Sandbox Forking SDK & Org Metrics
This release improves SDK capabilities with new experimental methods for sandbox forking and snapshot creation. All SDKs — Go, Java, Python, Ruby, and TypeScript — now support copy-on-write forking and programmatic snapshot creation with configurable timeouts, enabling users to clone sandbox environments and capture their full state.
For platform operators, a new organization-level metrics exporter pushes per-region CPU, memory, and storage usage to OTEL collectors every 60 seconds. This enables real-time quota monitoring through preconfigured dashboards. The collector also gains organization-based routing as a fallback.
The docs expand with a new veRL guide for reinforcement learning workflows and documentation covering sandbox forking and snapshot creation.
