Gemini exposes both consumer-oriented Google AI Studio keys and enterprise paths through Vertex AI. Choose based on contract, data residency, and whether you need VPC-SC or audit logs your InfoSec team already consumes.

  • Never expose API keys in mobile or browser bundles—proxy through your API with auth.
  • Stream tokens for long answers; cap output length and cost per request.
  • Log latency, prompt hash, and safety block reasons without storing raw PII prompts in hot logs.

This foundation sets you up for tool use and multi-turn agents on top of Gemini.
