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

What this post added

Mux has integrated their @mux/ai SDK with Vercel's Workflow DevKit to enable durable AI video workflows. This integration allows developers to build complex, multi-step AI processes without managing complex infrastructure. The SDK leverages "use workflow" and "use step" directives for opt-in durability, providing automatic retries, state persistence, and observability when deployed in a Workflow DevKit environment, while remaining a standard Node.js package otherwise. This enables features like content moderation, chapter generation, and summarization for video processing.
