## When it is useful

Build realtime bidirectional streaming apps with the Gemini Live API (WebSocket audio/video/text, VAD, ephemeral tokens).

## The Catch

Loud: Gemini API Free Tier is real $0 (no CC) for eligible Flash models with hard RPM/RPD caps that change — do not invent numbers. Free-tier prompts may improve Google products. Pro/paid for higher quotas and production scale; Live/Omni video burn Free caps fast. Product proprietary Google SaaS — skills Apache-2.0, API is not OSS. Distinct from Firebase BO (ai-logic HOLD).
