Live voice - speech-to-speech, plus STT, TTS, and translate 5. Cyber - Argon for long-horizon defense, via the Fairwind program 6. Spark - personal agent across apps and Workspace 7. Surfaces - Search, Android, Gmail, Docs, Meet, Photos, Shorts Platform - API, AI Studio, ADK, Managed Agents 8. Ondevice — Gemma via the Antigravity SDK
