In August 2025, delivered a Stateful Sandbox Executor Demonstration Script in modal-labs/modal-examples. The Python script demonstrates a stateful sandbox executor backed by Jupyter kernels within a Modal sandbox. It executes code inside the sandbox and captures expression results, stdout, and stderr, with examples of simple assignments, printing outputs, and error handling to illustrate the executor’s capabilities. This work strengthens demonstration capabilities for sandboxed execution and lays groundwork for broader adoption and testing of the Modal sandbox environment.
