Baseten announced a private preview of Carbon, the fourth-generation infrastructure for Blaxel sandboxes, designed to support large-scale agentic workflows. Carbon provides microVM-based sandboxes with dedicated IPv6 addresses, kernel capabilities for runtime enforcement, manual snapshotting, forking, and a direct path from snapshot to production within milliseconds. It also supports NVIDIA's OpenShell runtime for kernel-level policy enforcement.

## Evidence

Verbatim from https://www.baseten.co/blog/announcing-carbon:

> Today we're introducing a private preview of Carbon, Blaxel's fourth infrastructure generation built to support trillions of agents in production. Coming to Baseten soon, Carbon will provide the backbone for sandboxes and broader execution infrastructure for agentic workflows on the Baseten platform.
