# Sandbox Upgrade Notice

> Nov 5, 2026: Miles can run its Harbor and OpenEnv agent task environments on Novita Sandbox as the sandbox backend for reinforcement learning rollouts.

## What's New

### Miles Integration

* Run [Miles](https://docs.novita.ai/guides/sandbox-integrations-miles.md) agent task environments on Novita Sandbox. Miles is an open-source framework for large-scale reinforcement learning and model post-training. Its Harbor and OpenEnv recipes now accept Novita as the sandbox backend, so each rollout episode runs in its own isolated sandbox while the training stack stays on your GPUs.
