​
Initialization

To integrate with Runloop and your preferred LLM provider, initialize the respective SDK clients.

from anthropic import Anthropic
from runloop_api_client import Runloop
import os

# Initialize clients
anthropic = Anthropic(api_key=os.environ.get("ANTHROPIC_API_KEY"))
runloop = Runloop(bearer_token=os.environ.get("RUNLOOP_API_KEY"))

​
Defining Prompts

Defining a clear, actionable prompt ensures accurate LLM responses.

system_prompt = "You are a helpful coding assistant that can generate and execute python code. "
"You only respond with the code to be executed and nothing else."
"Strip backticks in code blocks."

prompt = 
"Write a Python script that generates a maze. The script should:"
"1. Accept a size parameter from command line arguments"
"2. Generate a random maze of the specified size. Remember to make the maze solvable "
"and easy and to make it clear the outer borders of the maze."
"3. Print the maze where '#' represents walls and ' ' represents paths."
"Mark the Maze start with 'S' and end with 'E'"
"4. Use argparse for command line argument parsing"
"The code should be in the format of a Python script that can be run directly"
"with 'python gen_maze.py --size 5'."
"ONLY output the code and do NOT wrap the code in markdown! The code should begin "
"with an import and end with a print statement."

​
Generating Code

Send the defined prompts to the LLM’s message endpoint, configure parameters and extract the generated code from the response.

# Generate code using Claude
response = anthropic.messages.create(
    model="claude-3-5-sonnet-20240620",
    max_tokens=1024,
    messages=[
        {"role": "assistant", "content": system_prompt},
        {"role": "user", "content": prompt}
    ]
)
maze_generation_script = response.content[0].text

​
Running Code on a Devbox

After retrieving the code from the LLM, execute it in a Runloop Devbox.

devbox = runloop.devboxes.create_and_await_running()
print("Devbox ID:", devbox.id)

runloop.devboxes.write_file_contents(
  devbox.id,
  file_path="gen_maze.py",
  contents=code
)

result = runloop.devboxes.execute_sync(
  devbox.id,
  command=f"python gen_maze.py --size {size}"
)

if not result.exit_status:
  print("Maze generated successfully\n", result.stdout)
  return result.stdout
else:
  print("Script execution failed:", result.stderr)
  return result.stderr

The examples below show Integration of Runloop with popular frameworks and LLM providers.

The examples follow this structure:

  1. Client Initialization: Set up SDK clients with environment variables.
  2. Prompt Definition: Use pre-defined system and user prompts.
  3. Code Generation: Generate code based on the prompts.
  4. Execution: Run the code in a secure Runloop Devbox.
Prompts are defined above and reused across examples.
Handle the non-null ”!” operator in examples with default values or as needed.
