Pydantic open-sources Monty: a Rust-based Python sandbox for running AI-generated code (8.4k stars)

- samuelcolvin (Pydantic) announced Monty, a secure Python sandbox written in Rust for executing LLM-generated code, avoiding the latency, complexity and cost of container-based sandboxes.
- Two forms: OSS Monty (MIT-licensed Python 3.14 sandbox, installable as a package) and Full Monty (commercial server exposing the same sandbox over WebSockets). The repo already has 8.4k stars.
- Context from the quoted post: serving 100M users of an agent product like Meta's Muse would need 25M live VMs — about 65K CPUs and 75PB of DRAM, roughly $2.8B at public pricing — underscoring why more efficient agentic compute is needed.
