[koxudaxi]

Environment details

• Programming language: Python
• OS: macOS 15.1.1
• Language runtime version: Python 3.9
• Package version: google-generativeai (latest) 0.6.0

Steps to reproduce

1. I create Python file with below code:

from pydantic import BaseModel


class MyConfig(BaseModel):
    """My custom config for the Google call."""
    config: GenerationConfigDict

Problem Description

I find problem when I try to use TypedDict class from google.genai.types with Pydantic model in Python version less than 3.12. Pydantic show error because it need typing_extensions.TypedDict not typing.TypedDict for Python version under 3.12.

I think solution is change TypedDict import in google.genai.types from typing.TypedDict to typing_extensions.TypedDict. But types.py is auto-generated file, so I cannot change directly.

I try to fix code generator but I cannot find build manual or code generator source code.

This problem happen to everyone who use TypedDict class from google.genai.types with Pydantic in Python version under 3.12. Please fix code generator.

Thanks!
