pydantic/monty: Minimal Secure Python Interpreter in Rust for AI — Microsecond Startup vs 200ms Docker

GitHub·medium signal

Pydantic's Monty is a Rust-based Python interpreter purpose-built for executing LLM-generated code safely without containerization overhead. Starts in microseconds (vs ~200ms for Docker), with filesystem/network/env blocked by default and enabled only through explicit external function calls. Features execution state snapshotting (serialize to bytes and resume later) and resource limits on memory, allocations, stack depth, and execution time. 6.6K stars, still experimental.
