Daytona sandbox example

This example shows how to use DaytonaRunner from plain Python code, such as a reward function, evaluation script, or data-prep utility.

Install

uv sync --extra sandbox
export DAYTONA_API_KEY=your-key

Run

uv run python examples/sandbox_daytona/reward_example.py

Notes

• DaytonaRunner is the synchronous entry point for non-async user code.
• Each runner instance creates one sandbox and keeps it warm across multiple run() calls.
