Why this app routes Claude through Vercel's AI Gateway

What changed: Vercel AI Gateway went GA, offering a single endpoint for 100+ AI models with observability, failover, and zero data retention.

Why it matters for us: our tutor uses 'anthropic/claude-sonnet-4-6' as a plain string — no provider-specific SDK installed. If Anthropic has an outage, the Gateway can fall over to another provider without redeploying.

What to try:

Open Lesson 14 (Data & Privacy) and ask the tutor: "Where does my conversation actually go when I use the tutor?" The answer should reference both the lesson's privacy content and the Gateway architecture above.
