Gemini 3 API Best Practices for Production Apps

A quick checklist for using Gemini 3 in production, covering safety, latency, and observability.

Think in flows, not single prompts

Production Gemini 3 apps usually rely on multi-step flows: classification → planning → tool calls → final drafting. Designing the flow explicitly makes it easier to debug, evaluate, and iterate.

Key things to monitor

  • Latency per step and per user-visible action.
  • Failure modes for tool calls or external APIs.
  • Safety outcomes: blocked prompts, red-team logs, and user reports.

Treat prompts and system instructions as first-class configuration. Version them, review them, and roll out changes gradually like any other production dependency.
