Vercel AI SDK
Software
Agent framework layer inside an AI app-builder, handling the code-generation agent within the application
"When I asked Codex to build Replit, it used Convex for the database and then it used the AI SDK from Vercel to have an AI — the agent that generates the code inside the app. It just used these pre-built building blocks like Legos."
More source quotes
Agent loop abstraction for Gusto Co-founder; model switching; tool use
"We use Cloudflare Workers for the actual agent loop and Vercel AI SDK. That's it. Our stack is surprisingly simple. If you use AI SDK you get to switch your model. That's it. It can look up files. It can have tools. It's really not that scary and complicated."
"And I will say Vercel's AI gateway is a great way to kind of code once and just flip a model on the go. So, highly recommend checking out Vercel AI gateway as a way to quickly swap models, rather than having to recode it."
