Google has opened global access to its flagship AI model Gemini 4 Argon in the Gemini app, in AI mode in Search for subscribers to Google AI Pro and Ultra, and also via an API for developers and companies.
Where and who can access the model
Gemini 4 Argon has appeared in the Gemini app and in the AI mode in Search, and is available to subscribers to Google AI Pro and Ultra. Developers and companies can connect to the model via a paid API.
The model was unveiled at the end of September, but it was initially provided to a limited group of cybersecurity specialists. Google used that period for additional security testing before the wider rollout.
Capabilities and supported data formats
Argon is aimed at long, multi‑step tasks in programming, finance, law, science and cybersecurity. It supports text, images, audio and video, and the combined input and output limit reaches 1 million tokens.
A Tasks mode has been added to the Gemini app, in which Argon can carry out jobs in the background via connected Google services and third‑party apps. More than 40 services are supported, including Adobe, Shopify, Instacart and OpenTable.
The model can process a set of documents, prepare a presentation, draft a letter to a client and configure repetition of the process for future requests. For macOS, Google added the programming interface Google Antigravity, which eases the transition from conversation to working with code. Argon also shows a change in response style: it is more direct, repeats itself less, follows a specified style better and more frequently reports progress on long-running tasks.
Pricing and comparison with competitors
Gemini 4 Argon is available via the paid Gemini API. Until 30 November the introductory price will be $2 per million input tokens and $10 per million output tokens; after that the rates will rise to $4 and $20 respectively.
According to internal tests, Argon outperforms competitors on a range of professional tasks, programming and analysis of long context and multimodal data, but GPT-6 Astra and Claude Opus 5.5 are stronger in some programming, computer control and scientific tests. A separate version of Argon with relaxed restrictions for cybersecurity tasks will continue to be provided to vetted specialists through the Fairwind programme.
