Gemini 4 Argon is the first model of the fourth Gemini generation, opened to everyone on October 13, 2026. Google built it for long, demanding work: refactoring large codebases, multi-step agentic tasks, financial and legal analysis. It understands text, images and PDFs, with a context of a million tokens. Available on ChatPlus on the PRO plan.
Argon is the first Gemini 4 model. Google unveiled it on September 30 but at first gave it only to cybersecurity specialists and trusted testers. For two weeks the model was tested on real work and its safeguards were tuned, and on October 13 it opened to everyone: in the Gemini app, the API and the Antigravity development environment.
Inside Google, Argon is already rewriting large projects. The Chrome team used it to untangle a six-million-line folder of browser features: a refactor across hundreds of files took weeks instead of months. The model was trained to say so honestly when something did not work, and to stop and ask for confirmation before an irreversible step.
It is not only about code. In Google's tests Argon beats its rivals at financial analysis, legal work and understanding long videos, and it writes more directly than earlier Gemini models: less hedging, fewer repeats and clichés. It still trails in terminal tasks, where Claude Opus 5.5 leads for now.
On ChatPlus, Gemini 4 Argon is available on the PRO plan. Use it for large documents, code and analysis — and compare it with GPT, Claude and Grok in the same window.
