Arrakis: How To Build An AI Sandbox From Scratch - Abhishek Bhardwaj, OpenAI
Jun 3, 2025 · 40:18
Abhishek Bhardwaj, founder of Arrakis, explains why MicroVM-based AI sandboxes are the next unlock for AI agents, detailing how Arrakis provides secure, fast code execution and computer-use environments. He argues that sandboxes are essential for tool-calling models, reinforcement learning, and multi-tenant security, with Arrakis booting in under 7 seconds and supporting backtracking via snapshot/restore. The talk covers the choice of Cloud Hypervisor over other VMMs, overlayFS storage with per-sandbox read-write layers, iptables-based networking, and a built-in code execution server. A demo shows Claude using Arrakis via MCP to build a collaborative Google Docs clone and then revert to a snapshot, illustrating how a full Linux sandbox enables agents to autonomously debug and iterate without extensive prompting.
