What's Good
One SDK, every model provider. Streaming responses, tool calling, structured outputs—the AI SDK handles the details while you write against a unified interface. Swap between OpenAI, Anthropic, Google, and more without changing application code.
The Catch
Vercel-optimized, which is great on Vercel and requires more work elsewhere. Abstraction means some provider-specific features are harder to access.
Verdict
The SDK for AI applications in the Next.js ecosystem.
