This Tuesday (13), Google expanded access to the Gemini 4 Argon, its new artificial intelligence model aimed at programming, research and complex professional tasks. The technology arrives for paying developers and subscribers of the Google AI Pro and Ultra plans, with a pricing change planned for December: API prices will be doubled after November 30.
Announced on September 30, Argon was initially available only to selected participants, mainly cybersecurity experts. The expansion marks its commercial arrival, with integration into the Gemini app, Google Search's AI mode and the company's development tools.
The model was developed to perform tasks that require multiple stages of reasoning, including financial analysis, legal research, programming and identification of vulnerabilities. Google also expanded its generation limit to up to 1 million output tokens, compared with 64,000 in previous models.
API will have doubled prices and access to Antigravity will be restricted
The API debuts with promotional rates of US$ 2 per million input tokens and US$ 10 per million output tokens. According to Reuters, the values will rise to US$ 4 and US$ 20, respectively, after November 30.
The change represents a 100% increase in both categories. Google also offers a 95% discount for cached input tokens during the promotional period, a feature that can reduce expenses in applications that reuse information.
The price per token, however, does not alone determine the cost of an operation. Different models can consume different amounts of tokens to complete the same task, making the actual expense dependent on the volume processed.
Access also varies depending on the product. Pro and Ultra subscribers can use Argon in the Gemini app and in Search's AI mode, while use of the model in the Antigravity programming environment is restricted to the Ultra plan. Developers and companies can access it through the paid development tools.
In the tests released by Google, teams that used Argon in Antigravity increased by more than 35% the submission of code produced by AI agents and reduced by nearly a third the reversions of changes. The results were presented by the company itself, with no independent validation indicated in that data.
The expansion also reaches scientific research and digital security. Google will offer six months of free access to the highest tier of Antigravity for 10,000 scientists and will expand its Fairwind program to hundreds of new partners specialized in cyber defense.
Among the organizations that participated in the early tests are Deloitte, LexisNexis, Ambience Healthcare and Isomorphic Labs.
