Gemini 4 Argon is publicly available to Google AI Pro and Google AI Ultra subscribers through the Gemini app and AI Mode in Google Search, with an API offered to developers. Third-party evaluation group Artificial Analysis scored it 53 on its Intelligence Index v4.3.2, on par with Claude Fable 5.1 and GPT-6 Astra.
Google announced Gemini 4 Argon on September 30, 2026 as the first model in its Gemini 4 series. At announcement it was not publicly available: Google restricted it to vetted cyber defense organizations in the Fairwind Program and to thousands of its own employees, with access to paid API customers, Google AI Ultra users, developers, enterprises, and general users planned in stages. The disclosure came with Google's own benchmark table showing Argon ahead of GPT-6 Astra and Claude Opus 5.5 on knowledge work, long-context processing, and business automation.
Two weeks later Google opened general availability on October 13, 2026. Argon is now offered to Google AI Pro and Google AI Ultra subscribers through the Gemini app and AI Mode in Google Search, and an API is offered to developers. Google describes the model as built for multi-step coding and research and for finance, law, cybersecurity, and science, with the ability to read large volumes of documents and code. The company also disclosed internal use cases, including a Chrome codebase refactor and a robotics simulation pipeline.
The two stories diverge on how much the benchmarks settle. Google's announcement numbers were its own and showed Argon trailing on coding and OS tasks such as FrontierSWE v2 and OSWorld-2.0, while the later release carried an independent score from Artificial Analysis: 53 on Intelligence Index v4.3.2, on par with Claude Fable 5.1 and GPT-6 Astra. ASCII.jp noted that strong benchmark scores do not guarantee the model can do real work.

Google opened general availability of its Gemini 4 Argon AI model on October 13, 2026. The model, announced on September 30, 2026, had been limited to a small set of users including trusted cybersecurity personnel before this release. It is now available to Google AI Pro and Google AI Ultra subscribers through the Gemini app and AI Mode in Google Search, and an API is offered to developers. Google says the model is built for multi-step coding and research and for work in finance, law, cybersecurity, and science, with the ability to read large volumes of documents and code. The third-party organization Artificial Analysis scored Gemini 4 Argon 53 on its Intelligence Index v4.3.2, a value on par with Anthropic's Claude Fable 5.1 and OpenAI's GPT-6 Astra. ASCII.jp notes that strong benchmark scores do not guarantee the model can do real work.
