Google’s newest high-end reasoning model is no longer reserved for a select group of cybersecurity defenders. But getting access still depends on which Google product you use — and what you’re willing to pay.
On October 13, Google expanded Gemini 4 Argon access globally to eligible paying subscribers, developers, and enterprises. The release follows its September 30 debut, when the company initially restricted the model to selected cybersecurity defenders.
Argon is available through consumer and developer products, each with different access requirements and costs. Its specialized cybersecurity capabilities remain restricted, leaving IT teams to weigh eligibility alongside security and deployment needs.
Gemini 4 Argon access: Eligible plans and pricing
Google’s October 13 announcement identifies several ways to access Argon.
| Access route | Eligible users | Requirements |
|---|---|---|
| Gemini app and AI Mode in Search | Google AI Pro and Ultra subscribers | Paid subscription |
| Gemini API and Google AI Studio | Developers and enterprises | Paid API tier or qualifying Ultra access to AI Studio |
| Google Antigravity | Google AI Ultra subscribers | Ultra subscription |
| Research program | Eligible scientists | Application and selection required |
Free Gemini users are excluded from the announced consumer rollout. A Google AI Pro subscription also does not independently provide Argon API access.
According to Google’s API documentation, introductory pricing is $2 per million input tokens and $10 per million output tokens through November 30, 2026. Those rates double on December 1. Eligible implicit-cache hits receive a 95% input-token discount.
To try Argon, Pro and Ultra subscribers can sign in to the Gemini app and select the model where available. Eligible subscribers can also use it through AI Mode in Search.
Developers can test Argon in Google AI Studio with qualifying access or use gemini-4-argon through the paid API. Google’s developer announcement also confirms Antigravity access for Ultra subscribers.
Separately, Google is accepting applications from scientists for six months of complimentary Antigravity access, covering up to 10,000 participants subject to eligibility and selection.
Argon’s capabilities and remaining restrictions
Argon targets complex work such as software engineering, document analysis, and cybersecurity research. Google reports improvements in extended coding assignments and professional reasoning, although those results do not guarantee similar performance across enterprise workloads.
Alongside Argon’s release, Google expanded Gemini app features, including background tasks and connections to more than 40 applications, such as Adobe and Shopify, according to its Gemini app announcement. Google also introduced Gemini agents that handle assignments across business apps, although some enterprise features remain in early access.
Cybersecurity access remains more restricted. Following Argon’s initial release to selected defenders, Google’s Fairwind Program continues providing approved participants access without certain cyber guardrails.
Google says security company Wiz used Argon to discover a critical healthcare software vulnerability missed by earlier models. The public version includes additional misuse protections, described in Google’s safety assessment.
Businesses evaluating Argon should test its performance against their workloads while reviewing API costs, permissions, and data governance. Google’s recently announced Android Enterprise AI controls also highlight the need to manage automated systems’ access to corporate data, although implementation details remain limited.
