Details
Auto routes your request through the Vercel AI Gateway to Claude Sonnet 5. If that provider is degraded the gateway serves the same model from a backup host, so your conversation keeps moving without changing which model answers you. If your token budget is running low it switches to a lighter Claude model so you can keep chatting.
