## Summary

Guillermo Rauch says Vercel's AI Gateway virtual models work like DNS for models, with an alias that resolves to a model and enables traffic steering. He says this lets teams avoid staying on old model versions and reduces cost and decision paralysis. The feature uses a single virtual model ID across agents to centrally manage model strings and configs, update to new models immediately, and enforce Zero Data Retention.

Solves a huge number of problems. From not having teams stuck on old model versions, to saving on costs, to removing “decision paralysis”. Try it!
