Key points
- Google opened Gemini 4 Argon to API users, AI Pro and Ultra subscribers in the Gemini app and AI Mode, and Ultra subscribers in Antigravity.
- API usage costs $2 for input and $10 for output per million tokens until November 30, then rates double, according to Ars Technica.
- Free users and Plus subscribers get no confirmed access; Google has not said when or whether that will change, per The Verge and Ars Technica.
- Google says Argon ranks first on the Vals Index and reports internal gains, including 35% more agentic code submissions in Antigravity.
Why it matters for marketers: Teams can test a new frontier model cheaply now, but the introductory rates expire November 30, so any workflow built on current token costs needs a budget for doubling.
Google has launched Gemini 4 Argon, its latest frontier model, after a limited preview to trusted cyber defenders. Developers and enterprises can reach it through the API, while Pro and Ultra subscribers get it in the Gemini app and AI Mode in Search. In Antigravity, Google's agentic development platform, only Ultra subscribers have access.
Google says Argon leads the Vals Index, which covers finance, coding, legal and tax work, and it claims wins over rival models in several domains. Those are the company's own claims. Google also says teams using Argon in Antigravity raised agentic code submissions by more than 35% and cut rollbacks by nearly a third. The Verge notes that Google had trailed rivals since Gemini 3 and frames this release as a return to the frontier race.
For marketers and content teams, the practical points are cost and access. The Verge reports the introductory API rates run around a fifth of what OpenAI and Anthropic charge for comparable models. Ars Technica reports that they double after November 30. The Verge also cautions that lower per-token prices do not guarantee lower bills, since models use different token counts for the same task.
Google says Argon follows style instructions better than earlier Gemini models, hedges less and avoids clichés. It also showed a proposal-deck workflow in the Gemini app. That is relevant to content production, though it comes from Google's demonstrations.
Next, watch whether Google extends Argon to Plus and free users or to lower Antigravity tiers. If you plan to build on the API, test real token use on your own tasks and model the post-November costs before committing.
