# Vercel CEO on splitting models from agents: the infrastructure layer argument

> Vercel CEO Guillermo Rauch makes an argument in this piece that is really about avoiding lock-in. As AI agents move into production, he says, companies should treat the stack the way they treat traditional software, as modular components, model, harness, data platform, sandbox and gateway, each sourced independently and swappable when something better or cheaper comes along. The strategic tension he is pointing at is sharp. The big model labs are steadily expanding upward into the infrastructure and agent tooling around their models, which puts them in direct competition with platforms like Vercel that want to be the neutral layer underneath. If you build your agent tightly around one lab's full stack, you inherit that lab's pricing power and roadmap; if you keep the model as a pluggable part, you keep leverage. Whether you buy Vercel's framing or read it as a pitch for Vercel's own position, the underlying question is a good one for anyone building with AI right now. The pace of model releases this month alone shows how quickly the best option changes, and an architecture that lets you switch without a rewrite is starting to look less like caution and more like common sense.
