Google has opened Gemini 4 Argon, its newest AI model for complex work, to Google AI Pro and AI Ultra subscribers in the Gemini app and in AI Mode in Google Search. The wider rollout began on October 13, 2026, about two weeks after Google first announced the model on September 30. Developers can also use it through the paid Gemini API, and AI Ultra subscribers get it in Google Antigravity, Google’s agentic coding environment. Free Gemini users are not included in this rollout. Here is what Argon is, who can use it and what it means for everyday users.
What is Gemini 4 Argon?
Gemini 4 Argon is a model built for long, multi-step tasks: complex coding, research, knowledge work inside companies and, according to Google, defensive cybersecurity. Google describes improved reasoning and coding compared with earlier Gemini models, and the app update also adds a smoother path from a chat to task-oriented work and connections to more third-party apps.
Google published benchmark results at launch, such as 77.9% on the DeepSWE coding benchmark. These are company-reported numbers, so it is worth testing the model on your own tasks before relying on them.

Why it matters
- The model race keeps speeding up. Argon follows OpenAI’s rollout of GPT-6 in ChatGPT; see GPT-6 in ChatGPT. The top assistants now update their models every few months.
- Best features go to paid plans first. Google is using its newest model to make AI Pro and Ultra more attractive, while free users wait.
- AI is moving from answers to tasks. Argon is designed for multi-step work, which fits Google’s push toward agents that complete tasks, not just chat.
- Developers get another strong coding option, alongside tools compared in GitHub Copilot vs Claude Code vs Cursor.
Should you upgrade to get it?
For most people, no. The free Gemini app still handles everyday writing, questions and image editing well. Consider Google AI Pro if you already use Gemini for long documents, research or coding several times a week, or if you also want its extra Google storage. Compare all three major assistants in ChatGPT vs Claude vs Gemini before paying.
