Key points
- Google opened Gemini 4 Argon to paying Gemini app and AI Mode users on Pro and Ultra plans, with Antigravity limited to Ultra.
- API pricing is a temporary introduction rate that Ars Technica says doubles after November 30, which affects any workflow budgeted on today's rates.
- Google reports internal results: agentic code submissions up more than 35% and rollbacks down nearly a third among teams using Argon in Antigravity.
- Free users are left out for now, and Google has not said when or whether lower tiers will get Argon in Antigravity.
Why it matters for marketers: Marketers building agent workflows on Gemini get a cheaper frontier model for a limited window, but must budget for a price jump and plan tier limits.
Google has launched Gemini 4 Argon, its newest frontier model, after a limited early release to trusted cyber defenders. Developers and enterprises can reach it through the API, while consumers need a paid plan. Pro and Ultra subscribers get it in the Gemini app and AI Mode in Search, and Antigravity access is restricted to Ultra.
Google says Argon leads other frontier models on several benchmarks, including the Vals Index, which covers finance, coding, legal and tax work. The company also describes it as more direct, less repetitive and better at following style instructions than earlier Gemini models. Those are Google's own claims, and The Verge notes the company has spent months trailing rivals.
For marketers and content teams, the practical points are cost and access. The API rate is an introductory offer, and Ars Technica reports it doubles after November 30. The Verge adds that per-token price does not always predict total cost, since models use different numbers of tokens for the same job. Google also describes a workflow in the Gemini app where Argon turns a folder of project files into a client proposal deck and sets up a scheduled task for future requests.
Before committing, test Argon on your own briefs, reports and content pipelines, and measure total spend per task rather than the per-token rate. Watch whether Google extends Antigravity access to lower tiers, since it has declined to say when or whether that will happen.
