Key changes: - Use vertex.WithGoogleAuth() for proper VertexAI authentication - Add comprehensive test suite for VertexAI Claude models - Fix nil pointer panic by ensuring config initialization in tests - Update error handling to expect real Google Cloud API responses - Add model routing logic to correctly handle Claude vs Gemini models All 16 VertexAI tests now pass, confirming proper integration with Google Cloud authentication and correct endpoint format for VertexAI Anthropic models. 🤖 Generated with [Claude Code](https://claude.ai/code) Co-Authored-By: Claude --- go.mod | 8 +
