How Quora uses Modal to run thousands of Python sandboxes simultaneously

What this post added

This post details how Quora integrated Modal Sandboxes into their Poe AI chatbot platform to securely execute LLM-generated code. It highlights Quora's requirements for security, low latency, and reliability, and explains how Modal's existing Sandbox product met these needs without extensive in-house development. The post emphasizes the benefits of Modal's custom container stack (built on gVisor), fast scalability (tested up to 1000 Sandboxes/sec), and networking primitives (Tunnels, IP allowlisting) as key enablers for Quora's use case.
