Google Expands Gemini 4 Argon Access to Developers and Paid Subscribers

Jordan’s Al‑Ghad reports that Google has begun a wider rollout of its Gemini 4 Argon AI model, making it available to developers, businesses and paid subscribers while users of the free version still cannot access it.

The model was unveiled in late September. Initially, access was limited to a small group of testers, trusted partners and government entities as Google carried out necessary tests. Two weeks after that initial launch, the company decided to expand access and make the model available to new categories of users worldwide.

Rollout to Developers and Businesses

Gemini 4 Argon is now available globally to developers and businesses through the paid tier of the Gemini API, AI Studio and Google’s Gemini platform. Subscribers to the Google AI Ultra plan can also use the model via the Antigravity platform, while those on the Pro and Ultra plans can access it through the Gemini app and Google Search’s AI Mode.

Pricing and Performance Claims

Google says Argon is primarily designed for complex tasks that require advanced analysis and reasoning rather than quick answers to basic questions. It promotes the model as suitable for programming, finance, legal work, cybersecurity, science and any work that needs extensive processing and in‑depth analysis before reaching conclusions. According to Google, Argon currently ranks first on the Vals benchmark, which measures AI performance across finance, programming, legal work and taxation. The company has introduced introductory pricing for API use: $2 per million input tokens and $10 per million output tokens, together with discounts of up to 95 % on cached input tokens that can be reused without full reprocessing. Google noted from the outset that customers using paid API services and subscribers to the Google AI Ultra plan would be among the first to benefit.

Real‑World Applications

Google cites several practical examples. The model helped increase code submissions produced by the company’s AI agents by more than 35 % while reducing code rollbacks by about one‑third. Rollbacks refer to restoring code to an earlier version after errors are found in new changes. Chrome engineers used Argon in a large‑scale refactoring of the Chromium project, which involves hundreds of files in a codebase of roughly 40 million lines. The model was also employed to improve Google’s suite of tools for building AI agents, to accelerate the quantum‑chemistry package XTB, to enhance reasoning in the Gemma 4 model, and to support work in cybersecurity and scientific research.

Free Users Still Excluded

Despite the significant expansion, access remains limited for ordinary users who rely on the free version of Gemini. Individuals can obtain Argon only by subscribing to either the Google AI Pro or Ultra plan. Free Gemini users will have to wait for any future decision by Google to widen access, as the current announcement does not include this group.

The expansion marks another step in Google’s strategy to strengthen its position in the advanced AI market by coupling powerful models with practical applications in programming, scientific research and business. Source: Al‑Ghad.
