Tools for retrieval of additional information

Written by

Updated at November 6, 2025

Note

We do not recommend using AI Assistant API in new projects. To create AI agents, use the Responses API.

AI assistants can rely on additional information sources, such as internal knowledge bases or web search, to perform tasks. To access these sources, you can use certain specialized tools, i.e., additional modules you can integrate with your AI assistants.

AI Studio provides pre-integrated tools for AI Assistant API:

  • Retrieval
  • WebSearch

You can connect multiple tools to an AI assistant at the same time.
