Configurations to generate content with Multimodal AI Model

This sample demonstrates how to provide user configurations to a Multimodal AI Model

Code sample

Python

Before trying this sample, follow the Python setup instructions in the Vertex AI quickstart using client libraries. For more information, see the Vertex AI Python API reference documentation.

To authenticate to Vertex AI, set up Application Default Credentials. For more information, see Set up authentication for a local development environment.
