VertexAI Claude Adaptive Thinking
=================================
Cookbook example demonstrating adaptive thinking with output_config on VertexAI.
For Claude 4.6 VertexAI models, use adaptive thinking with the effort parameter
to control thinking depth. Valid effort values:
- "low": Most efficient, significant token savings
- "medium": Balanced approach with moderate savings
- "high": Default, high capability for complex reasoning
- "max": Absolute maximum capability (Opus 4.6 only)
Prerequisites:
- Set GOOGLE_CLOUD_PROJECT and CLOUD_ML_REGION environment variables
- Authenticate with: gcloud auth application-default login
