A Reddit user's Gemini app screenshot shows an unannounced '4 Argon' model (tagged for complex tasks) sitting alongside '3.1 Pro' in the model picker, with free users prompted to upgrade to Pro to unlock it. The picker also shows 'Automatic (Gemini 3 models)'. Google has not officially confirmed the model; this appears to be a staged rollout or leak.
