Vercel AI SDK 3.3
Vercel AI SDK 3.3 ships unified API for any language model — developers can now swap models without rewriting code.

Why it matters
Vercel's SDK abstraction layer reduces switching costs between AI models, making it easier for developers to adopt new models and compare providers. This shifts power toward model-agnostic tooling and away from single-vendor lock-in.
