Foundation and Data Source

Feature	ChatGPT	Google Gemini (as part of Google’s AI Ecosystem)
Data Basis	A Large Language Model (LLM) trained on a massive, but static dataset of text and code up to a specific knowledge cutoff date.	A Large Language Model (LLM) often integrated with Google Search’s real-time index of the live internet.
Real-Time Info	It does not crawl the live web directly to answer queries, meaning its knowledge can be outdated or lack real-time context (like a practice’s current hours or a very recent medical update).	When integrated into Google’s search products (like AI Overviews), it can pull information directly from the live web and the up-to-date Google Search index.
Multimodality	Primarily text-centric (though advanced versions have visual and auditory inputs).	Natively multimodal, designed to process and understand text, images, video, and audio, which is highly relevant for medical imaging and visual content.

• Determines which medical or dental site appears in Google search.
• Fully integrated with Google Search, Maps, and local algorithms.
