Best practice for streaming AI responses in Next.js App Router?

Hi guys,

I’m currently building an AI-driven feature for my agency's latest project. I’m using the ai SDK from Vercel, but I’m curious how you guys are handling [Specific issue, e.g., edge function timeouts or persistent chat history].

Are you sticking with standard API routes, or are you moving everything into Server Actions for this?

Looking for advice on the most scalable way to handle long-running AI agents without blocking the UI. Thanks!
