Set per-user budgets on AI Gateway
Per-user dollar limits and threshold alerts give unattended agents a hard cost boundary across attributed keys and tokens.

Source Summary
AI Gateway can now cap each user's aggregate spend across attributed API keys and app tokens, giving unattended coding agents a hard cost boundary.
Practical Implication
Set a default allowance for every user, then override it for heavy agent users. Production or shared keys should be attributed to the team, and CLI management requires Vercel CLI 59.6.2+.
Agent-Ready Context
AI Gateway now supports **per-user dollar limits** across attributed API keys and app tokens. Requests are rejected at the limit; resets can be daily, weekly, monthly, or disabled, with alerts at **50%, 75%, and 100%**. Set a default allowance for every user, then override it for heavy agent users. Production or shared keys should be attributed to the team, and CLI management requires **Vercel CLI 59.6.2+**. User limits stack with API-key, project, and team budgets, so any applicable cap can block a request. BYOK spend is excluded, and older keys remain team-attributed unless rotated.
