The model had previously been available in Antigravity to Google AI Ultra subscribers.
According to 9to5Google, Argon use in Antigravity has a separate weekly quota in addition to the existing Gemini 3.8 Flash quota. Google describes Argon as intended for harder problems. The report says the rollout is active and was observed by the publication.
The article also relays Google internal-use examples, including closing 97 of 134 stale or duplicate bug reports in under three hours and finding four critical security bugs in an access-control review.
