📄 Description

Related Issues or Context

Thanks to @jortegac for migrating vertex_ai to the Google Gen AI SDK! However, some features were not included. This PR aims to add these missing capabilities:

  • Support for thinking output.
  • Support for thinking budget configuration.
  • Optimize the Grounding Search feature (by removing the unsupported dynamic_threshold).
