This document provides examples that demonstrate how to use agents.
The Assistant API is being deprecated. Migrate to the Responses API as an alternative. The Responses API includes multiple built-in tools and supports multi-turn context management.
To run the following examples, you need Python SDK 1.18.0 or later and Java SDK 2.14.2 or later. To update the Python SDK, run the pip install -U dashscope command.

Call tools using the Assistant
You may need to request permission to use the tools.
