Google Rolls Out Gemini 4 Argon Globally at $2 per Million Input Tokens Introductory Price
The Gemini 4 Argon launch took place on October 13, 2026, when Google rolled out its flagship AI model to developers and businesses worldwide. Google CEO Sundar Pichai announced the release on X, saying it is available globally 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.
What Google Is Offering
Google says Gemini 4 Argon is built for deep, complex, multi-step tasks across real-world software engineering, robotics, science and enterprise workflows. The model was announced earlier this year and is designed for precision in demanding areas including coding, finance, legal research and cybersecurity. According to Google, it ranks number one on the Vals Index, an evaluation framework that tracks model performance across economic sectors such as taxation, legal and software development.
| Pricing tier | Input (per million tokens) | Output (per million tokens) | Validity |
|---|---|---|---|
| Introductory | $2 | $10 | Through November 30, 2026 |
| Standard | $4 | $20 | After the promotion |
| Cached input tokens | 95% discount | Not applicable | Introductory period |
The standard price is double the introductory price on both input and output tokens.
Access Across Google Products
The model is available to developers and businesses through the Gemini API. Google AI subscribers can use it in Google Antigravity, the standalone Gemini app and AI Mode in Google Search, depending on subscription tier.
Musk's Reaction
Elon Musk, owner of X, congratulated Pichai on the release. He also said that chief executives and executives posting directly on X is the best way to reach audiences and drive product sales, and that it is more powerful and effective than a press release.
Market and Sector Impact
The report does not include any share price reaction for Alphabet. The pricing structure places the model's entry cost at $2 per million input tokens for developers during the promotion, with the 95% cached-token discount lowering costs for repeated inputs. The standard rates take effect after November 30, 2026.
What to Watch
Track developer adoption during the introductory pricing window, any independent evaluations that confirm or qualify the Vals Index ranking, and how usage responds when standard pricing of $4 and $20 per million tokens applies from December.
