Have you ever wondered how to run AI-generated code in production safely? As AI agents become more sophisticated at generating code, the challenge isn't just about creating code—it's about executing it safely. To solve this critical challenge, this guide combines LangChain's powerful AI capabilities with Daytona's secure sandbox environments.

Picture LangChain as your AI code chef, cooking up sophisticated solutions, while Daytona acts as your secure test kitchen where these creations can be safely tried and tested. Together, they provide a robust framework for generating and executing AI code without compromising security.

TL;DR
  • Generate code confidently using LangChain's AI capabilities

  • Execute it securely in Daytona's isolated environments

  • Manage resources effectively at scale

  • Maintain complete control over the execution environment

Whether you're building AI-powered developer tools or implementing automated code generation in your pipeline, this integration provides the security and flexibility you need.

What is Daytona?

Daytona is an open-source development environment manager designed to create instant, fully-configured development environments across both local and cloud infrastructures. Its architecture supports deployment on all major cloud providers and platforms, while offering a self-hosted option ideal for enterprise and security-sensitive applications.

What sets Daytona apart is its comprehensive API for automated sandbox management through "Workspaces" - isolated development environments that provide secure boundaries for code execution. The platform offers native SDK support for both Python and TypeScript, making it seamless to integrate Daytona's capabilities into existing projects. With its robust infrastructure, Daytona enables automated environment provisioning, resource management, and secure code execution at scale.

Why Sandbox AI-Generated Code?

When working with AI-generated code, security is paramount. AI models might generate code that could:

  • Access system resources inappropriately

  • Make unauthorized network calls

  • Consume excessive memory or CPU resources

  • Perform changes to the system configuration

Daytona's workspace isolation provides a secure boundary for executing such code, making it an ideal solution for AI agent implementations.

What is LangChain?

LangChain is a framework designed to simplify the creation of applications using large language models (LLMs). It provides a modular architecture for combining LLMs with other tools and data sources, making it easier to build complex AI applications. The framework excels at tasks like prompt management, LLM output handling, and creating sophisticated chains of operations. For our use case, LangChain's ability to manage structured interactions with language models makes it an ideal choice for generating and processing code.

Building an AI Code Generator with LangChain and Daytona

Let's walk through creating a practical example that combines LangChain's code generation capabilities with Daytona's secure execution environment.

Setting Up the Environment

First, install the required packages:

1pip install langchain langchain-community openai daytona_sdk

The Code Generation Component

Here's our implementation of a code generator using LangChain:

1from langchain_community.llms import OpenAI
2from langchain.chains import LLMChain
3from langchain.prompts import PromptTemplate
4from langchain.chains import SimpleSequentialChain
5import os
6
7# Set your OpenAI API key
8os.environ["OPENAI_API_KEY"] = "your-api-key-here"
9
10# Create a prompt template for code generation
11code_generation_prompt = PromptTemplate(
12 input_variables=["language", "task"],
13 template="""
14You are an expert {language} developer. Write clean, efficient, and well-documented code for the following task:

213. Example usage if applicable

25)
26
27# Initialize the LLM with lower temperature for more focused code generation
28llm = OpenAI(
29 temperature=0.2,
30 max_tokens=1000
31)
32
33# Create the code generation chain
34code_chain = LLMChain(
35 llm=llm,
36 prompt=code_generation_prompt,
37 verbose=True
38)
39
40def generate_code(language: str, task: str):
41 """
42 Generate code for a given task in the specified programming language.
43 """
44 return code_chain.run({
45 "language": language,
46 "task": task
47 })

Adding Daytona Integration

To safely execute the generated code, we'll now integrate Daytona into our workflow. The first step is to locate your Daytona API key and server URL. You can easily retrieve this information by running the command 'daytona config -k' in your terminal. This command will display both the URL and API key you need.

1from daytona_sdk import Daytona, DaytonaConfig, CreateWorkspaceParams
2
3def execute_in_sandbox(code: str):
4 """
5 Execute generated code in a Daytona workspace sandbox.
6 """
7 # Initialize Daytona with your configuration
8 config = DaytonaConfig(
9 api_key="DAYTONA_API_KEY",
10 server_url="DAYTONA_SERVER_URL",
11 target="local"
12 )
13 daytona = Daytona(config=config)
14
15 # Create a Python workspace
16 params = CreateWorkspaceParams(language="python")
17 workspace = daytona.create()
18
19 try:
20 # Execute the code in the sandbox
21 response = workspace.process.code_run(code)
22
23 if response.code != 0:
24 return f"Error: {response.code} {response.result}"
25 return response.result
26 finally:
27 # Always clean up the workspace
28 daytona.remove(workspace)
29
30# Example usage
31if __name__ == "__main__":
32 # Generate Python code
33 task = "Create a function that takes a list of numbers and returns the moving average with a specified window size"
34 generated_code = generate_code("Python", task)
35
36 # Execute in sandbox
37 result = execute_in_sandbox(generated_code)
38 print("Code execution result:", result)

Benefits of This Approach

  1. Security: All code execution happens in isolated Daytona workspaces, preventing any potential system access or resource abuse.

  2. Resource Management: Daytona workspaces can be configured with specific resource limits, ensuring controlled execution.

  3. Clean Environment: Each execution starts in a fresh workspace, eliminating any potential side effects from previous runs.

  4. Automated Cleanup: The workspace is automatically removed after execution, maintaining system cleanliness.
