LLM Sandbox

Securely Execute LLM-Generated Code with Ease

LLM Sandbox is a lightweight and portable sandbox environment designed to run large language model (LLM) generated code in a safe and isolated manner using Docker containers. This project aims to provide an easy-to-use interface for setting up, managing, and executing code in a controlled Docker environment, simplifying the process of running code generated by LLMs.

Features

  • Easy Setup: Quickly create sandbox environments with minimal configuration.
  • Isolation: Run your code in isolated Docker containers to prevent interference with your host system.
  • Flexibility: Support for multiple programming languages.
  • Portability: Use predefined Docker images or custom Dockerfiles.
  • Scalability: Support Kubernetes and remote Docker host.

Installation

Using Poetry

  1. Ensure you have Poetry installed.
  2. Add the package to your project:
poetry add llm-sandbox

Using pip

  1. Ensure you have pip installed.
  2. Install the package:
pip install llm-sandbox

Usage

Session Lifecycle

The SandboxSession class manages the lifecycle of the sandbox environment, including the creation and destruction of Docker containers. Here’s a typical lifecycle:

  1. Initialization: Create a SandboxSession object with the desired configuration.
  2. Open Session: Call the open() method to build/pull the Docker image and start the Docker container.
  3. Run Code: Use the run() method to execute code inside the sandbox. Currently, it supports Python, Java, JavaScript, C++, Go, and Ruby. See examples for more details.
  4. Close Session: Call the close() method to stop and remove the Docker container. If the keep_template flag is set to True, the Docker image will not be removed, and the last container state will be committed to the image.

Example

Here's a simple example to demonstrate how to use LLM Sandbox:

from llm_sandbox import SandboxSession

# Create a new sandbox session
with SandboxSession(image="python:3.9.19-bullseye", keep_template=True, lang="python") as session:
    result = session.run("print('Hello, World!')")
    print(result)

# With custom Dockerfile
with SandboxSession(dockerfile="Dockerfile", keep_template=True, lang="python") as session:
    result = session.run("print('Hello, World!')")
    print(result)

# Or default image
with SandboxSession(lang="python", keep_template=True) as session:
    result = session.run("print('Hello, World!')")
    print(result)

LLM Sandbox also supports copying files between the host and the sandbox:

from llm_sandbox import SandboxSession

with SandboxSession(lang="python", keep_template=True) as session:
    # Copy a file from the host to the sandbox
    session.copy_to_runtime("test.py", "/sandbox/test.py")

    # Run the copied Python code in the sandbox
    result = session.run("python /sandbox/test.py")
    print(result)

    # Copy a file from the sandbox to the host
    session.copy_from_runtime("/sandbox/output.txt", "output.txt")

For other languages usage, please refer to the examples.

You can also use remote Docker host as below:

import docker
from llm_sandbox import SandboxSession

tls_config = docker.tls.TLSConfig(
    client_cert=("path/to/cert.pem", "path/to/key.pem"),
    ca_cert="path/to/ca.pem",
    verify=True
)
docker_client = docker.DockerClient(base_url="tcp://<your_host>:<port>", tls=tls_config)

with SandboxSession(
    client=docker_client,
    image="python:3.9.19-bullseye",
    keep_template=True,
    lang="python",
) as session:
    result = session.run("print('Hello, World!')")
    print(result)

For Kubernetes usage, please refer to the examples. Essentially, you just need to set the use_kubernetes flag to True and provide the Kubernetes client, or leave it as the default for the local context.

Integration

With Langchain integration, you can easily run the generated code in a safe and isolated environment. Here's an example of how to use LLM Sandbox with Langchain:

from typing import Optional, List
from llm_sandbox import SandboxSession
from langchain import hub
from langchain_openai import ChatOpenAI
from langchain.tools import tool
from langchain.agents import AgentExecutor, create_tool_calling_agent


@tool
def run_code(lang: str, code: str, libraries: Optional[List] = None) -> str:
    """
    Run code in a sandboxed environment.
    :param lang: The language of the code.
    :param code: The code to run.
    :param libraries: The libraries to use, it is optional.
    :return: The output of the code.
    """
    with SandboxSession(lang=lang, verbose=False) as session:  # type: ignore[attr-defined]
        return session.run(code, libraries).text


if __name__ == "__main__":
    llm = ChatOpenAI(model="gpt-4o", temperature=0)
    prompt = hub.pull("hwchase17/openai-functions-agent")
    tools = [run_code]

    agent = create_tool_calling_agent(llm, tools, prompt)
    agent_executor = AgentExecutor(agent=agent, tools=tools, verbose=True)
    output = agent_executor.invoke(
        {
            "input": "Write python code to calculate Pi number by Monte Carlo method then run it."
        }
    )
    print(output)

    output = agent_executor.invoke(
        {
            "input": "Write python code to calculate the factorial of a number then run it."
        }
    )
    print(output)

    output = agent_executor.invoke(
        {"input": "Write python code to calculate the Fibonacci sequence then run it."}
    )
    print(output)

For Llama-Index:

from typing import Optional, List
from llm_sandbox import SandboxSession

from llama_index.llms.openai import OpenAI
from llama_index.core.tools import FunctionTool
from llama_index.core.agent import FunctionCallingAgentWorker


import nest_asyncio

nest_asyncio.apply()


def run_code(lang: str, code: str, libraries: Optional[List] = None) -> str:
    """
    Run code in a sandboxed environment.
    :param lang: The language of the code, must be one of ['python', 'java', 'javascript', 'cpp', 'go', 'ruby'].
    :param code: The code to run.
    :param libraries: The libraries to use, it is optional.
    :return: The output of the code.
    """
    with SandboxSession(lang=lang, verbose=False) as session:  # type: ignore[attr-defined]
        return session.run(code, libraries).text


if __name__ == "__main__":
    llm = OpenAI(model="gpt-4o", temperature=0)
    code_execution_tool = FunctionTool.from_defaults(fn=run_code)

    agent_worker = FunctionCallingAgentWorker.from_tools(
        [code_execution_tool],
        llm=llm,
        verbose=True,
        allow_parallel_tool_calls=False,
    )
    agent = agent_worker.as_agent()

    response = agent.chat(
        "Write python code to calculate Pi number by Monte Carlo method then run it."
    )
    print(response)

    response = agent.chat(
        "Write python code to calculate the factorial of a number then run it."
    )
    print(response)

    response = agent.chat(
        "Write python code to calculate the Fibonacci sequence then run it."
    )
    print(response)

    response = agent.chat("Calculate the sum of the first 10000 numbers.")
    print(response)
