AI SDK Documentation

When you need up-to-date information about the AI SDK:

If using ai@6.0.34 or above

Search the bundled documentation and source code in node_modules/ai/ :

• Documentation: grep "your query" node_modules/ai/docs/

• Source code: grep "your query" node_modules/ai/src/

To find specific files:

• glob "node_modules/ai/docs/**/*.mdx" for documentation files

• glob "node_modules/ai/src/**/*.ts" for source files

Provider packages (@ai-sdk/openai , @ai-sdk/anthropic , etc.) also include bundled docs in their respective node_modules/@ai-sdk/<provider>/docs/ directories.

When in doubt, update to the latest version of the AI SDK.

Otherwise

• Search the docs: https://ai-sdk.dev/api/search-docs?q=your_query

• The response includes matches with links ending in .md

• Fetch those .md URLs directly to get plain text content (e.g. https://ai-sdk.dev/docs/agents/building-agents.md )

Use these resources for current API details, examples, and usage patterns.

Provider-Specific Information (ai@6.0.34+)

For questions about specific providers (OpenAI, Anthropic, Google, etc.), search their dedicated packages:

• Provider documentation: grep "your query" node_modules/@ai-sdk/<provider>/docs/

• Provider source code: grep "your query" node_modules/@ai-sdk/<provider>/src/

To find provider files:

• glob "node_modules/@ai-sdk/<provider>/docs/**/*.mdx" for provider documentation

• glob "node_modules/@ai-sdk/<provider>/src/**/*.ts" for provider source files

This is especially important for providerOptions , which are provider-specific settings passed to model calls. Each provider has unique options documented in their package.
