What the AI SDK Is

The AI SDK by Vercel (the ai package on npm) is a TypeScript toolkit for building AI applications. It provides a unified API across model providers for text generation, structured output, tool calling, agents, embeddings, and framework UI integrations.

Critical: Do Not Trust Your Own Memory

Whatever you remember about the AI SDK is likely outdated. The SDK changes frequently across versions - APIs are renamed, removed, and added. Your training data almost certainly contains obsolete APIs, deprecated patterns, and model IDs that no longer exist. UI hooks like useChat are among the most frequently changed APIs, so be especially careful with client code.

Never write AI SDK code from memory. Always verify every API, option, and pattern against the documentation and source code for the version that is actually installed in the project.

Use the Bundled, Version-Matched Docs

The ai package ships its full documentation and source code inside node_modules. These always match the installed version, so trust them over anything you remember.
