Why it matters

Argon is Google's answer to the latest frontier models from OpenAI and Anthropic, and its pricing and reach across Search and the Gemini app could shift where developers and businesses build.

Google first announced Gemini 4 Argon on September 30 and gave it only to a group of trusted cyber defenders through its Fairwind Program. The October 13 launch opens it to paying developers, enterprises and Pro and Ultra subscribers. Sundar Pichai posted a teaser video about 20 minutes before the launch post, and Google DeepMind, the Gemini app account and Logan Kilpatrick posted first hand announcements. Google later posted that its engineers used Argon to split core webpage handling out of a 6 million line legacy folder in Chromium's 40 million line codebase, eliminating a category of Chrome crashes in weeks rather than months.

Deep dive

On October 13, Sundar Pichai posted: Gemini 4 Argon is here, saying it is available globally for developers and enterprises in the paid tier of the Gemini API and the Gemini platform, for Ultra subscribers in Google Antigravity, and for Ultra and Pro subscribers in the Gemini app and Search.

Google's launch post says Argon is built for complex scientific, coding and agentic problems, with a 1M unified input and output token limit in the Gemini API and a new continuation protocol. It launches at an introductory price of $2 per million input tokens and $10 per million output tokens, with cached input 95% off, rising to $4 and $20 after November 30.

Koray Kavukcuoglu of Google DeepMind wrote that Argon targets real world software engineering, enterprise knowledge work and cybersecurity defense, including long code migrations. The Gemini app blog says Argon answers more directly with less hedging, that Antigravity's agentic coding interface is now inside the Gemini macOS app, and that Gemini now connects to more than 40 apps such as Instacart and Shopify.

Logan Kilpatrick posted that the model was tested by over 100,000 people at Google over the last month. Google said in September it took part in the US government's voluntary process for pre release model testing before widening access.

Cursor said Argon is available in its editor and scores 52.8% on CursorBench at default effort, on par with Opus 5.5, and Google DeepMind and Google posted that Argon learned cornhole and taught Apptronik's Apollo humanoid to sink seven throws in a row.

Artificial Analysis posted that Argon ranks equal to GPT 6 Astra on its Intelligence Index at about 60% of the cost per task while the discount lasts, with the lowest hallucination rate among leading models on its AA Omniscience test, and Google's Jun Cheng posted that Google is offering 10,000 scientists the highest Antigravity usage tier free for six months. Logan Kilpatrick later shared a video conversation about Argon with Sergey Brin and Gemini leaders. Anca Dragan of Google DeepMind linked a Gemini 4 safety report on its capabilities and mitigations.

What to expect next

Watch independent benchmarks and developer reviews of Argon against the newest OpenAI and Anthropic models, and whether usage grows quickly while the introductory price lasts through November 30.

Also watch when Google releases the rest of the Gemini 4 family it promised, whether Argon reaches free users, and how its cybersecurity capabilities are handled as access widens beyond the Fairwind Program.
