major change Rules or requirements changed
Google renamed the AI Mode model from Gemini 3 Pro to Gemini 4 Argon in Search Help, replacing the description and updating availability: the English-only restriction was removed and Google AI Plus was dropped from eligible plans, leaving Pro and Ultra subscribers 18 and above. A related resource link for 'AI Overviews and more' in Search Labs was also removed.
Lincoln Digital's AI Overview
This suggests AI Mode's advanced model may now be available to users in more languages, but only to those on Google AI Pro or Ultra plans, which could affect who sees AI-generated answers. Site owners and SEOs may want to monitor how the new model's improved instruction-following changes AI Mode's handling of multi-step queries, though these documentation changes do not directly alter ranking systems.
