Google is preparing Antigravity for Gemini 4 Argon, with new labels appearing around usage limits, subscriptions, and prompts to upgrade to Google AI Ultra. These additions suggest Ultra subscribers could be among the first users to access Argon in the coding app. Google’s September 30 announcement already names Ultra subscribers and paid API customers as the starting point for its broader rollout, after giving access to trusted cyber defenders.

UTM links in Antigravity already point to destinations mentioning "Argon" related params: utm_source=antigravity&utm_campaign=argon_model_selector

Google says Argon is already powering internal workflows and reports a 77.9% score on DeepSWE v1.1, which evaluates longer software engineering tasks. This places Antigravity in Google’s push toward agents that can handle complex coding work over extended periods. The new subscription labels point to rollout preparations, although they do not establish an Antigravity release date.

We also spotted an agent prototype internally called Concierge, with support for real-time voice. It appears to be an early implementation, so its presence does not establish that Google plans to ship it. If released, Concierge could let developers direct agent work through spoken requests.
