## Why Included

Vercel’s June gateway data shows cheap volume moving to open-weight models while costly agent workloads stay on frontier models, strengthening the case for risk-based routing.

## Source Summary

In June, open-weight models carried **29% of gateway tokens for under 4% of spend**. Anthropic took **61% of spend on 32% of tokens**, including at least 72% of spend in each high-stakes use case.

## Practical Implication

Builders running coding agents should route by workload: test cheaper models on repeatable, high-volume tasks while reserving costly frontier models for work where errors carry more risk. Track quality and spend separately.
