## TL;DR

Install only the ones you use. - @ai-sdk/react, @ai-sdk/svelte, @ai-sdk/vue, @ai-sdk/solid, @ai-sdk/angular: UI framework bindings. useChat, useCompletion, useObject live here, not in ai. - @ai-sdk/otel: OpenTelemetry integration for telemetry. @ai-sdk/mcp: MCP client support. Newcomers install the wrong package constantly. Install @latest and check its declared ai peer. Keep zod at ^4.1.8 or later.

## When to use

You are seeing this: The map: - ai: the core. streamText, generateText, tool, ToolLoopAgent, convertToModelMessages, createUIMessageStreamResponse, DefaultChatTransport, telemetry. Use this skill when you run into "ai vs @ai-sdk/openai vs @ai-sdk/react: which package does what in v7".

## When not to use

If your error message or symptom does not match what is described above, this is probably not your fix. Search for your exact error text instead of forcing this one to fit.

## Versions

Versions mentioned in the source: 4.1.8. If you are on something much newer or older, the details may have shifted.

Newcomers install the wrong package constantly. The map:

- ai: the core. streamText, generateText, tool, ToolLoopAgent, convertToModelMessages, createUIMessageStreamResponse, DefaultChatTransport, telemetry. The Vercel AI Gateway provider ships inside ai.
- @ai-sdk/openai, @ai-sdk/anthropic, @ai-sdk/google, @ai-sdk/xai, @ai-sdk/azure, @ai-sdk/amazon-bedrock, @ai-sdk/google-vertex, @ai-sdk/mistral, @ai-sdk/groq, @ai-sdk/deepseek, and more: provider packages. One per provider. Install only the ones you use.
- @ai-sdk/react, @ai-sdk/svelte, @ai-sdk/vue, @ai-sdk/solid, @ai-sdk/angular: UI framework bindings. useChat, useCompletion, useObject live here, not in ai.
- @ai-sdk/otel: OpenTelemetry integration for telemetry. @ai-sdk/mcp: MCP client support.

Version facts that bite:
1. Framework packages have independent majors. In the ai 7 era, @ai-sdk/react is 4.x, @ai-sdk/svelte is 5.x, @ai-sdk/vue is 4.x. There is no @ai-sdk/react@7. Install @latest and check its declared ai peer.
2. The old community packages (ai/openai style imports) are long gone. Since v4 everything is @ai-sdk/* scoped. Tutorials importing from 'ai/openai' are stale.
3. Provider packages depend on @ai-sdk/provider and @ai-sdk/provider-utils. Mismatched provider majors against ai cause UnsupportedModelVersionError and LanguageModelV1 type errors. Upgrade them together.
4. The application package is named ai, not @ai-sdk/ai. Import errors from 'ai'; provider-level errors can also come from '@ai-sdk/provider' directly.
5. Keep zod at ^4.1.8 or later. The SDK's tool and object schemas assume it, and older zod tanks TypeScript performance.
