacting with web apps.
Browser-Resident: They don’t need a cloud backend or constant internet access, and they can be customized or extended using tools, APIs, or user instructions.
Use Cases: Automating mundane tasks, summarizing content, filling out forms, writing emails, or interacting with web UIs.

Smol Agents are:
- Minimal AI agents built around language models.
- Designed to autonomously complete tasks by calling tools, interacting with APIs, or controlling software.
- Meant to be simple, transparent, and hackable.
- Suitable for local use, even in environments like a browser or terminal.
Think of a Smol Agent like a small brain that can:
- Receive a goal (like “rename all files with today’s date”),
- Plan steps using reasoning (e.g. “list files” → “rename them”),
- And execute those steps using tools or system commands.
Key Features
Feature | Description |
---|---|
Lightweight | No need for huge infrastructure or servers. |
Composable | You can define your own tools or skills. |
LLM-Powered | Uses small language models (e.g. via Transformers or API). |
Autonomous | Can plan and take multiple steps to reach a goal. |
Runs Anywhere | Browser, terminal, local runtime, etc. |
Example Use Cases
- A browser-based assistant that autofills forms.
- A file management bot on your computer.
- An agent that reads a website and generates summaries.
- Automation for software development (e.g., test code, fix bugs).
Example
pythonCopyEditfrom smolagent import SmolAgent
agent = SmolAgent(goal="Sort all images by date")
agent.add_tool("list_files", list_files_function)
agent.add_tool("sort_images", sort_images_function)
agent.run()
The agent figures out how to use the tools to complete the task.
