Google is set to expand its Gemini AI service portfolio, potentially introducing a new premium subscription tier named "Gemini Ultra." Currently, the company offers the "Gemini Advanced" service as part of its Google One AI Premium plan, priced at $19.99 per month. This plan includes access to the Gemini 2.5 Pro model, video generation capabilities, Workspace integration, and various other features. Recent code leaks hint at Google's intention to introduce an even higher-tier service, enabling users to upgrade and unlock additional feature limitations. Moreover, the discovery of plan names like "Premium Plus AI" within Android applications suggests that Google is actively enhancing its AI service offerings to cater to the diverse needs of its user base.
