The [AI Gateway](https://vercel.com/blog/ai-gateway), currently in alpha for all users, lets you switch between ~100 AI models without needing to manage API keys, rate limits, or provider accounts.

[Vercel Observability ](https://vercel.com/d?to=%2F%5Bteam%5D%2F%5Bproject%5D%2Fobservability%2Fai&title=AI+Observability)now includes a dedicated AI section to surface metrics related to the AI Gateway. This update introduces visibility into:

- Requests by model
- Time to first token (TTFT)
- Request duration
- Input/output token count
- Cost per request (free while in alpha)

You can view these metrics across all projects or drill into per-project and per-model usage to understand which models are performing well, how they compare on latency, and what each request would cost in production.
