Gemini 4 Argon in Antigravity: Who Gets It, Quota, Rollout

Is Gemini 4 Argon in Antigravity?

Yes, it is rolling out. Google Antigravity's own account on X says Gemini 4 Argon is being rolled out in Antigravity to paid Google AI Pro subscribers, with a separate weekly-only Argon quota for Pro that sits on top of the existing Gemini quota bucket. In practice that means using Argon should not eat into the quota you use for the other Gemini model in Antigravity, but the Argon quota is weekly only, so you do not get a refresh every few hours. Users on X also report that some plans are left out (for example free and trial plans); Google has not listed every exclusion in the posts we read, so check the model picker in your own Antigravity app. Last checked 2026-10-26.

Overview

Google announced Gemini 4 Argon, a model designed for complex, long-running work in software engineering, business research, and cybersecurity. At the announcement the rollout was limited to trusted cyber defenders through the Fairwind program, with paid API customers and Google AI Ultra subscribers named as next in line. Access has since widened, as described above.

Capabilities & Benchmark Claims

Google reports a 1-million-token output limit and strong results on several specialized benchmarks. Those results are Google’s own claims; independent testing and wider access will show how Argon performs in everyday use. For AI-agent developers, the announcement is a promising signal—but the real test is still ahead.
