Google AI Studio full-stack app builds now run end-to-end on Gemini 4 Argon and Antigravity
Google AI Studio's full-stack web app creation and deployment is now powered end-to-end by gemini-4-argon and the Antigravity agent harness, going from prompt to Cloud Run.
Creating and seamlessly deploying full-stack web apps in Google AI Studio has taken a massive leap forward—now powered end-to-end by Gemini 4 Argon (gemini-4-argon) and the Antigravity agent harness. You can go from a single prompt, rough sketch, or repo import to a live production web app on Cloud Run in minutes. Here’s what changed under the hood 🧵 (1/6)
1/ Argon + Antigravity Harness in Build Mode AI Studio Build now runs on the core Antigravity Agent harness paired with Gemini 4 Argon (91.9% on Vibe Code Bench, 1M unified context & 1M output). Instead of brittle one-shot codegen, the agent holds full project state, coordinates multi-file edits across the stack, and uses verified execution to test its own changes. (2/6)
