pip install langchain-modal
创建沙箱后端
In Python, you create the sandbox using the provider SDK, then wrap it with the deepagents backend.
import modal
from langchain_modal import ModalSandbox
app = modal.App.lookup("your-app")
modal_sandbox = modal.Sandbox.create(app=app)
backend = ModalSandbox(sandbox=modal_sandbox)
result = backend.execute("echo hello")
print(result.output)
Use with Deep Agents
import modal
from langchain_anthropic import ChatAnthropic
from deepagents import create_deep_agent
from langchain_modal import ModalSandbox
app = modal.App.lookup("your-app")
modal_sandbox = modal.Sandbox.create(app=app)
backend = ModalSandbox(sandbox=modal_sandbox)
agent = create_deep_agent(
model=ChatAnthropic(model="claude-sonnet-4-20250514"),
system_prompt="You are a coding assistant with sandbox access.",
backend=backend,
)
result = agent.invoke(
{"messages": [{"role": "user", "content": "Install numpy and calculate pi"}]}
)
Cleanup
You are responsible for managing the sandbox lifecycle via Modal.
When you are done, terminate the sandbox.
