Google's Gemini AI has integrated seamlessly into Android devices and Google Search, with the recent release of the Gemini 2.0 Flash model, which offers improved performance over the 1.5 Pro model. The Google app version 15.49.42 beta introduces a feature allowing users to select from different Gemini models on Android, including Gemini 1.5 Pro, Gemini 1.5 Flash, and Gemini 2.0 Flash Experimental. The 2.0 Flash Experimental model was initially unavailable but is now part of the testing options in version 15.50.37 beta. The "Experimental" label suggests potential instability, and users are advised to use the 1.5 Flash for routine inquiries and the 1.5 Pro for in-depth research. The rollout for stable branch users is expected soon.
