# Vercel CEO Guillermo Rauch: Splitting Models from Agents Is Key to Production Optimization

## AI commentary

> Guillermo Rauch's view strikes at the heart of AI engineering—while everyone races for more powerful models, he reminds us that cost and maintainability are the real barriers in production. This is especially valuable for teams transitioning from prototype to scale.

## At a glance

In an interview with TechCrunch, Vercel CEO Guillermo Rauch argues that when optimizing AI applications for production, the underlying models must be separated from the agent logic. He highlights that model price/performance is the decisive factor, and that agents should exist as an independent orchestration layer to improve flexibility, observability, and cost control. This view reflects the heated debate in AI engineering around modular architecture.

## Key points

- Separating models from agents improves observability and cost efficiency in production.
- Price/performance ratio, not just capability, is the core metric for selecting models.
- Agents should evolve as an independent orchestration layer, not be tightly coupled with models.
- This view challenges the common practice of tightly coupling models with agents in many AI products.

"The reality is, when you're optimizing for production, you start looking at a price/performance," Guillermo Rauch tells TechCrunch.
