Assessment
The Vercel AI SDK is an application library for streaming interfaces, tools, and model calls. v0, Vercel Sandbox, and merge-queue products cover different jobs; the SDK provides no worker VM or CI gate.
Strengths
- Apache-2.0, multi-provider TypeScript toolkit.
- Streaming UIs and tools done well.
- Separate domain from v0 and Sandbox.
Limitations
- No worker VM or CI gate.
- App-shaped, not repo-shaped.
- Vercel gravity without being required.
