DSPy's Monty sandbox interpreter updated for 3.5: Rust-based secure Python runtime

dbreunig · x · 2026-11-12

dbreunig's open-source dspy-monty-interpreter has been updated for DSPy 3.5. The project provides a drop-in code interpreter for DSPy's RLM module, built on Monty — a Rust-written sandboxed Python interpreter designed specifically for AI-generated code.

Monty implements a useful subset of the Python standard library (sys, os, pathlib, json, math, asyncio, dataclasses, and more), enabling safe sandboxed execution of model-generated Python code. MIT licensed, 56 stars on GitHub.
