Google's full AI stack, mapped: Gemini 4 Argon, Antigravity and six more layers
A post lays out Google's full AI stack, listing Gemini 4 Argon as the frontier reasoning layer alongside Antigravity, Nano Banana, Omni and Spark.
Google Gemini is filling out a full stack: frontier models, an agent platform that can route across them, native creation, and voice then the same stack surfaces in consumer apps, Workspace, and developer APIs. 1. Frontier reasoning — Gemini 4 Argon 2. Antigravity - multi-agent orchestration across models 3. Image + video - Nano Banana and Gemini Omni 4. 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
