How Mux shipped durable video workflows with their @mux/ai SDK

This post details how Mux integrated Vercel's Workflow DevKit into their `@mux/ai` SDK to enable durable AI video workflows. It highlights the problem of AI workflow failures and how Workflow DevKit's "use workflow" and "use step" directives provide opt-in durability without hard infrastructure requirements or new DSLs. The post demonstrates a practical example of a durable video AI workflow and explains how Vercel handles state storage and observability automatically. It also mentions the availability of pre-built workflows for common video AI tasks and the open-source nature of the SDK.
