Gemini 4 Argon Quietly Surfaces in Gemini App Model Picker

On the afternoon of October 14, numerous users unexpectedly spotted an unreleased model, "4 Argon," in the Gemini App's model picker. Positioned for "Complex tasks," it appeared alongside 3.5 Flash-Lite, 3.8 Flash, and 3.1 Pro, with no prior announcement from Google.

Confirmed

• Multiple users (across regions/languages including India, Brazil, and Hebrew interfaces) shared screenshots showing a "4 Argon (Complex tasks)" option in the model picker, marked "New," with three independent thinking level settings: Low (fast and efficient), Medium (balanced), and High.
• Subscription access varies: some Pro and Ultra subscribers reported being able to select it directly; other screenshots show the model as "Unavailable," with a hover note stating "Gemini 4 Argon is currently only available to Ultra plan subscribers"; some free users were prompted to upgrade to Pro to unlock it. There are also reports of it being unavailable for Pro subscribers, suggesting a possible staged rollout.
• A Hebrew-interface screenshot (@TheJoseph10) shows 4 Argon labeled at the "ultra" tier, distinct from 3.1 Pro (flagship), and not directly replacing 3.1 Pro.
• "Gemini 4 Argon High/Medium" options also appeared in Google Antigravity, but multiple screenshots mark them "Unavailable," so it cannot actually be used at the moment.
• When asked about itself, the model replied it "cannot discuss or assist with this new release for now" (@Cyrone007); another user asked it to identify itself and got "Gemini 4 Argon—Google's latest flagship model, built for deep reasoning, complex multi-step workflows, and real-world software engineering" (@Puzzleheaded-Club160), though such self-descriptions are not necessarily reliable.

Unconfirmed

• Whether Argon is actually Google's next-generation flagship Gemini 4, its full capabilities, and its official release date all remain unknown; Google has made no announcement, and authenticity rests on user screenshots—it could be internal testing or an A/B rollout.

Why it matters

• This is the first large-scale consumer-facing appearance of the Gemini 4 series; if confirmed, it would mean Google's next-generation flagship is arriving notably faster than expected, making it worth tracking official confirmation and subscription-tier pricing closely.
