 **Strengths:**
 - Largest context window (2M tokens)
 - Native multimodal (text, image, video, audio)
-- Strong at structured data
-- Good coding abilities
+- Vertex AI support enables enterprise VPC/IAM integration
 
 **Considerations:**
-- Some features region-limited
-- API changes more frequently
+- Different endpoints for public vs enterprise deployments
